I worked on a Blast Furnace starting in the early 1970s and at that time they would skim the slag off the iron and into the pots. And if you filled all the pots you would divert into a pit. The pots would then be dumped into a much larger pit away from the furnace. They would be molten and it would light up the sky for a minute or two. When the pots would come back and be spotted for another cast, liquid lime would be sprayed on the inside wall to make any skull build up slide off easier during the next dump. One other interesting thing would happen if you were making hot 2800F iron and it was limey basic slag, with a higher B/A ratio. You would under fill the pot at least 6" from the top, because once the top surface had a thin crust from cooling it would swell up from gases and start spilling on the ground. Our technique was to throw a wood board on top or moist clay balls. Either would have a boiling effect and allow the gas to escape.
you sure know what you're talking about. I worked at us steel a long time ago. Gary works. they used to spray the inside of the cinder ladles with lime to keep the slag from sticking to the cinder ladle. sometime they would flush the slag into a pit full of water. as the molten slag would be coming out of the furnace it was mixed with water and the result would be like popcorn. they would use that stuff for paving material.

You should consider writing. Your words had me standing right there alongside you. If you haven't taken writing classes you have a natural gift, well, even if you have, too.
Some internet searching: Slag is stony waste matter separated from metals during the smelting or refining of ore. Not sure what a skull is, but based on the video, I would assume the "skull" is the stuff in the solid chunk dropped out of the slag pot. A slag pot is a metal ladle for collecting molten slag flowing from the tap hole of a steel-smelting furnace during smelting. It is positioned under the furnace on a car that moves along a special trestle for slag removal. Emptying slag pots is time-consuming and often difficult. Using chisel operated hammers and banging slag pots against hard objects to remove the slag can additionally damage the pot and may be dangerous for staff deployed on site. Fractum breakers have been designed to efficiently and effectively de-skull slag pots without causing damage. This is achieved by adjusting the breaker’s impact power, enabling the adaptation of energy levels, depending on the task. The steel milling breakers have been designed to remove solidified skull from slag pots, which has a higher success rate compared to traditional de-skulling techniques like oxy-cutting. Clients have hailed the breaking technology for its ability to cope with slag pots handled by both ladles and overhead cranes.
The other part of this I left out was the whole point of these skulls. Now, I don't know for sure, but it seems like there are two ways to dump slag into a slag pit (to get rid of it or store it, I'm not sure). The first way is to move the slag pot on the car (train rails) to the slag pit before the slag cools and hardens and is still molten. Then you dump the slag like river of lava into the slag pit. But apparently this takes up a lot of room and I would guess later recovery of the slag for industrial purposes would be more difficult. So instead, you can let the slag cool into these hard boulders with a creamy molten centers called skulls. Then you can dump out the skulls into the pit and it takes up a lot less room. There is a video on here of a skull exploding, I assume from a build up of pressure. So that's one reason why they probably break them up. Another is to just speed up the cooling process of the skull so it's not a dangerous ball of lava waiting to leak onto something important.
Stupid question is stupid, but as basic slag is a mix of both mineral and metal oxides, would (instead of pouring it into pits, or de-skulling, letting it cool, then grinding it up, and adding it to concrete powder) it possible for molten basic slag to be poured into molds, and cooled until fully hardened ala pre-fab concrete ... in other words, would solid basic slag have the same properties of some pre-fab concrete, or would it just crumble under compression ..?
I don't know, but from watching other videos, it looks like slag deposits once hardened have to be jackhammered out of the molds. So I'm guessing that they need to get the stuff out of molds pretty quickly. But hopefully an expert can weigh in.
Wow,the memories came flooding backs after watching this and reading the comments of others. I used to do that in a steel mill in Oregon...but I was given a Caterpillar 977 track dozer with a bucket to do that. This being the Pacific North-wet... one of those skulls broke open on a small puddle of water!! Boom boom boom,out went the lights! 😄😆 But I lived and was ok!

