Principle of the induction heating technology
1) can make metal objects instantly heated to any temperature required， including its melting point;
2) need not be like other heating methods that produce high temperature， first and then go to the heated metal object it heating， can be generated directly in the metal Temperature;
3) not only can make a metal object overall heating， can also be selectively localized heating of each part;
4) is a kind of heating way of revolution， the same is electric heating， but it can save electric power forty percent than electric oven.
This is a powerful advantage of high-frequency machine， medium frequency machine.
