What is liquid nitrogen cryogenic box

     The liquid nitrogen cryogenic box uses liquid nitrogen as the cooling medium, which can reduce the temperature of the cryogenic cryogenic box to -196 ° C, and the temperature can be controlled. The inner wall of the equipment is stainless steel, the temperature is controlled by an intelligent controller, the system structure is scientific, and the operation is intuitive and convenient. The liquid nitrogen cryogenic box can continue the cooling process of the quenched metal material to a certain temperature far below room temperature, thereby achieving the purpose of improving the performance of the metal material. Cryogenic processing technology is a new process technology that has been developed in recent years to improve the performance of metal materials. It is currently the most effective and economical technical means. During the cryogenic treatment process, a large amount of residual austenite in the metal transforms into martensite, especially the supersaturated metastable martensite and then from -196 degrees Celsius to room temperature will reduce the saturation, precipitation and dispersion, and the micro profit will decrease. The finely dispersed carbides can hinder the movement of dislocations when the material is deformed, thereby strengthening the matrix structure. At the same time, the ultra-fine carbonization exerts the effect of strengthening the grain boundary, thereby improving the performance of the tool and die, so that the hardness, impact resistance and wear resistance are significantly improved.
