Special equipment for liquid nitrogen cryogenic treatment of rolls
After the rolls undergo liquid nitrogen cryogenic treatment, On the one hand, it can reduce the amount of normal austenite, control the amount of retained austenite in the roll below ~%, and maintain the good performance of the roll in use. On the other hand, cryogenic treatment can increase the martensite content of the roll, thereby improving the quality of the roll. The hardness increases the wear resistance of the roll and provides the roll with the ability to withstand accidents. In addition, after cryogenic treatment of the roll, fine carbides can be precipitated, the structure can be refined, the structure and size can be stabilized, the performance of the material can be fully utilized, and the service life of the roll can be increased.
