Microwave oven metal foundry? Answered

Can you melt steel scraps in a heat resistant pot hot enough to mold or pour with a rewired MOT? What if you put multiple MOTs in series/parallel? how could you make into three phase (i want to know weather this works or not)?

You can melt iron in an ordinary microwave.

better find something more powerful else it wil start melting the outer surface slowly resulting in small explosions. and something like red hot metal shavings coming out. very dangerous. if you use a very powerful microwave oven it won't be the case but take precautions

I'm not using a microwave. If you read the question I said with a rewired MOT.

oh. just put 4 of em in parallel. make sure that they have the same primary.(after modification secondary will be used as primary). so that they share equall power. and also ballast them. with another MOTs

You need a three phase supply.

If you haven't got one coming into your house, you can't make one.

You want to build an arc-furnace, it's possible but hazardous.

And there's the method where you have a heavily watercooled pot and melt metal into the bottom of it with an arc. The "welding rod" is made of some crappy metal, you pour flux down onto the arc, and the flux takes off all the crap, the resulting metal that falls through the flux is extremely high quality.
