MEDIUM FREQENCY INDUCTION FURNACE

     SRIF has more than 40 years’ history to research and produce M.F. induction heating and melting equipments. The products form the series which are used in melting, holding, penetrant heating, quenching, and etc. of ferrous or non-ferrous metal. Features of the products: stable and reliable running, fast temperature increasing and melting, energy saving and high-efficiency, good in safety, control system has realized digital integrated circuit without contacts; starting with zero voltage auto-scanning, auto-tracked frequency, both closed loop systems of voltage and current, constant power output.
     For the high power M.F. equipment, the main circuit adopts high voltage input and 12 pulse wave commutate, it can markedly reduce the effect of harmonic component to the power supply network. SCR serial inverting M.F. power equipment can realize that one set supplies power to dual furnaces synchronously with high power density and no power pollution, and the power can be assigned on demand. The power scope of M.F. equipment: 100~8000KW.
     The capability of M.F. induction furnace: 50~15000Kg.
