Working principle of high frequency induction heating equipment

  The full name of the high frequency heating machine is “high frequency induction heating machine”, also known as high frequency induction heating equipment, high frequency induction heating device, high frequency heating power supply, high frequency power supply, high frequency welding machine, high frequency induction heating machine, high frequency induction heater (Welder), etc. In addition, there are medium frequency induction heating equipment, frequency induction heating equipment, the application range is very wide.

  High-frequency high-current flows to the heating coil that is wound into a ring or other shape (usually made of the copper tube). As a result, a strong magnetic beam with an instantaneous polarity change is generated in the coil. When a heated substance such as metal is placed in the coil, the magnetic beam will penetrate the entire heated substance, and a large vortex is generated inside the heated substance in the direction opposite to the heating current. The current, due to the Joule heat generated by the resistance in the heated substance, causes the temperature of the substance to rise rapidly. This is the principle of induction heating.

  Induction heating equipment is to use the principle of electromagnetic induction to make the workpiece generate an induction current in the alternating magnetic field, and use the thermal effect of the induction current passing through the workpiece. A high-power electric heating device that heats the surface, inner hole, part or whole of the workpiece.
