It is widely used in various industries

Welcome users from all industries to HuiFu to discuss cooperation
Product introduction of special liquid nitrogen cryogenic treatment equipment for bit:
The special liquid nitrogen cryogenic treatment equipment for bit is mainly used to eliminate the residual austenite and completely convert it into martensite
Improve the wear resistance, long-time impact fatigue strength, and reduce the ductility and internal deformation of the material
The liquid nitrogen cryogenic treatment tank developed by HuiFu adopts internationally famous brand parts, with stable performance and reliable operation
Stainless steel liner, double-layer insulation, beautiful appearance, low noise, low energy consumption, economical and practical
With strong cost performance advantages, it has gradually won the recognition of domestic and international markets
It is widely used in low temperature cryogenic treatment of metal materials such as parts, cutting tools, drill bits, hardware, molds and bearings
The cooling process of the quenched metal material is continued to reach a certain temperature lower than the room temperature, so as to improve the performance of the metal material
After treatment, the wear resistance and dimensional stability of metal workpiece are increased, and its service life is doubled

Application of special liquid nitrogen cryogenic treatment equipment for bit:
Improvement of wear resistance and service life of cemented carbide tools, cutting tools and drill bits;
Improve the wear resistance and service life of high-speed tool steel cutting tools, cutting tools, measuring tools and drill bits;
The transmission performance and thermal stability of diamond bit, saw blade and ejector hammer are improved;
Improvement of dimensional stability of precision mechanical parts;
The impact resistance and service life of hot and cold working dies in mechanical manufacturing industry are improved;
The wear resistance and service life of oil nozzle, spring, gear and bearing are improved
