The medium frequency furnace is a power supply device that converts 50HZ industrial frequency AC into medium frequency (300HZ to 1000HZ). The three-phase industrial frequency AC is rectified into DC, and then the DC is converted into adjustable medium frequency current to supply the medium frequency alternating current flowing through the capacitor and induction coil, generating high-density magnetic lines in the induction coil, cutting the metal material contained in the induction coil, and generating large eddy currents in the metal material.
