Electromagnetic heating, we also called induction heating, is a kind of non-contact heating mode. Its working principle is to convert electrical power into electromagnetic power through circuit control and then the electromagnetic wave the ferrous material converting electromagnetic power into heat energy, so that the heating goal achieved. The traditional heating is a kind of heating, which transferring not convert heating from the fired resistance wires or gas, has a bigger heating loss during transferring process.
Induction heaters are also highly versatile and can be used for a wide range of heating applications, including melting and casting non-ferrous metals, hardening and tempering of metals, and heating of composite materials.
