i need to build a induction heater it needs to hit 2000 deg C or 3650 deg F PLEASE HELP!!!
thanks

Search internet for "Thomsons coil"...
But beware! In case you are not sure what are you doing with it.....you may burn yourself and a house!
I did that once that's why i admonishing you now...

induction heater

maybe I need to provide more information I have little knowledge of electronics I have fair manufacturing capabilities and need an induction heater that can heat a bulk of 2.5 pounds or more up to 2000 deg C maybe higher to be safe I have 220 wall outlet and im working in an industrial zone in a cement building fire safety is not a problem I have keep the price down thank you for all your help

Maybe is not enough for you but...

induction heater

i have found an induction heater i think its the best one i found on the web its 10 kw i think but i was hoping for something better like 30-50 kw i still would need help to understand it all and sorting it all out like a parts list i wish it was broken down a little more

HOLY S*@T 30-50KW from 220VAC?? I think you should be looking into a three phase 100A system. If you try to use a normal mains with that you will nuke your fuses or melt the wires in the walls.

Seriously, induction heating is NOT for beginners, you need to seek a professionally built unit, unless you enjoy hospital food.

Once the heating starts, things get hot VERY FAST and without a proper build, things you had hoped wouldn't can, and usually do!

Heat treat ovens can do that. You have to have special elements to get that kind of heat and not burn out. Heat treat ovens are made to harden and temper steel, they have thermostats to keep the heat at a constant temp, that is just my opinion.

induction heater

i am backing down on the 30-50 kW. i am going for more 10-20 kw. tomorrow someone is giving me 3 (3phase) conveters, and 2 280 amp arc welders. im not sure but i think i can get 5000 watts from each arc welder transformer. if i can run them together i will have 10000W with some loss maybe more, and i think the 3phase conveters might have big transformer im not sure i have never seen one befor but there good and working i could still use some help i have not a clue what im doing. i found some caps for the work coil. i will have to buy 200-500 there 17.1 amps rms each and 0.1 uf 250 volts so that all for now thanks for telling me i was out of line with 30-50 kw now i see

Just curious....; for what purpose do you need such "beast"?
You wanna start melding people arround..?!

induction heater

i am making sulfur dioxide on the low side of the temp, and on the high side i am going to try to make nitrogen oxide. i will make other things maybe a plasma, and with the help of a carbon arc i can make pure Silicon. i made some MgO that i need to purify. i also make chlorine and sodium metal, and anything else i can think of doing with it

[ivconic]

Ok...than go for it!
Regards!

It is best to buy a good induction heater. Perhaps, a used device. It is basicly a high power oscilator (Many Kilo-watts) with an external water cooled coil into which the subject is inserted.

How much?

[Overtheedge]

Keep in mind that induction heaters operate at a higher frequency than power mains. Picture a radio transmitter with the material to be heated inside of a watercooled circular antenna. Arc welders tend to operate at 50-60 hertz.

Basic principle is eddy currents induced in the material by the antenna. Lenz's law covers the eddy effects with a nice dose of Hysteresis adding to the eddy current heating effects.

The other thing to keep in mind is the amount of heating available. Kilowatts to BTUs needed to achieve a melt for a given quantity of metal. More insulation helps, but actual power available determines speed of melt.

Got interested in induction heating for aluminum cans for recycling. Until I realized the power requirements and hazards.

Don't overlook microwave ovens for small quantities. Saw something on the web about experiments with household microwaves and metal melting. Lost the site addy when the computer failed.