In '68, I worked in a blast furnace. The hot iron flow down a channel to a large container called a "pig". The pig was part of a Railroad car. The Slag went into a large bowl also mounted on a Railroad car. The slag was dangerous. We had to coat the bowl with lime. The bowl had to be completely dry. If a water pocket was formed in the slag bowl, then the slag would blow up. Hot slag was dangerous to be around. If slag got on your clothes, then it would burn straight threw to you skin, and burn a hole in your skin. Iron was not a problem. Iron didn't explode, and if hot iron landed on your clothes it brushed off.
I too worked at a Pig Machine before I moved up to the Blast Furnace. I was a Sticker Man. If one of the pigs stuck in the mold (usually because the mold had a crack which allowed the iron a place to "grab" on to) I was the guy a took a bar and hit it while it was stuck upside down. You did work with a heavy cage gauge steel cage over you but.. if one didn't release and fall to the ground after striking it, you would leave the cage and keep smacking it until it dropped. You had to be strong, agile and dumb to be good at it. I was all of the above.... And then you had to move the pigs to a pile manually away from the line.
THIS reminds me of the Steel Mills where I grew up! A Locomotive Engineer, my father often pulled strings of "Crucible Cars" from the blast furnaces to one of several casting plants nearby, to be turned into Tools, Engine Blocks and numerous other items that kept our world turning from the 1950s until 1985, when he retired! Unusual looking, these Very Heavy and Extremely HOT Rail Cars, rolled through the middle of several residential neighborhoods! It was the one job that my father disliked! He was always "Very Afraid" of one (or more) of the cars to derail and overturn, or to simply Split Open and spill it's load of Tons & Tons of Liquid Fire! One tiny drop of 2000 to 3000 degree (or more) of molten metal, will ignite nearly anything it touches and "that" always worried my father, terribly! Most of those homes were in economically depressed neighborhoods and "that fact", made my father worry even more!
@Slick Armor Yeah, that's basically it, because poor people already don't have much, and they would generally have a harder time recovering from something like that than people with more money.
Yeah them little “drops” specks/sparks. Tossing in things or getting samples or temp poles into the ladle. They would come back an make burns. Tiniest of sparks would hit our uniform go through it or hit you in the neck and just roll down your body in your clothes from moving around to keep from burning. The worst when whatever it hits if you didn’t move quick enough it would stick an keep burning. Vs the moving around to keep it moving not to to bad that it cooled enough that it wasn’t a issue an keep working. If it hit the boots an some way slipped through the tongue of the boot them definitely burned. Can’t shake your foot around in them to not be. It just sits in that spot. Fun times Kinda like being attacked by yellow jackets lol. If someone was jumping or shaking or whatever ha ya knew they were getting stung up ha.

In the 70's I worked in the steel mill in the railroad car repair dept. I worked on the torpedo shaped iron cars and the cinder ladle cars. After the ladle cars were filled at the blast furnaces, they were taken across the river to a special dump. Occasionally part of the skull would get stuck in the bottom of a ladle. That car would be set aside to cool. After that coing time the car would be brought into our building. I had to climb up to the overhead crane that was who knows how high off the ground. My helper would connect two cables to the top of the ladle and I would lift it out of the cradle and lay the ladle on the ground. My helper would disconnect the two cables and connect one heavy cable to the bottom of the ladle. I would carefully lift it off the ground and move it to the far end of the building where we had an ingot that was partially buried in the ground. I would lift the lift the ladle even with the ingot and get it swinging like a bell, then moving the craneso the ladle smacked the ingot. One or two smacks and the piece of skull would fall out. Immediately I had to move the crane back to avoid being gassed. Put the ladke on the ground and the helper hooked up the two cables, reinstalled the ladle in the frame of the car. Then the car was put back in service. Hard to believe we did crazy stuff like that.
This reminds me of my Uncle who was actually a Fractum Model 100. He used to take me to work and deskull hot metal all day until he was sold for scrap metal in 1994.
+Thad ward Yeah, and it was pretty cool, actually! Have you ever seen a massive ball of red hot metal waste being broken by a machine sledge hammer before?
When I was a teenager working the Homestead mills in the 50s, we didn't have impact hammers, broke the slag by hand with a 5 lb hammer and cold chisels. "If you get burned, you get burned" the foreman told us.
@@Hust91 they crush it up cool it down and reuse it. Or sell it to concrete plants. They recycle everything. Run the dust thru baggers call it iron oxide. It's the neatest thing.

