40kw 7-40kHz 300c Induction Heating Machine for Annealing

Electromagnet Induction HeaterInduction heater is also called induction heating power supply, also called induction heating equipment. It is a collective term for induction heating of all workpieces being heated, including: induction heating power supply, induction heating equipment, bearing heater, bearing induction heater, and industrial The basic working principle of the induction heating power supply used for preheating pipes, evaporation coating, and copper brazing is to use alternating current to generate an alternating magnetic field. This alternating magnetic field generates eddy currents (eddy currents) inside the metal conductors. current), so that the metal workpiece quickly heats up. Generally speaking, the heating effect is determined by frequency, current and magnetic field.In the process of induction heating, only the metal part of the heated workpiece is increased in temperature, and the induction heater itself will also have heat. Most of the inductors need to be cooled by cooling water during operation, and the non-metal part of the heated workpiece does not heat up .All metal workpieces can be heated by induction heaters, such as cast iron, motor short-circuit rings, automobile wheels, metal bars, pipes, bolts, large turbine bolts, wind turbine blades, bearings, gears, pulleys, couplings, etc. General Specifications:Power Supply Range: AC~ 3 Phases, 315-445VFrequency Range: 50-60HzPort Types:Programmable Digital Input, Switch Relay Input, Variable Gear Input, PLC, Temperature Controller "0-5V" or "4-20mA", K-thermocouple Input.Features:Overload Protection120% 5s; 150% momentaryStarting Time98%Efficient Power>90%Designing Life Period50000 HoursProtection Inspection
