Details
A medium frequency furnace is a power supply device that converts 50HZ industrial frequency alternating current into medium frequency (above 300HZ to 1000HZ). It is widely used in the smelting of non-ferrous metals and ferrous metals. The medium frequency furnace rectifies three-phase industrial frequency alternating current into direct current, and then converts the direct current into adjustable medium frequency current, which is supplied to the medium frequency alternating current flowing through the capacitor and the induction coil. This generates high-density magnetic lines in the induction coil and cuts through the metal material contained in the induction coil, creating a large eddy current in the metal material. The free electrons of the metal itself flow in the resistive metal body to generate heat, thereby achieving the heating of the metal.
