Induction Furnace

induction furnace

[Tim Williams] made his own induction furnace. A copper tubing coil forms the primary winding, as the material to be heated becomes the short circuited secondary. The load material is subject to high power magnetic fields operating at radio frequency. The rapidly changing field induces current flow within the material, creating a great deal of heat. The brute power required a cooling system to match. In the video below, the induction furnace can be seen melting common table salt.

  1. This gent is a true engineer, I haven’t seen an understanding of electronic principal like his in 20 years, puts me to shame. love the attention to the nit picky little details.

  2. Oh my! I believe I’ll stick with old fashion fire. :) Though it was interesting read about the project. Thanks to the Designer/author for documenting and posting it to the web.

  3. This is SWEET- in the video, it’s at 1500 Degrees. Can he make this thing get up to 5,000 Degrees F? I’d love to make my own crystal melting furnace by adapting his work here, as I can’t afford a commercial unit, being a tinkerer. I’m talking about melting ruby to make my own bearings. Any ideas?

    Sentiments seconded from others- this is an INCREDIBLE hack, monumental. These things can practically melt anything, and are complex as hell, or so I’d thought- I never imagined I’d ever see someone make their own. This is absolutely incredible!