@@jerrykinnin7941 Ah, so the slag isn't just waste it has some value still? Thank you for your answer, I appreciate it. And honestly, we basically made robot giants to help us do very specific stuff. Or rather, found ways to make ourselves robot giants. It is incredibly cool.
I hail from an old steel & coal town, used to be iron, limestone & coal area. Here they started small in the 1700s and by my time, the slag heaps had become mountains. The slag and coal wastes, were simply hauled up to the tops of the ‘tips’ mountains and added to the top-sides of said mountains. Some would slide down and some would stick fast. It takes a born ‘n’ bred local, to be able to look at a mountain and tell if it’s a natural mountain or a manmade mountain or a bit of both. Slag was often poured into earthen pits and left to cool into blocks. These blocks are typically 4-5ft. long x 1ft. high x 1-2ft. wide. They were used to build walls, where the strength of stone was needed but the looks of brick was not required. There are still walls made of these blocks, they made good retaining walls. Typically held by rough ash mortar; as suggested, they were used where a strong structure was needed at a very low price. Though I takes a crane to move them.
@@weatheranddarkness - Those that I know of, have become parts off privately funded home builds. They’re mostly grown over with ivy/creepers or have been rendered over. When I was in my early teens, me and my friends were on our way to some waste ground. This entailed climbing down or jumping off one such wall. The wall must have been well over 100yrs. old at the time. The rough ash+lime mortar was crumbling. One moment I standing on the wall and the next, the top of the wall slid, sending me into the brambles below. The brambles broke my fall, which was good if a little prickly. Much to my friends’ amusement. However, before I could extract myself, the rest of the wall collapsed along apx. 12ft., (3.7m) burying me in the process. Broke off the end of my left fibula and luckily, a block rolled over my head while being partly supported by moving rubble. That one just broke my nose… could have been worse. My friends dug me out with the bare hands; and a couple of lads on their way to play tennis, bundled me into their 1960s Mini and took me home. Another trip to the hospital for me from there. Most of that wall still exists but has been rendered over or buried by garden make-overs, (the houses weren’t there in my teens).
The mill i haul to has these wishbone shapped haulers that take the slagpots into a building for "de-sculling" its cool to watch them at night. All glowing and steaming in the rain. Slag is used as an ingredient in concrete.
If it is blast furnace iron slag then you're in the money! Allow it to cool, pulverize it, crush it, grind it, and mill it until it is as fine a baby powder or bleached white wheat flour powder. Mix an equal proportion of slaked lime powder with an equal proportion of blast furnace iron slag powder and an equal proportion of clay powder. Mix and then add water after it has totally blended together while continuing mixing it. And add some sand and gravel. And you got a modernized version of Smeaton concrete. The original Smeaton cement foundation in England facing the continous pounding of the Atlantic ocean is still intact and as food as new after almost 120 years of service as a lighthouse. The lighthouse has to be dismantled and place further inland because the natural rock formation is being worn away by the Atlantic waves but the Smeaton cement foundation is still as good as new and virtually unaffected by the corrosive seawater itself. But no one has ever tried using steel slag as part of the cement mortar and concrete mixture. www.centuryhouse.org/Next/wp-content/uploads/2015/01/2006summ.pdf
I had a 1985 Dodge Power Ram D50 4x4 pickup truck that I entered into every ugly pickup truck contest I could find. I named it, "Slag." In two years of ownership, I made just under $10,000 in just prize winnings from Slag. One day, Slag was stolen from a parking lot at work. Four months later, Slag was found in parts because it was parked overhanging a railroad so the train would hit it. I still miss Slag, the best $100 pickup truck anybody could ever have. I still have Slag's shiftstick and hood ornoment with a picture.

@@venomsoul1147 For the last 26 years, I have been in the company of the RMS Stargazer. The Stargazer and I started our journey together in 1996. She started her life with me as a 1997 jeep Wrangler Sport, convertible. If ever anything could be a friend, it has been Stargazer. I have been through two careers, 10 friends, three homes, and various economical levels in life. I lost my home this January of 2022 in a fire. The Stargazer and I spent three nights together because I had nowhere to stay. All that was saved from the fire was what was Stargazer and me. It was a chest of tools, a length of nylon rope, a shovel, duct tape, plastic bags, crow bars, and my five work uniforms. Work dismissed me until I got my house in order because I was placed in a hotel very far away. During my hotel residency, Stargazer stopped running for the first time in our life together. For awhile, I thought of calling a tow truck and ending our journey together. But with nothing else to do at the hotel, I took off the wiring harness, (no easy task) and started repairing it. It took over a month to remake the wiring harness. It was a labour of love. Early July, I reinstalled the rebuilt wiring harness and Stargazer came back to life. She ran terrible due to the damaging voltages that surged through her when she went into a coma. But I lovingly kept repairing her. Today, she runs like new again. She has been with me through so much. No human, "friend," could ever be so wonderful and loyal. I love you Stargazer. I love you forever.

