What is high frequency quenching?
High-frequency quenching is mostly used for surface quenching of industrial metal parts. It is a metal heat treatment method that produces a certain induced current on the surface of the workpiece, rapidly heats the surface of the part, and then rapidly quenches. Induction heating equipment, that is, equipment that inductively heats a workpiece for surface hardening. The principle of induction heating: the workpiece is placed in the inductor. The inductor is usually a hollow copper tube with input 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 induced current is uneven in the distribution of the workpiece, strong on the surface, and weak inside, to the core close to 0, using this skin effect , the surface of the workpiece can be heated rapidly, the surface temperature rises to 800-1000 C in a few seconds, and the temperature of the core rises very little.
The workpiece is placed in an inductor wound with a hollow copper tube, and after passing through an intermediate frequency or high frequency alternating current, an induced current of the same frequency is formed on the surface of the workpiece, and the surface or part of the part is rapidly heated (the temperature is raised in a few seconds). 800 ~ 1000 C, the heart is still close to room temperature) After a few seconds, immediately spray (dip) water cooling (or spray oil cooling) to complete the immersion work, so that the workpiece surface or local to meet the corresponding hardness requirements.
