Key words:
Due to the obvious advantages of vacuum heat treatment in terms of processing quality, energy saving, especially environmental protection, it has rapidly developed into the mainstream of contemporary heat treatment technology and equipment renewal; vacuum heat treatment has accounted for 25% of the total metal heat treatment market.
Vacuum heat treatment refers to all and part of the heat treatment process in a vacuum state, vacuum heat treatment can achieve almost all of the conventional heat treatment can be involved in the heat treatment process, but the quality of heat treatment is greatly improved.
Key words:
Vacuum heat treatment is a new type of heat treatment technology combining vacuum technology and heat treatment technology, vacuum heat treatment in the vacuum environment refers to the atmosphere environment below an atmospheric pressure, including low vacuum, medium vacuum, high vacuum and ultra-high vacuum, vacuum heat treatment actually belongs to the atmosphere control heat treatment.
Vacuum heat treatment refers to all and part of the heat treatment process in a vacuum state, vacuum heat treatment can achieve almost all of the conventional heat treatment can be involved in the heat treatment process, but the quality of heat treatment is greatly improved. Compared with conventional heat treatment, vacuum heat treatment at the same time, can achieve no oxidation, no decarburization, no carburizing, can remove the workpiece surface phosphorus, and degreasing degassing and other effects, so as to achieve the effect of surface bright purification.
