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 sealing.
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.
