The aforementioned have contributed financially to the continuing triumph of 4hv.org. They are deserving of my most heartfelt thanks.
Hello 4HV. Today, when at a community service event, I had seen a guy forging some things. He was telling me about how this guy made an induction forger, but it was pretty big. I was just wondering if it was possible to create a 12 *12*15 inch size induction forger for small forgings like knives. I was thinking, that because of the need for a coolant, the induction forgers have to be huge. In theory, however, if you hooked up a 220V high current transformer to an induction coil driver, with the induction coils being made from (when it is discovered) a room temp superconductor, or something close to it, would you be able to make something of that size to heat a piece of 4 inch long, 2 inch thick metal to a temperature range of 1800F-2200F?

Many of the induction heater projects on this forum are pretty small sized. Whether they can heat a piece of steel that hot I do not know. For a royer oscillator (zvs) design I think the cooling can be as simple as running water into the work coil and out the other end since the transistors and tank capacitor can be connected directly across the work coil tubing. Check out the Projects section for more info and ideas, I've got to leave at the moment.

This has already been done, and one example of its use is to rapidly heat chains. Just look up 'chain induction heating.' Not too sure on the specifications, but it will heat a large chain red - hot in a few seconds.

Done it. Easily heats a 6" x 3" x 3" block of steel over 2800F to the point it started disintegrating as it turned to liquid. Go here to read about it. You don't need a superconductor or anything fancy. You need water-cooling to keep the work coil and mosfets cold.
Go to Youtube and seach under imsmoother and look at the many videos that include the induction heater for blacksmithing.
