Introduction to the working principle of high frequency induction heating equipment

High-frequency induction heating equipment uses the attachment effect of high-frequency current, which can make the eddy current magnetic field generated by metal objects increase with the increase of frequency, and form a circulating current on the surface of the metal, so that we can change the operating current. Size to control the heating depth of metal objects. This will greatly reduce the waste of energy. If the workpiece is used for heat treatment such as hot forging annealing, we need to reduce the operating frequency of the equipment. If only the surface of the workpiece is heat treated, the heating depth will be small, so the equipment should be used Increase the working frequency.
