The main purpose of the induction quenching worker temper is to reduce quenching stress to avoid quenching cracks; sometimes, the tempering is to reduce the hardness of the workpiece technical requirements.
The workpiece induces the temper after quenching, and there are generally three ways:
1. When the fireworks are quenched, the cooling does not perform in advance, so that the residual heat of the center of the center of the hardened layer is transferred to the hardening layer, thereby rearing the hardening layer again, reaches a certain tempering temperature, so that The hardening layer obtains the required tissue and performance.
2. Induction tempering uses the original quenching heating power supply, under the original sensor equipment, and reducing the power method for induction tempering.
