The role of liquid nitrogen cryogenic box
The liquid nitrogen cryogenic box is mainly used for industrial cold treatment, so that uniform, fine and dispersed carbides are precipitated on the metal structure matrix. The precipitation of this carbide will significantly improve the wear resistance and friction performance of the metal, the hardness will also be improved, and will directly increase the service life of the wear parts. It is an ideal substitute for liquid nitrogen. It is widely used in mechanical assembly.
After cryogenic treatment, the internal thermal stress and mechanical stress of the material are greatly reduced. During the cooling process, plastic flow occurs in the micropores or stress concentration locations. During the heating process, the surface of these vacancies will generate compressive stress, which can greatly reduce the damage to the local performance of the workpiece by defects, and effectively reduce the possibility of deformation and cracking of the metal workpiece.
Ultra-cryogenic cold boxes can be widely used in high-speed steel, cemented carbide, measuring tools, molds, saw blades, oil pumps, nozzles, automotive bearings, golf heads, rolls, cryogenic valves, aluminum alloys, copper alloys, hardware, tools, springs, Cryogenic treatment of various metal materials such as gears, bearings, diamonds, and environmental simulation of various parts of mines, geological drilling rigs, mechanical parts, etc., as well as supercooling rings and ultra-low temperature rings.
