The popularization of vacuum furnace came into being under the background of this era. Vacuum furnace is carried out in the vacuum state during the heat treatment of parts, which completely avoids the problem of oxidation. The performance of parts after vacuum heat treatment is more stable and reliable, which provides a guarantee for precision workpiece processing. According to statistics, the service life of parts processed by vacuum furnace is 30% higher than that of parts processed by ordinary process, even several times higher under the condition of similar hardness.
When we use vacuum furnaces, we will also face some problems that heat treatment process can not be completed in vacuum furnaces. There are roughly two reasons. One is that vacuum furnaces manufactured by vacuum furnaces manufacturers according to the standards of vacuum furnaces, although the technical parameters are qualified, heat treatment process is not considered comprehensively and systematically in the process of producing vacuum furnaces, which leads to the following problems. The parameters of vacuum furnace do not match those of heat treatment. Secondly, there are some defects in the vacuum heat treatment process, which can not achieve the desired results.
