Heat treatment process: surface hardening, local hardening

Induction hardening (medium, high, super audio) is mostly used for surface hardening of industrial metal parts. It is a metal heat treatment method that generates a certain induction current on the surface of the workpiece, rapidly heats the surface of the part, and then quenches it quickly. Induction heating equipment refers to equipment that performs induction heating on the workpiece for surface hardening. The principle of induction heating: the workpiece is placed in an inductor, which is generally a hollow copper tube with 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 on the workpiece is uneven. It is strong on the surface but weak on the inside. It is close to 0 to the core. Use this skin effect , The surface of the workpiece can be heated quickly, and the surface temperature will rise to 800-1000℃ within a few seconds, while the temperature of the core part will rise very little. To

prednost:

High hardness: The heating speed is extremely fast, so the transformation temperature is increased, so as to achieve the purpose of grain refinement, and the structure is strengthened due to the small grain size.

Small deformation: due to local hardening, the overall deformation of the workpiece becomes smaller.

Surface stress resistance: fatigue resistance.
