Automatic High Efficiency Chest Freezer Deep Freezer Multipurpose Furnace
Product Description
The red hardness test results of W 18Cr4V steel also show that the cryogenic treatment process specification also has an effect on the red hardness of high-speed steel. High-speed steel undergoes cryogenic treatment, in addition to the transformation of a large amount of retained austenite into martensite, at the same time, because the quenched martensite is in a more thermodynamically unstable state at ultra-low temperature, the decomposition driving force is greater, and at this ultra-low temperature , The diffusion and migration ability of carbon atoms is weak, and a large number of dispersed ultra-fine carbides are precipitated on the martensite matrix, which improves the tempering resistance and performance of high-speed steel to varying degrees; after conventional heat treatment, the amount of retained austenite Significantly reduced, and thermal stabilization occurs, and the supersaturation of martensite is also reduced. Although cryogenic treatment can improve the red hardness and performance of high-speed steel, the cryogenic process must be mastered in the liquid nitrogen cryogenic box for tool cryogenic treatment. And strictly control the process; also know the composition of the tool material and the process of heat treatment. There is also called cryogenic treatment (or cryogenic treatment)
The application prospect of the metal cryogenic tempering integrated furnace in the manufacturing industry: In the mold manufacturing process, the quality of the mold directly affects the business status of the enterprise. Using cryogenic treatment technology to improve the service life of the mold and increase the economic benefit of the enterprise . Therefore, low-temperature modification technology has been applied in the mold industry and has achieved good economic benefits, and it has great practical value when it is extended. Cryogenic treatment has a promising application in the fields of aerospace, weapons, construction machinery, roads and bridges, semiconductors, electrical appliances, computers, etc. The cold treatment of molds has an incomparable life!
After cryogenic treatment, material stability is improved, harmful stress is reduced, and tool life is increased
