Medium Frequency Furnace

Function:

Medium frequency furnace is a furnace using induction heating effect of material to make the material heating or smelting.

Principle:

It is the power device transforming (50HZ) alternating current into medium frequency rate and transforming 3-phase alternating current into direct electric. Rectified into direct current into adjustable frequency current to supply for the induction coil, and produce high density magnetic lines in the induction coil, and cut metal in induction coil, produce large eddy currents in the metal material, achieved the purpose of heating or smelting furnace for electric furnace
