Special liquid nitrogen cryogenic chamber for gear cryogenic treatment
Dejieli Gear Special Cryogenic Treatment Equipment (Cryogenic Furnace, Stress Relief Furnace) is a liquid nitrogen refrigeration equipment used to improve the performance of gears and other workpieces, increase the wear resistance and dimensional stability of the workpieces, and make the service life of Times increased. Various models and specifications can also be customized, welcome to buy!
The gear special liquid nitrogen cryogenic box is mainly used to eliminate residual austenite and completely convert it into martensite. Improve the wear resistance of the workpiece, the long-term impact fatigue strength, and reduce the ductility and internal deformation of the material. The liquid nitrogen cryogenic treatment box developed by Dejieli adopts well-known brand components with stable performance and reliable operation. Stainless steel inner tank, double-layer insulation, beautiful appearance, low noise, low energy consumption, economical and practical. It has gradually won market recognition with its strong cost-effective advantages. It is widely used in the low-temperature cryogenic treatment of metal materials such as gears, parts, tools, drills, hardware, molds, and bearings. Continue the cooling process of the quenched metal material to reach a certain temperature lower than room temperature, thereby improving the performance of the metal material.
Dejieli liquid nitrogen cryogenic box equipment application:
The wear resistance and service life of carbide tools, cutting tools, and drill bits are improved;
High-speed tool steel knives, cutting tools, measuring tools, drill bit wear resistance and service life improvement;
The performance and thermal stability of diamond drill bits, saw blades and top hammers are improved;
