Melting cast iron at home - Element Cube Collection (DIY)
Просмотров 25 тыс.Год назад
We have reached the seventh cube for the element cube collection: Cast iron! Made from a pair of disc brakes, which was quite a challenge to get melted due to cast iron's high melting point. As something new the cube is engraved using electro etching, where an electrolyte of vinegar and table salt is used. The power supply is set to 12V and draws around 500-1000 mA. Please remember good ventila...

Просмотров 76 тыс.2 года назад
This series explains how to build an electric kiln/furnace/oven, which can be used to melt metals, fire ceramics, burn out casting moulds (and make marshmallows). In part 1 we start by cutting an old almond oil drum into the bottom and top lid pieces. Then fire bricks are cut to the correct shape to form an octagon shape, and finally they're mounted in the oil drum. The silicate insulation mate...
Casting a Yellow Brass Cube - Element Cube Collection
Просмотров 4742 года назад
Next cube to be added to my element cube collection is Yellow brass, which is a common alloy consisting of 33% zinc and 67% copper. First the copper is brought up to its melting point around 1089°C, and then the zinc is added. As seen in the video; the copper is too hot which causes some of the zinc to burn away (the green flames and white smoke). The first attempt results in a cube with a big ...

HI! What kind of firebricks did You use. What are the specifications. K23 or K26 or some different type JM23 or JM26 maybe?
Complimenti. Seguo da Roma questo importante e bel progetto. spero che tu possa continuarlo a migliorare. Grazie ciao Paolo
This is pretty damn cool, I might have tried making my own iron in the future but it really looks like doing this alone mighe not be a very smart idea lol. Possibly if a smaller scale is possible to make something that weighs only a few kilos, but you do need people around to prevent fire spread.
If you are an electrician, this is a piece of cake. If you are not, please do some real electricity courses before attempting! Regards: electtrician.
Sorry, but there is a problem with this type of lid design. When open the hot underside of the lid is facing anyone trying to access the inside of the furnace. At higher temperatures in particular this will make life difficult. This is why my furnace lid lifts slightly and then swings to one side, the hot underside is thus only pointing harmlessly downward and not towards me. This is just as easy to build as your set up here.... Martin PS. What holds your elements in? My attempts at an electrical furnace (3 phase 25 amp variac controlled) had elements just sitting in simple grooves and on cooling down the contraction of the elements slowly (over a few uses) pulled the elements out of the grooves.
HI, I saw your videos on building the oven, thank you very much! the tutorial is very well done and detailed. Now I want to build one too and I'm looking for all the necessary materials. I found the bricks of 26T refractory material, but I can't find the tiles you used for the lid and the bottom, 50 mm high. Can you advise me where I can buy them? I imagine I will necessarily have to use 26T or 26J material and not a common refractory material. I also ask you, can you share the files of the shaped and processed bricks and the technical drawing of the oven? do you have a general list of the materials used? Thanks so much again
did you write up a kiln heater worksheet in LaTeX?
Well done very informative video . Question > how you knew what temperature you will reach with such element length , power ?
Hello, is it possible for this kiln to work on Single-phase current? And if i want to use the maximum volume and put on one or two more Rows of Bricks, could it be more kW on Single-phase current and is this insolation suitable for this?
Just an fyi based on my local electrical experience(s), when dealing with mains voltages and current above 5amps you should only use mechanical connections to secure conductors throughout the circuit as solder can & often will soften under load and break free from connections. Take it or leave it, just my 2 cents on an otherwise beautiful build. My hat is off to you sir! 👏🏻
The end of flexible electrical wires shouldn’t be drilled. Leave them straight and put some wire end ferrules on it. Also when you put more than one cable in it. Otherwise it might get loose due too heat expansion
May God bless you for this wonderful information
Great
R of wire change with Temp, it is not constant.
What is material for the pure SiO2 glass melting mold, for temperature ~1700 C degree?
Very nice detail with that spring. But will the lid still close and seal properly with that big spring pulling and trying to open the lid?
Great follow up video. Clear descriptions and it was sweet to see the orange flow when you posted it on😊
Excellent description and pace. Godt gået😊
did it melt from the amperage or from the heat from the kiln
I appreciate what you are saying here. I just tested my kiln and at 240v and 20a with his calculations I can only get my kiln to 631 degrees *F. Any suggestions on how to get the temperature higher?? I followed his instructions to the letter. I’m very confused why I’m not getting the same output. Any help. Would be appreciated. Thank you

Is there no reason to clean it a lot? If you soak it in a light hcl solution before melting would it be a higher quality mix?
Impressive...
😁😁😁🙄👍🏼
You measured cold resistance... Resistance at >1000°C is much higher, so less current will flow. You will not have the desired power. The difference is big. Much bigger, than one would think at first.

@@ArchangelZero2012 Well... I have to assume you don't have the electrical training necessary to do this safely. Be careful, but you are on your own risk. 631°F is what? 300°C? That sounds way too low for just a temperature dependence in resistance. What temperature did you try to reach? Is the resistance at room temps where you expect it to be? I would suggest to measure the actual current consumption, cold and at the max temperature you get. And work your way forward from there. I think you have more than one issue at hand.
This is seriously the best kiln building video on YT.
except he never finished?
@@MattRix Yeah... found out soon. -.- Still, I will copy that oil drum and other design features.
Is the part 5 video coming anytime soon?
In fact, you could use only silicate to insulate the cover instead of bricks. This part is not exposed to damage and requires the best thermal insulation.
do you say that would be enough to isolate? I'm also designing a front-opening oven following these instructions, but I'm having trouble finding refractory tiles of the 26T or JM26 composition.
Would it not be prudent to measure the resistance prior to coiling the wire? That way you don't need to be so careful not to let the coils touch while measuring. Thanks for the video!
NZ Steel mine black sand from the North Island West Coast at Waikato Heads and then use it to make steel products. Further South on the same coast at Tahoroa it is mined and and pumped as a slurry to a pick up buoy where ships load it for transport to Japan etc.
Leaded tin bronze is the most yellow

Now it makes sense! my mom had this “beach”-saying: “Once you go black, you will never go back”. She is right afterall! Black is much harder, tougher, and can withstand a multi-hour “warm-up” - and still keep on hammering and smashing the bloom! For hours!!
You promised me you would be back soon! Why are you not back?
I really like the way you presented the information about this build. I want to make an electric aluminum smelting furnace along the lines you have made. I wanted to make my furnace capable of just pouring the molten aluminum directly into an ingot mold or a casting jig. Ideas? Thanks, Dave.
Is there blue print of material and design of wiring
Thank you for the video and answers in the comments
couldnt you just take a few cook range 240v heater elements and save yourself all the calculations and cost , these can be found anywhere , thx for sharing ! nice job !!
Dear sir Would you please send me a file with measurements of hinge between bottom and top of the kiln
Tusind tak for videoserien! Den har været uvurderlig til at foretaget DIY reparationer af keramik-ovne!
Таким же способом пробовали железную руду делать из золы. Рабочая схема.
Just want to add that I really am enjoying this tutorial series. Well done!
would ceramic fiber insulation blanket protect your control box?
He is playing Minecraft java edition in real life brah
Can you tell us why is a thin wire gauge not recommended?
That’s pure iron ?🎉
Also I want to add he engineered this kiln very well.
This guy is really smart and good with his electrical. Awesome video! Thanks!
