High-frequency induction heating equipment has been widely used in the province, located in each frequency range 20}} - 450 kHz, high frequency power up to 400 kW. The province's high-frequency induction heating equipment is mainly used in metal heat treatment, 'hardening, through heat, melting, brazing, straight seam welded steel pipe, vacuum devices to gas heating, semiconductor materials refining, plastic heat sealing, baking and purification, etc. . Now the high-frequency induction heating equipment is used to power the province vacuum (launch tube) constitute the core of a single-stage self-excited oscillator to convert energy into high-frequency alternating current high-voltage direct current energy, their tube plate conversion efficiency in general the overall efficiency of the machine for about 75 rings in the goods-sensing device, the device is generally below 50 velvet, water, and energy consumption is very large. Ongoing product prices during induction heating induction heat treatment equipment, in order to ensure the quality and improve the thermal efficiency of the heat treatment, must be based on the shape of the workpiece and requirements, design and manufacture of structures appropriate sensors. Commonly used sensors outer surface heating sensors, sensor bore heating, flat heating sensors, universal heating sensors, special type heating sensor, a single type of heating sensors, sensors in composite materials induction heating equipment products smelting furnace and so on. Induction heating heat treatment equipment consists of a power supply, quenching machine and sensor components. The main role of the output frequency of the power supply is suitable alternating current. Frequency current power supply has two kinds of tubes and thyristor inverter frequency generator. IF current power supply is generating units. General power supply only one frequency of the output current, some devices can change the current frequency induction heating can also use 50 Hz power frequency current.
