Vacuum heat treatment processing technology

Vacuum heat treatment processing technology mainly refers to the combination of vacuum technology and heat treatment technology of the new heat treatment technology, among them, vacuum heat treatment in vacuum environment refers to the below an atmospheric pressure of the atmosphere environment, including the low vacuum, the medium vacuum, high vacuum and high vacuum, etc., so, vacuum heat treatment also belong to the controlled atmosphere heat treatment.

Vacuum heat treatment refers to all and part of the heat treatment process in the vacuum state, vacuum heat treatment can achieve almost all the conventional heat treatment can be involved in the heat treatment process, but the quality of heat treatment is greatly improved.

Compared with the conventional heat treatment, the vacuum heat treatment processing technology can simultaneously achieve no oxidation, no decarburization, no carburizing, can remove the phosphorus chip on the surface of the workpiece, and has the effect of degreasing and degassing, so as to achieve the effect of surface brightness and purification.

Actually, vacuum heat treatment processing technology abroad application earlier, the United States and Japan in 1968, has developed the vacuum quenching oil and water-based quenching medium, thereby, vacuum quenching technology in heat treatment industry gets rapid development, from a single chamber furnace to combined fleet, from the general development to the high pressure gas quenching vacuum hardening, vacuum water quenching, vacuum carburizing and carbonitriding and multivariate altogether permeability, etc.
