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:

There is a dual wild quenching process in the tool heat treatment process. If the crackd high carbon steel tool adopts water quenching, the purpose is to use water in the austenite instability, and the oil is slow in the martensite transition area. Cold, solve the problem of workpiece quenching. ...

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.
