What are the characteristics of vacuum heat treatment furnace?
Vacuum heat treatment is a comprehensive technology combining vacuum and heat treatment. It refers to that part of the heat treatment process is carried out in vacuum. The vacuum heat treatment furnace has high thermal efficiency, can achieve rapid rise, compliance and temperature reduction, can achieve no oxidation, no decarburization, no carburization, can remove the phosphorus chips on the surface of the workpiece, and has the functions of degreasing and degassing, so as to achieve the effect of bright and clean surface.
Vacuum heat treatment process means that all and part of the heat treatment process is carried out under vacuum. In China, vacuum is divided into low, medium, high and ultra-high vacuum. At present, the working vacuum of numerous vacuum heat treatment furnaces is 1.33~1.33 × 103Pa。 Vacuum heat treatment can almost complete 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 completed. Vacuum brazing, sintering and surface treatment can also be carried out.
Zhengzhou Nuotai technology has developed vacuum heat treatment furnace, vacuum sintering furnace and vacuum annealing furnace specifically for the market demand of vacuum heat treatment. After years of continuous upgrading, the process of notata technology in the vacuum heat treatment furnace is becoming more and more mature. At present, it has been successfully applied by many domestic enterprises.
