Induction heating equipment is a unit converting electrical energy into heat by means of electromagnetic induction. The AC input power (220V/380V/415V/660V, 50/60Hz) is converted into the direct current through rectifier circuit, and then the direct current is changed to high frequency alternating current, the frequency ranges between 5-30kHZ. The alternating magnetic field is created when high frequency alternating current is delivered to induction coil, it penetrates the objects (iron, cobalt, nickel and other metals having magnetic permeability) to allow generating eddy currents. Heat is produced where these eddy currents flow, that is, inside the object. Through the inducting heating process, metals can be heated in a rapid and efficient manner.