Things should be more suitable for repair.
Just going to take an uneducated guess here: I'm guessing the slag pot is the train car - it's used to carry the unwanted (non-metallic) leftovers from the smelting process. The Fractum Model 100 is a tool for breaking up the chunks, as it would be easier to move small chunks of slag (e.g.: use a regular front-end loader). Deskulling is the process of emptying a slag pot where things have already cooled to the point of where they aren't easily removed from the slag pot. That's just a guess, though.
When you smelt iron ore the melt separates into two parts: iron and lava rock. The molten iron sinks to the bottom of the melt and the molten lava floats on top. The lava is a waste product and is either skimmed or drained off the top of the melt and is removed for disposal as slag.
It's simple. A dualized parping couplet is rutted into a fissure known as a Sultan's Hat, thereby releasing super-ingot into a non-restrained region that you see in the video.
@@Spectans1 a drop ball is like a wrecking ball only it's usually attached to a crane overhead. deskulling is knocking out the slag that sticks to the inside of the cinder ladle. I worked in a steel mill a long time ago. back when America still had a lot of steel mills.
At my previous job they had this underground pits where the crane dumps orange hot semi hardened slag in. Then they lower the lid like a toilet seat, and spray water from the lid and suck out the steam through the chimney through an underground tunnel. The temperature shock turns slag into loose rubble and sand, then they use an excavator to manually scoop them out into a truck. Then it gets sent to a yard where they run it through a conveyor that separates still usable iron out and filters the rest by size. Much of it done without external contractors. Really precarious builds, but they work lol. Obviously nobody calculated anything so from there we do continuous adjustments and improvement such as hand rails, making walkways stronger, adjusting the angle of the mesh, etc. But theres this crazy situation on the vibrator feeder below a hopper. This one hook on the trough keeps breaking at the exact same spot and people just kept welding on bent pieces of rebar, which then breaks again, just like the original hook. At least 4 broken off bits of the same design welded one atop another, yet nobody thought maybe they should do an upside down U shape or just try something else so it doesnt keep breaking. Anyways idk what they do with the slag but the dust and skull with iron in them gets fed back into the furnaces.
You could watch engineers empty slag in to a ravine when Bethlehem Steel was in operation. That was a sight to see, my old man is a rail fan, he use to take me trainspotting all the time as a child and watching slag being dumped was one of those things.
It would only take a couple days. The outer crust acts as a heat sink instead of an insulator. So it is actively drawing out the heat. You can see how thick the crust was already and that is just after a few hours.
It's an interesting though. Consider that earth is somewhat similar to this slag lump, except about 4 million times larger in diameter (assuming 3m diameter slag) but earth is still glowing hot inside after more than 4 billion years.
Kevin Klika a pot of oxidized junk from a steel mill. It was cooled on the outside so the could slide it out like sliding a muffin out of a muffin pan, but the inside is still hot because it takes forever to cool down.
Slag is the impurities from the steelmaking process. This pot was where they transported the slag in. Now they dumped it out, along with the refractory lining of the pot, and are breaking it up so it cools. Slag can be recycled into road materials or other usual when it is cooled and ground up. You're welcome, from a lady engineer.

