I worked at USS Blast Furnaces as a MTM. We were not allowed anywhere in the BF area without a CO monitor displayed/attached to flame retardant clothing.
iron ore is reduced in the hot carbon monoxide atmosphere (to impurity rich pig iron) .. it's an exothermic reaction .. it's more about reduction than melting of the ore. Also in modern steel-making the pig iron is not "remelted" but rather transferred in it's fluid state to a converter where impurities are blown out (and alloying additions added) through the introduction of oxygen and ferro-metallic alloying substances. Ferro-chrome, ferro-vanadium, ferro-silicon.
These are critical in case there is ever large scale war again, hopefully that day will never ever come but Russia and China are unpredictable so keeping these furnaces going is very important to being able to defend against them While the day to day job might seem just like another day at work, it keeps a critical part of the ability to scale up military production in case of something bad. Unfortunately large mills were lost in the last 20 years due to artificially cheap prices of steel from China but government policies have come in to block that and it has helped allot in the USA and also Japan and South Korea. Not sure about Europe but hopefully it is the same. These are critical industry and must be protected.
Ive seen a number of videos on rebuilding blast furnaces, super interesting for sure. There's one here on YT about a rebuild of Bethlehem furnace, quite the process for sure. One thing I've never seen or heard though, that's the start up of a cold or rebuilt furnace. Once in operation, it's sort of self sustaining, coke, limestone and ore go in the top, liquid iron comes out the bottom. Reclaimed and fresh heated hot air is forced into the furnace, the coke and limestone burn/react and melt the ore. How is the process started in a cold furnace?
On start up the blast furnaces which I worked on were lit by a bonfire which had been built in the hearth once alight coke was added and gradually the furnace was brought back on line. For the first three to for days the area was restricted due to the possibility gas been present this is because the new refractories lining the inside of the furnace need to fuse together and become 'gas tight' The last furnace re-line I worked on took 34 day's and was carried out by hand picked team.
Great to see Western manufacturing still thriving in Germany, wish the US would have some again instead of shipping all of our manufacturing to people who get paid nothing in the East and in Mexico.
America's competitors make high grade low alloy steel in Japan and South Korea, alongside these German furnaces. They earn pretty decent wages. The problem isn't the wage competition. It's Cleveland Cliffs and US Steel being more focused on shareholder returns than long term improvements.
Wrought iron is very low carbon iron with a melting point of about 1,500 C. The furnace produces high carbon pig iron for use in converting to steel. Pig iron melting range is 1,000 to 1,600 C depending on carbon content.
You need to overheat the pig iron (4,3% Carbon content gives you around 1300 C melting temperature) so it doesn't solidify during transfer into steel mill, also that heat is used to help melt the steel scrap that is casted into oxygen converter.
Gauntlet usually at least about 80 %, if not more. Others might be mostly of polish or Turkish origin, but even those live in the Ruhr areas in second or third generation already. A lot of people in the Ruhr area actually have polish ancestry.
This is why our country is falling behind. People are so busy dunking on other people that real tasks like materials science and engineering have fallen wayside. Why don't you gripe less and advance yourself.
Rainer Klock *is* Hank Rearden - from Atlas Shrugged! Highly recommend that book for anyone who loves steel, industrial production, science and rationality as opposed to superstitions, and government cronyism.
This hasn't aged well. Fuel shortages have shut down almost all industry in Europe, including Germany. They might have trouble even surviving the cold of winter. Still want that Green Agenda, Europe?
Everything "fantastic" in this video is completely ordinary and nobody would want to do this, or want this done, if it didn't absolutely need to be done. This isn't heroic. These aren't heroes.
+Dan Hillman he is right. for those of us that work there, its nothing fantastic, its just a job, just using larger scale machines. the novelty of the scale, noise and movements wears off soon enough and it becomes just a job.
You really have to love that kind of work and make a lifestyle out of it. It's not a job. It's a way of life.
It releases carbon monoxide, which is bad for the health and people who work near there are affected.
I wish I had that kind of a job instead of sitting and working on the computer all day
@@ahwabanmukherjee5065 yeah you really gotta love that kind of work and make a lifestyle out of it.
these are germans, they born with a engineer certificate

