What is cryogenic treatment？
Since the 1920s and 1930s, with the rapid development of material science, the principle and technology of heat treatment are becoming more and more mature. It is difficult to improve the strength and toughness of metal by conventional heat treatment process, but in many cases, the strength and initial properties of existing materials, especially the… Read more What is cryogenic treatment？
cryogenic treatment for ferrous metals
The improvement of cryogenic treatment for ferrous metals is mainly in the following aspects: Improve the hardness and strength of the workpiece Improve the wear resistance of workpiece The mechanism of metal material cold treatment equipment is as follows: Improve the hardness and strength of the workpiece In a sense, cryogenic treatment is the continuation… Read more cryogenic treatment for ferrous metals
Cold treatment of retained austenite with industrial freezer
With the continuous development of the mechanical industry, the requirements for metal materials are becoming higher and higher. How to improve the mechanical properties and service life of metal workpieces under the premise of material and heat treatment process is becoming a problem that many people at the forefront of heat treatment industry think about… Read more Cold treatment of retained austenite with industrial freezer
Prevention of Bearing Deformation in Freezing Assembly of Industrial Freezer
At present, the rolling bearing is refrigerated for 30 min (- 196 ℃) in the industrial freezer before assembly on the motorcycle, and then loaded into the motorcycle. This technology has been widely used in motorcycle industry. Before, motorcycles used imported bearings. In order to realize the localization of imported bearings, our factory produced alternative… Read more Prevention of Bearing Deformation in Freezing Assembly of Industrial Freezer