A slag pot is a metal ladle for collecting molten slag flowing from the tap hole of a steel-smelting furnace during smelting. It is positioned under the furnace on a car that moves along a special trestle for slag removal.
Emptying slag pots is time-consuming and often difficult. Using chisel operated hammers and banging slag pots against hard objects to remove the slag can additionally damage the pot and may be dangerous for staff deployed on site.
Fractum breakers have been designed to efficiently and effectively de-skull slag pots without causing damage. This is achieved by adjusting the breaker’s impact power, enabling the adaptation of energy levels, depending on the task.
The steel milling breakers have been designed to remove solidified skull from slag pots, which has a higher success rate compared to traditional de-skulling techniques like oxy-cutting. Clients have hailed the breaking technology for its ability to cope with slag pots handled by both ladles and overhead cranes.
Feint that's some intense googling. thx bro
Feint thank u boss, i was about to embark on a quest to figure out why this is so awesome lol
The other part of this I left out was the whole point of these skulls. Now, I don't know for sure, but it seems like there are two ways to dump slag into a slag pit (to get rid of it or store it, I'm not sure). The first way is to move the slag pot on the car (train rails) to the slag pit before the slag cools and hardens and is still molten. Then you dump the slag like river of lava into the slag pit. But apparently this takes up a lot of room and I would guess later recovery of the slag for industrial purposes would be more difficult. So instead, you can let the slag cool into these hard boulders with a creamy molten centers called skulls. Then you can dump out the skulls into the pit and it takes up a lot less room. There is a video on here of a skull exploding, I assume from a build up of pressure. So that's one reason why they probably break them up. Another is to just speed up the cooling process of the skull so it's not a dangerous ball of lava waiting to leak onto something important.
Stupid question is stupid, but as basic slag is a mix of both mineral and metal oxides, would (instead of pouring it into pits, or de-skulling, letting it cool, then grinding it up, and adding it to concrete powder) it possible for molten basic slag to be poured into molds, and cooled until fully hardened ala pre-fab concrete ... in other words, would solid basic slag have the same properties of some pre-fab concrete, or would it just crumble under compression ..?
I don't know, but from watching other videos, it looks like slag deposits once hardened have to be jackhammered out of the molds. So I'm guessing that they need to get the stuff out of molds pretty quickly. But hopefully an expert can weigh in.

2:05 The world's first hot-pocket is demonstrated to investors, 1976, Colorized.
In '68, I worked in a blast furnace. The hot iron flow down a channel to a large container called a "pig". The pig was part of a Railroad car.
The Slag went into a large bowl also mounted on a Railroad car.
The slag was dangerous.
We had to coat the bowl with lime. The bowl had to be completely dry. If a water pocket was formed in the slag bowl, then the slag would blow up.
Hot slag was dangerous to be around. If slag got on your clothes, then it would burn straight threw to you skin, and burn a hole in your skin.
Iron was not a problem. Iron didn't explode, and if hot iron landed on your clothes it brushed off.
I too worked at a Pig Machine before I moved up to the Blast Furnace. I was a Sticker Man. If one of the pigs stuck in the mold (usually because the mold had a crack which allowed the iron a place to "grab" on to) I was the guy a took a bar and hit it while it was stuck upside down. You did work with a heavy cage gauge steel cage over you but.. if one didn't release and fall to the ground after striking it, you would leave the cage and keep smacking it until it dropped. You had to be strong, agile and dumb to be good at it. I was all of the above.... And then you had to move the pigs to a pile manually away from the line.
@@rayp450 right

THIS reminds me of the Steel Mills where I grew up! A Locomotive Engineer, my father often pulled strings of "Crucible Cars" from the blast furnaces to one of several casting plants nearby, to be turned into Tools, Engine Blocks and numerous other items that kept our world turning from the 1950s until 1985, when he retired!
Unusual looking, these Very Heavy and Extremely HOT Rail Cars, rolled through the middle of several residential neighborhoods! It was the one job that my father disliked! He was always "Very Afraid" of one (or more) of the cars to derail and overturn, or to simply Split Open and spill it's load of Tons & Tons of Liquid Fire! One tiny drop of 2000 to 3000 degree (or more) of molten metal, will ignite nearly anything it touches and "that" always worried my father, terribly! Most of those homes were in economically depressed neighborhoods and "that fact", made my father worry even more!
@Slick Armor Because some people have empathy.
@Slick Armor Yeah, that's basically it, because poor people already don't have much, and they would generally have a harder time recovering from something like that than people with more money.
Yeah them little “drops” specks/sparks. Tossing in things or getting samples or temp poles into the ladle. They would come back an make burns. Tiniest of sparks would hit our uniform go through it or hit you in the neck and just roll down your body in your clothes from moving around to keep from burning. The worst when whatever it hits if you didn’t move quick enough it would stick an keep burning. Vs the moving around to keep it moving not to to bad that it cooled enough that it wasn’t a issue an keep working.
If it hit the boots an some way slipped through the tongue of the boot them definitely burned. Can’t shake your foot around in them to not be. It just sits in that spot.