Those ladles emit so much heat. I must have been stood a good 20-30 meters away from one, I could still feel the heat
To see the inside of that blast furnace with all the tiles is very cool. Not something that happens very often.
Just got to watch a full re-line . All of the brick work is amazing .
I agree.
Keep thinking his name is 9 o'clock
It is

You are very smart indeed. xD I guess I'll need some knowledge too for my test next week pft ;p
I thought the reduction of iron oxide to iron was an endothermic reaction
Big words Bro big words you're smart man
@@markschenher4559 No because the carbon impurities in the ore and the iron react with oxygen to produce CO2, this reaction gives off heat.
"transferred to its fluid state".....yes, by...melting it....
the proper people brought me here
Same
Who? This was awesome.
@@TheSparrowLooksUp type in the search bar “the proper people”
One year later they are still bringing people here
He’s not lying . No 2 days in the BF are the same . I’m proud and lucky to work with the team that I do
This guy loves his job. good for him
Alfred Krupp is proud
Engineering is magic
Thyssenkrupp. Engineering tomorrow. Together.
I wish to experience this one day
Why isn't the title of the video called Rainer Klock?
Dr. Thorsten Wuerst at West Virginia University sent me here for IENG 302: Manufacturing Processes

These blast furnaces become critical targets during a major war

In days gone by with wood kindling apparently

Hi thanks 🙏 for the great 👍 videos to day great to see up grading a blast furnace
Ok🦍
No skips conveyor feed wow
I stood inside the blast furnace at Dorman & Long, Acklam works in the early sixties. It was really spooky, surprisingly cold and damp.
I knew Europe played Protoss
you must construct additional blast furnaces
Great to see Western manufacturing still thriving in Germany, wish the US would have some again instead of shipping all of our manufacturing to people who get paid nothing in the East and in Mexico.

"Europe’s Biggest Blast Furnace"
Europe's LARGEST Blast Furnace. FTFY
He has a job.
Blast furnace handle wrought iron only which has a melting point of 1,200 - 1,250 °C only. Then, what is need for 1,450 °C?
Wrought iron is very low carbon iron with a melting point of about 1,500 C. The furnace produces high carbon pig iron for use in converting to steel. Pig iron melting range is 1,000 to 1,600 C depending on carbon content.

I thought the 'House of Krupp' was disbanded?
happy You for this job😨😨
Kitno hard work hai
0:13 a little close ain’t it
Salaam to everyone I can tell u from experience after a days work in a foundry I sleep like a baby so cook butt the wages wer so good in 1978
you
cand reduce the energy bill by using regenerative braking like sistems
at the heat lost in furnace ...there is a lot of heat lost ready to be
use
👌🏿🦍✌🏿
i loved it
Cool
Very good
And zhen, once ze job ees finished ... ve dance! (cue techno music)
and more than iron is needed to make steel
... all U need is FIFTY FOUR.
just watch people walk around this thing coz its abandoned now
Really??
@@fitrianhidayat nope. This one is still going strong
What percentage of the workers are actually German?
Gauntlet usually at least about 80 %, if not more. Others might be mostly of polish or Turkish origin, but even those live in the Ruhr areas in second or third generation already. A lot of people in the Ruhr area actually have polish ancestry.
GEOMETRY DASH BRING ME HERE
All the coke and slagg that's going to be pumped into this large scrubber..
Lava
I didn't see any pink/purple haired feminists working there, weird.
Hmmm.... they must be camera shy
Epic comment 😂

Not weird, they don't even know what a kitchen is. 🤣

Soon this stuff will go to China
I doubt it, the unions in Germany don't seem to have an adversarial relationship like in the states, the work together to maintain the business going
I think you are right, can you write the name of steel making plant from China?
the biggest in Europe is Taranto- Italy
Its probably the biggest Steelplant, but the biggest Blastfurnace in Europe is the one in the video. Named Schwelgern
Trying to correct a professionally made video never ends well, sinistra.
Really????

Germany has a well known history of burning and ovens and furnaces.

neanderthals
I'm here from south Wales Tata steel port talbot, unfortunately now though they have closed both furnaces die to building a new electric arc
