Principle of quenching machine

Youzao energy-saving high-frequency quenching machine adopts induction heating. The principle of induction heating is: the workpiece is placed in the inductor, and the inductor is generally a hollow copper tube inputting intermediate frequency or high frequency alternating current (1000-300000Hz or higher). The alternating magnetic field generates an induced current of the same frequency in the workpiece. The distribution of this induced current in the workpiece is uneven, it is strong on the surface, but very weak in the interior, and it is close to 0 in the center. This skin effect is used. , the surface of the workpiece can be heated rapidly, and the surface temperature rises to 800-1000ºC in a few seconds, while the temperature of the core rises very little.
