Induction heater, also known as induction heating power supply, also known as induction heating equipment, is a general term for all heated workpieces involving induction heating, including: induction heating power supply, induction heating equipment, bearing heaters, bearing induction heaters, and industrial The basic working principle of the induction heating power source used for heating, evaporation coating, and copper brazing after the pipeline is preheated is to use alternating current to generate an alternating magnetic field. This alternating magnetic field causes eddy currents to be generated inside the metal conductors current), so that the metal workpiece heats up rapidly. Generally speaking, the effect of heating is determined by frequency, current, and magnetic field.

In the process of induction heating, only the metal part of the heated workpiece increases in temperature, and the induction heater itself also has heat. Most of the inductors need to be cooled by cooling water during use, and the non-metallic part of the heated workpiece does not generate heat. .

All metal workpieces can be heated with induction heaters, such as cast iron, motor short-circuit rings, automobile hubs, metal bars, pipes, bolts, large turbine bolts, wind turbine blades, bearings, gears, pulleys, couplings, etc. .
