Principle of induction melting Furnace : The thyristor medium frequency induction heating power supply uses a thyristor to convert three-phase power frequency AC power into single-phase AC power of several hundred or several kilohertz. The working principle of the intermediate frequency power supply is: using a three-phase bridge type full control rectifier circuit to rectify the alternating current into direct current, after the reactor is flat wave, it becomes a constant direct current source, and then through the single-phase inverter bridge, the direct current is inverted. A single-phase intermediate frequency current at a certain frequency (typically 1000 to 8000 Hz). The load consists of an induction coil and a compensation capacitor connected in a parallel resonant circuit.
Uses of induction melting Furnace: Widely used in the smelting of cast steel, stainless steel or alloy steel, vacuum smelting, heating of forgings and bending of steel pipes, extrusion molding, preheating of workpieces, surface quenching of steel parts, annealing heat treatment, welding of metal parts, powder metallurgy , conveying high temperature working fluid pipe heating, crystal growth and other different occasions. In our factory, the intermediate frequency power supply is suitable for the smelting and forging, hot rolling and through-heat treatment of steel materials such as steel, copper, aluminum, zinc, nickel, gold and silver. It is mainly used in the casting smelting industry; it has the characteristics of convenient control, high efficiency, reliable operation and low labor intensity;
