Product overview of special liquid nitrogen cryogenic tank for quenching component cooling:
The purpose of quenching is to make the undercooled austenite undergo martensite or bainite transformation to obtain martensite or bainite structure, and then cooperate with tempering at different temperatures to greatly improve the rigidity, hardness, wear resistance, fatigue strength and toughness of steel
After completing the heat treatment process, the hardness and mechanical properties of many parts are greatly improved, but there are still many problems, such as residual austenite, coarse structure and grain, The solid solution supersaturation and residual internal stress of material carbides will affect the hardness, wear resistance and dimensional stability of parts
Through the unremitting research of many researchers at home and abroad, cryogenic and ultra cryogenic treatment processes are considered to be the Zui optimal methods to solve these problems
Jinan HuiFu liquid nitrogen cryogenic tank is mainly used to quench parts, eliminate residual austenite, completely convert into martensite, improve wear resistance, long-time impact fatigue strength, and reduce material ductility and internal deformation

Product structure of special liquid nitrogen cryogenic tank for quenching component cooling:
HuiFu cryogenic box adopts man-machine interface + PLC + module programmable control mode to monitor the temperature change in the box in real time, with manual and automatic dual operation functions
The equipment takes liquid nitrogen as the cooling medium, the stainless steel chassis is beautiful and durable, and the high-quality high-density polyurethane foam insulation layer is used for heat insulation
The system has reasonable structure, standardized manufacturing process, compact component layout, simple operation, powerful function and humanized communication interface; The low temperature can reach - 196 ℃, and the cooling speed is fast
The special liquid nitrogen cryogenic tank for cooling HuiFu quenching parts adopts liquid nitrogen dispersion refrigeration technology and temperature control technology to make the constant temperature and cooling processes of products uniform and stable

Advantages of special liquid nitrogen cryogenic box for cooling quenched parts: ,
