Safety features of vacuum furnace

The heat treatment of vacuum furnace is a comprehensive technology combining vacuum technology and heat treatment, which means that all and part of the heat treatment process is carried out in vacuum. In China, vacuum is divided into low, medium, high and ultra-high vacuum. At present, the working vacuum of most vacuum heat treatment furnaces is in the range of 1.33 ~ 1.33 10? PA.

Vacuum heat treatment can realize almost all heat treatment processes, such as quenching, annealing, tempering, carburizing and nitriding. In the quenching process, it can realize gas quenching, oil quenching, nitrate quenching, water quenching, etc., and it can also carry out vacuum brazing, sintering, 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 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.
