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. Generally, the water-soluble quenching cooling medium decreases with temperature rise, and the hardening oil is enhanced when the temperature increases, and the cooling capacity is not changed. The polymer quenching cooling medium such as a PAC quenched cooling medium, the additive and water w...

Pay attention to the power consumption of important parts such as quenching transformers. An example is the same workpiece and inductor experiment at the same power supply, and a transformer takes 120KW, reaching temperature, while another is only 90KW.
