I use that refractory cement. It will crack after thermal cycling but then so will your bricks. Time is different because someone doing 10 smelts or forgings a day will hit limit faster than some one doing 2 a week. By then you should have made your money back though.

Great process guys! Tons of information. Didn't know you could cut the bricks with a handsaw.

Nice simple build, very cool! A couple of suggestions: don't rely on those firebricks as you innermost insulator - they're very energy inefficient. Coat the inside with 1" of kast-o-lite 30 li plus, then add 2" of refractory wool, then finally coat that with a ceramic heat reflective coating like itc 100 ht. it will increase the costs by alot but your setup will heat much faster and function much more efficiently. it will give you big savings on electricity costs in the long run.

Super neat little furnace. I run gas and have been considering a small electric kiln for heat treating and maybe even melting. Just a note - machinable aluminum alloys aren't always the best cast aluminum alloys. You might take a look at something like A356 - see how your 6061/etc stacks up in comparison. Usually you just need to add some other scrap that's higher in silicon (pistons, wheels, etc) to bring it up to a good cast spec. 6061 tends to be highly porous and just not behave very well when melted. Somehow a bit of silicon helps it flow better and avoid accumulating bubbles of gas. Keep up the great work!

A356 is commonly found in cylinder heads btw. Suspension components tend to be forged. I'd suggest checking out Paul's Garage here on KZread (he has a wicked discord server - crazy helpful folks!) Casting has been loads of fun and recently, profitable. Just wait until you see aluminum bronze though... Lol.

It would be nice to get some info like current draw, Max temp, how to control temp, etc. Could this be done with IGBT FETs? Hmmm. Do the coils burn up?... Guess I need to try this and make a vid.... Solar power induction foundry/forge.

Yup that absolutely correct!

Do u have to use the fire bricks. Could it not be made from scratch. Using plaster Paris. To make the mold. Because those firebricks are hard to find and expensive. With the same electrical parts. Could it be done the same way like how they make gas Melting. By using a gas tank./metal pot. By Adding mesh and plaster paris to make the inside part. And run it that way then start it up from there . All budget friendly for consumers.

Does it have pre-built wired up electric power supply like those selling by itself. No full furness. Just the box that u build with all the small parts to make it work electric. The furness build is easy. The hardest part is the wiring.

Nice build guys... well done. I am being picky but this is what looks like from a professional. Foundry is the organisation or business that does the casting. They own, smelters and furnaces. You built a smelter and run a foundry. Like a brewery and a still... like that. Also you fused mild steel with the TIG instead of adding filler rod? Why? Its a way better weld when using filler rod. That is why its used. Did you cover the terminal block and exposed wire on the side you didn't show when it was operating. That would have been live and red hot! What was your solution for that?

@IMEEMADE

2 жыл бұрын

Thank you for educating us! To answer some of your questions, we often use autogenous TIG for non structural builds like the angle iron around the smelter. It's just a structure to keep the fire bricks from getting ruined during transport/storage so we felt it was just faster/easier to forego the filler. But you're totally correct that adding filler is always best. As for the terminal block that's exposed, to be frank - it's still exposed 😅. Our thoughts have been to make a composite cover of sorts in the future and also add a reed switch to the lid as another user mentioned so it cuts power when opened as a safety feature. Still need a lot of improvements, so we appreciate the advice!

We're made it right at $200. More than half the cost was from the insulated fire bricks since there were no local suppliers and we had to get them shipped during the beginning of COVID shutdowns 😅

So I've finished and tested mine, but I'm have horrible results. I'm using the same bricks, resistance wire, shape and other components to make sure mine worked correctly... BAD NEWS:::. IT won't heat up high enough to melt Alum. So wasted all that time and money.. The PID controller is set at MAX, but the probe only shows a Max temp if 552C. With the Lid closed. Alum needs 600+ degrees Celsius too get to. Liquid stage. Thid DIY unit can't get higher than. 567c. To try to connect design flaws I've actually reduced the length of the resistance wire which based on my calculations should increase the overall temperature however I've only gotten to 571 Max.. This of course was after I shortened the 70 more 9 ohm by forget now wire length I initially cut his who based on your recommendations. I chopped off about two-and-a-half feet worth of wire and it is getting hotter this time but still not hot enough .
