Vacuum Heat Treatment in Tool Forging

Release time：2023-06-08

Vacuum heat treatment is a new type of heat treatment technology that combines vacuum technology and heat treatment technology. The vacuum environment in which vacuum heat treatment is located refers to the atmosphere environment below one atmospheric pressure, including low vacuum, medium vacuum, high vacuum, and ultra-high vacuum. Vacuum heat treatment is actually also an atmosphere controlled heat treatment. Vacuum heat treatment refers to the process where all or part of the heat treatment process is carried out in a vacuum state, greatly improving the quality of the heat treatment. Compared with conventional heat treatment, vacuum heat treatment can achieve no oxidation, decarburization, or carburization, remove phosphorus shavings from the surface of the workpiece, and have functions such as degreasing and degassing, thereby achieving the effect of surface brightness purification.
