SRIF has more than 30 years history to research and produce M. F. induction heating equipments. The products form the series which are used in melting, holding, deep heating, quenching etc of spreading all over the ferrous or non-ferrous metals. The products running feature is high stability and reliability, increasing temperature and melting is fast, saving energy is high-efficient and safety is very good. The control system has no contact; all use digital integrated circuit, zero voltage auto scanning to start. Frequency is auto tracked, the control is voltage and current both closed loop system, the leading current angle auto follow the change of adaptive load impedance, the output is constant power.
　　For the high power M.F. equipment, the main circuit is high voltage input and the commutate is 12 pulse wave, so harmonic jammer to power source lessen markedly.
　　The series inverter SCR M.F. power equipment, high power density; there is no harmonic pollution to power source. It can realize that a set of power supplies to dual furnaces synchronously. And the power can be assigned according to need.
　　The power of induction heating equipment: 100～3000kW
　　The capability of M.F. induction furnace: 50～10000kg