I have no idea what I just watched... but I loved it.
When I searched for "red hot slags" I did not expect this.
In the 70's I worked in the steel mill in the railroad car repair dept. I worked on the torpedo shaped iron cars and the cinder ladle cars. After the ladle cars were filled at the blast furnaces, they were taken across the river to a special dump. Occasionally part of the skull would get stuck in the bottom of a ladle. That car would be set aside to cool. After that coing time the car would be brought into our building. I had to climb up to the overhead crane that was who knows how high off the ground. My helper would connect two cables to the top of the ladle and I would lift it out of the cradle and lay the ladle on the ground. My helper would disconnect the two cables and connect one heavy cable to the bottom of the ladle. I would carefully lift it off the ground and move it to the far end of the building where we had an ingot that was partially buried in the ground. I would lift the lift the ladle even with the ingot and get it swinging like a bell, then moving the craneso the ladle smacked the ingot. One or two smacks and the piece of skull would fall out. Immediately I had to move the crane back to avoid being gassed. Put the ladke on the ground and the helper hooked up the two cables, reinstalled the ladle in the frame of the car. Then the car was put back in service. Hard to believe we did crazy stuff like that.
Did the helper use some rod tool to handle the cables?
when the front broke loose, it looked a bit like the doomsday machine from Star Trek.
Surprisingly, very entertaining. "Deskulling" is such a descriptive word to describe it.
All that terminology is a deliberate choice
This reminds me of my Uncle who was actually a Fractum Model 100. He used to take me to work and deskull hot metal all day until he was sold for scrap metal in 1994.

When I was a teenager working the Homestead mills in the 50s, we didn't have impact hammers, broke the slag by hand with a 5 lb hammer and cold chisels. "If you get burned, you get burned" the foreman told us.
Damn that's scary
Do you know why it is necessary to break them at all?
Are they not much more manageable and portable as a single giant rock?
@@Hust91 they crush it up cool it down and reuse it. Or sell it to concrete plants.

@@jerrykinnin7941 Ah, so the slag isn't just waste it has some value still?
Thank you for your answer, I appreciate it.
And honestly, we basically made robot giants to help us do very specific stuff. Or rather, found ways to make ourselves robot giants. It is incredibly cool.
I hail from an old steel & coal town, used to be iron, limestone & coal area. Here they started small in the 1700s and by my time, the slag heaps had become mountains. The slag and coal wastes, were simply hauled up to the tops of the ‘tips’ mountains and added to the top-sides of said mountains. Some would slide down and some would stick fast. It takes a born ‘n’ bred local, to be able to look at a mountain and tell if it’s a natural mountain or a manmade mountain or a bit of both.
Slag was often poured into earthen pits and left to cool into blocks. These blocks are typically 4-5ft. long x 1ft. high x 1-2ft. wide. They were used to build walls, where the strength of stone was needed but the looks of brick was not required. There are still walls made of these blocks, they made good retaining walls. Typically held by rough ash mortar; as suggested, they were used where a strong structure was needed at a very low price. Though I takes a crane to move them.
I'd love to see some of those walls! Can you point me anywhere?
@@weatheranddarkness - Those that I know of, have become parts off privately funded home builds. They’re mostly grown over with ivy/creepers or have been rendered over.
When I was in my early teens, me and my friends were on our way to some waste ground. This entailed climbing down or jumping off one such wall. The wall must have been well over 100yrs. old at the time. The rough ash+lime mortar was crumbling. One moment I standing on the wall and the next, the top of the wall slid, sending me into the brambles below. The brambles broke my fall, which was good if a little prickly. Much to my friends’ amusement.
However, before I could extract myself, the rest of the wall collapsed along apx. 12ft., (3.7m) burying me in the process. Broke off the end of my left fibula and luckily, a block rolled over my head while being partly supported by moving rubble. That one just broke my nose… could have been worse. My friends dug me out with the bare hands; and a couple of lads on their way to play tennis, bundled me into their 1960s Mini and took me home. Another trip to the hospital for me from there. Most of that wall still exists but has been rendered over or buried by garden make-overs, (the houses weren’t there in my teens).

