Main USES: Vacuum heat treatment can realize almost all the heat treatment processes, such as quenching, annealing, tempering, carburizing, nitrification, and so on.
Vacuum heat treatment, which is a comprehensive technology combining vacuum technology and heat treatment, refers to all and part of the heat treatment process in the vacuum state. Vacuum heat treatment can realize almost all heat treatment processes, such as quenching, annealing, tempering, carburizing, nitrification, etc., as well as vacuum brazing, sintering and surface treatment, etc. The vacuum heat treatment furnace has high thermal efficiency, can achieve rapid temperature rise and temperature drop, can achieve no oxidation, no decarburization, no carburization, can remove phosphorus dust on the surface of workpiece, and has functions of degreasing and degassing, so as to achieve the effect of surface brightness and purification. Generally speaking, the workpiece processed is heated slowly in the furnace, the internal thermal temperature difference is small, and the thermal stress is small, so the deformation is small. High qualified rate of products. Can reduce the cost, has the degassing effect, thus enhances the working mechanical performance and the service life. Good working environment, safe operation, no pollution and pollution. The treated workpiece has no risk of hydrogen embrittlement. It can prevent the surface of titanium and refractory metal shell from hydrogen embrittlement. The vacuum heat treatment process has good stability and repeatability. This series of advantages, the development of vacuum heat treatment equipment and process has been paid more attention and applied more and more widely.
