Hey Neil, thanks for the advice. Will your induction forge reach a temp hot enough to melt steel? Are you using this 15kw model that I keep seeing everywhere?

I was looking at one of these: https://www.aliexpress.com/item/15KW-30-80KHz-High-Frequency-Induction-Heater-Furnace-LH-15A/32334611089.html?spm=2114.search0104.3.1.19133ac8aaB5xZ&ws_ab_test=searchweb0_0,searchweb201602_5_10065_5024915_10068_10130_10890_318_10547_319_10546_10548_317_10545_10696_450_10084_10083_10618_452_535_534_10307_533_532_204_10059_10884_323_325_10887_100031_320_321_322_5728515_10103_448_449_5728415,searchweb201603_35,ppcSwitch_0&algo_expid=74466d20-3f4a-48f0-8c05-cfa190cfc028-0&algo_pvid=74466d20-3f4a-48f0-8c05-cfa190cfc028&transAbTest=ae803_5

It is 110v/60hz, 15KW, 600amp max current. I think there is some math involved to determine the maximum coil size. Ill try to find out more tomorrow.

Thanks!

OK; unfortunately all the folks I know making that sort of thing use propane furnaces...I'd direct you to the Metallurgy lab at my local university, (north habitation) but I don't know if you are even in the same country as I am.

I'm in Ohio. Yeah I did see a lot of propane furnaces set up for this. Propane where I live is pretty expensive though and since i'll be working in the garage over winter, I was hoping to find something a little less unhealthy to inhale. I saw a few videos of people melting steel in crucibles placed within the copper coil of an induction setup, but with people making their own custom coils, i'm not sure the maximum size, therefore the biggest crucible I can use effectively. 

I am just getting started in the hobby and hoping to eventually make knives and swords for fun.

I'm not looking to cast, but I would like to melt down old scrap metal bits and mix in other stuff to form my own pucks. I guess i'm trying to find someone that has melted crucible steel in one of these 15kw induction forges and how much can be done in a given cycle, and also how long it takes. I can't find much about these.

Hey All,

I am looking to buy a 15kw induction forge to help me make blades. It would be my only forge and I like that it can also melt steel down. I can't find a lot of examples, so i'm wondering if anyone knows how much steel I can melt at one time in a 15kw forge? I assume it wouldn't be enough to make a sword with 1 ingot, so I would probably need to forge weld a few of them together.

Thanks,

Max
