All vacuum heat treatment services including solutionization, brazing and various annealing and quenching can be provided by using equipment that can carry out continuous treatment of vacuum exhaust, heating and cooling under fully automatic control.

Vacuum heat treatment is a new heat treatment technology that combines vacuum technology and heat treatment technology. The vacuum environment in which vacuum heat treatment is located refers to an atmosphere environment below one atmospheric pressure, including low vacuum, medium vacuum, high vacuum and ultra-high vacuum. The actual vacuum heat treatment It also belongs to atmosphere-controlled heat treatment. Vacuum heat treatment means that all and part of the heat treatment process is carried out in a vacuum state, and the heat treatment quality is greatly improved. Compared with conventional heat treatment, vacuum heat treatment can achieve no oxidation, no decarburization, no carburization, remove phosphorus chips on the surface of the workpiece, and have the functions of degreasing and degassing, so as to achieve the effect of bright and clean surface.
