I have a gas cruicible furnace but it wastes gallons of fuel to pre heat for a steel pour. I've been looking at induction furnaces but the $6,000 for one about the size you have is out of the question. Could you make a walkthrough vid of your SMPS and modifcations to handle a coil the size you are employing? Anything at all would be very very helpfull. Thank you.
Very nice! Would you be willing to share details on the construction of this furnace? I assume there is an induction coil somewhere. Is it embedded within the furnace's square block of insulation?
@tzampini Are you an expert on power electronics? an induction furnace is a very difficult project to build. Have a look at my video on youtube " induction heater from scrap electronic parts". This was made from a switch mode power supply I found at the local dump so cost nothing to build.
can you give me info on how to construct one ,

What kind of efficiency/energy use do you see from your furnace? That is, how many Kilowatt-hours do you churn through to melt say, a pound of iron?
My back-of-the-envelope math (which, admittedly may be entirely wrong) says this should be an extremely efficient setup. On the order of .5-1kW/kg.

@JeffreyRodriguez Cast iron takes 4 kwhr to melt 3 kgs.

@BrimstoneMerc The furnace is not mine so I cannot help you.
