Vacuum furnace plays an irreplaceable role in mold production. It is
mainly used for ceramic firing, vacuum smelting, degassing of electric
vacuum parts, annealing, brazing of metal parts, and ceramic metal

The vacuum heat treatment of vacuum furnace can realize almost all heat
treatment processes, such as quenching, annealing, tempering,
carburizing and nitriding. In the quenching process, gas quenching, oil
quenching, nitrate quenching and water quenching can be realized, and
vacuum brazing, sintering and surface treatment can also be carried out.
The vacuum furnace has high thermal efficiency, can achieve rapid
temperature rise and drop, can achieve no oxidation, no decarburization,
no carburization, can remove the phosphorus chip on the surface of the
workpiece, and has the function of degreasing and degassing, so as to
achieve the effect of surface bright purification. Generally speaking,
the workpiece is heated slowly in the furnace, the temperature
difference is small, the thermal stress is small, so the deformation is
small. The qualified rate of products is high. The utility model can
reduce the cost and has the function of degassing, thereby improving the
mechanical performance and service life of the work. Good working
environment, safe operation, no pollution and public hazards. There is
no danger of hydrogen embrittlement on the surface of titanium and
refractory metal shell. The stability and repeatability of vacuum heat
treatment process are good. This series of advantages, the development
of vacuum heat treatment equipment and process is more and more
attention and application is more and more widely.

Vacuum heat treatment is a comprehensive technology combining vacuum
technology and heat treatment, which means that all or part of the heat
treatment process is carried out in vacuum. In China, vacuum is divided
into low, medium, high and ultra-high vacuum.
