What is vacuum heat treatment?
Vacuum heat treatment is a new type of heat treatment technology that combines vacuum technology with conventional heat treatment. The vacuum environment refers to pressures below one standard atmosphere, including low vacuum, medium vacuum, high vacuum, and ultra-high vacuum. Vacuum heat treatment using tungsten wire mesh heating elements belongs to the category of controlled-atmosphere heat treatment.
Vacuum heat treatment can perform all or part of the heat treatment process under vacuum conditions. Almost all conventional heat treatment processes can be implemented under vacuum, but with significantly improved quality. Compared with conventional ceramic high-temperature sintering furnaces, vacuum heat treatment can achieve oxidation-free, decarburization-free, and carburization-free conditions, reduce surface defects such as phosphorus scales, and perform degreasing and gas removal, resulting in a bright, purified surface.
