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.

    Good to finally see some of Sch3matic’s projects on here. He’s certainly capable enough to be a hack-a-day’er :D

    Wow – crank it up.

    he sounds like dwight from the office

    cool project..

    Looks like something you’d find in the unabomber’s shack or a drug maker.

    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.

    Hot! Quite literally, too!

  7. bjonnh says:

    Is the salt used in the video Potassium Chloride or Sodium Chloride ? I see he tried both

    This project is wonderful ! A complete work with precise explanations. Great work man!

  8. NICE HACK… this is what Hack-a-day is all about!

    Great job Tim… if anyone is interested, I think Tim is looking for people to help test prototypes: http://www.abymc.com/forum/viewtopic.php?p=7481

    Looks like a product who can put to market as it is :-) Good hack!!

    Hahaha! Tim! This is great! You’ve been working on this furnace for what three years or so? I’m so impressed by how far it has come! Great job man!

    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.

    lab of my dreams…

    i wonder what that huge inductor will do to his power factor

    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!

    i’m sorry, maybe i’m seeing things. is the power supplied by AA batteries?? O.o

    I base this on my CD4011 and LM393-324 to help guide the agency in the map right here I do not know what I base my vessels to which wire on the map

    That’s great. Is it piratical to use an induction heater to heat your home