No, the exact opposite, in fact.
not really though, its still red in the middle
If it is blast furnace iron slag then you're in the money! Allow it to cool, pulverize it, crush it, grind it, and mill it until it is as fine a baby powder or bleached white wheat flour powder. Mix an equal proportion of slaked lime powder with an equal proportion of blast furnace iron slag powder and an equal proportion of clay powder. Mix and then add water after it has totally blended together while continuing mixing it. And add some sand and gravel. And you got a modernized version of Smeaton concrete. The original Smeaton cement foundation in England facing the continous pounding of the Atlantic ocean is still intact and as food as new after almost 120 years of service as a lighthouse. The lighthouse has to be dismantled and place further inland because the natural rock formation is being worn away by the Atlantic waves but the Smeaton cement foundation is still as good as new and virtually unaffected by the corrosive seawater itself. But no one has ever tried using steel slag as part of the cement mortar and concrete mixture. www.centuryhouse.org/Next/wp-content/uploads/2015/01/2006summ.pdf

@@venomsoul1147 For the last 26 years, I have been in the company of the RMS Stargazer. The Stargazer and I started our journey together in 1996. She started her life with me as a 1997 jeep Wrangler Sport, convertible. If ever anything could be a friend, it has been Stargazer. I have been through two careers, 10 friends, three homes, and various economical levels in life. I lost my home this January of 2022 in a fire. The Stargazer and I spent three nights together because I had nowhere to stay. All that was saved from the fire was what was Stargazer and me. It was a chest of tools, a length of nylon rope, a shovel, duct tape, plastic bags, crow bars, and my five work uniforms. Work dismissed me until I got my house in order because I was placed in a hotel very far away. During my hotel residency, Stargazer stopped running for the first time in our life together. For awhile, I thought of calling a tow truck and ending our journey together. But with nothing else to do at the hotel, I took off the wiring harness, (no easy task) and started repairing it. It took over a month to remake the wiring harness. It was a labour of love. Early July, I reinstalled the rebuilt wiring harness and Stargazer came back to life. She ran terrible due to the damaging voltages that surged through her when she went into a coma. But I lovingly kept repairing her. Today, she runs like new again. She has been with me through so much. No human, "friend," could ever be so wonderful and loyal. I love you Stargazer. I love you forever.

Just going to take an uneducated guess here:
I'm guessing the slag pot is the train car - it's used to carry the unwanted (non-metallic) leftovers from the smelting process. The Fractum Model 100 is a tool for breaking up the chunks, as it would be easier to move small chunks of slag (e.g.: use a regular front-end loader). Deskulling is the process of emptying a slag pot where things have already cooled to the point of where they aren't easily removed from the slag pot.
That's just a guess, though.
Joel Bennett it doesnt looks like an uneducated guess
I work in the agriculture industry, so I'd say it is a pretty uneducated guess. :P

When you smelt iron ore the melt separates into two parts: iron and lava rock. The molten iron sinks to the bottom of the melt and the molten lava floats on top. The lava is a waste product and is either skimmed or drained off the top of the melt and is removed for disposal as slag.

At my previous job they had this underground pits where the crane dumps orange hot semi hardened slag in. Then they lower the lid like a toilet seat, and spray water from the lid and suck out the steam through the chimney through an underground tunnel. The temperature shock turns slag into loose rubble and sand, then they use an excavator to manually scoop them out into a truck. Then it gets sent to a yard where they run it through a conveyor that separates still usable iron out and filters the rest by size. Much of it done without external contractors. Really precarious builds, but they work lol. Obviously nobody calculated anything so from there we do continuous adjustments and improvement such as hand rails, making walkways stronger, adjusting the angle of the mesh, etc. But theres this crazy situation on the vibrator feeder below a hopper. This one hook on the trough keeps breaking at the exact same spot and people just kept welding on bent pieces of rebar, which then breaks again, just like the original hook. At least 4 broken off bits of the same design welded one atop another, yet nobody thought maybe they should do an upside down U shape or just try something else so it doesnt keep breaking. Anyways idk what they do with the slag but the dust and skull with iron in them gets fed back into the furnaces.

It would only take a couple days. The outer crust acts as a heat sink instead of an insulator. So it is actively drawing out the heat. You can see how thick the crust was already and that is just after a few hours.
It's an interesting though. Consider that earth is somewhat similar to this slag lump, except about 4 million times larger in diameter (assuming 3m diameter slag) but earth is still glowing hot inside after more than 4 billion years.

Slag is the impurities from the steelmaking process. This pot was where they transported the slag in. Now they dumped it out, along with the refractory lining of the pot, and are breaking it up so it cools. Slag can be recycled into road materials or other usual when it is cooled and ground up.
