present quenching equipment used to cool byproduct oven coke. Among the major problems associated with wet quenching processes, which spray or flood the red hot coke with water, are: (1) air pollution during the pushing and wetquenching operations; (2) water pollution potential; (3) substantial energy waste during wet quenching; and (4) coke quality degeneration and loss of usable coke

But our factory used the induction hardening equipment for internal spline gear induction quenching process, in order to solve its cone shrinkage defects, and it achieved good results. Drumshaped or tapered shrinkage of the internal spline gear is heated by induction hardening machine to 820 ℃ for induction quenching, and then to carry out water cooling on the gear hole wall with cooling

Cryogenic treatments are usually done immediately following quenching and before any tempering is done. It does increase the hardness and wear resistance and reduces metal fatigue, but it may also increase the chances of cracking during the process. This is because cryogenic treatments are really just an extension of the quenching process.
WhatsApp These involve water, different concentrations of salt water, and soda. These are the fastest ways to cool metals during the quenching process. Aside from possibly warping the metal, safety precautions also must be taken when using caustic sodas, as they can be harmful to the skin or eyes.

Quenching is normally applied at 180–200 °C, but temperatures up to 500 °C are also used. The cooling capacity is affected by added water, using special equipment (about –% water), and temperature as well as the degree of agitation. Modern technology consists of closed systems in which salt is reused and no wastewater is released.

Oil quenching a less dramatic technique than water quenching, can be used because hardness can occur at a slower cooling rate. Internal stress is reduced, and there is less chance of warpage, cracking, Surface hardening process that heats selected areas of steel with a direct flame before quenching.
