Description

Technical Field

[0002] Box furnace is a kind of equipment used for heat treatment processes such as heating, baking, sintering, annealing, etc. It is usually composed of furnace body, heating element, control system, etc. The appearance of box furnace is rectangular or cube-shaped, with a large internal space, which is suitable for heat treatment of large or multiple workpieces. Box furnace is widely used in metal processing, ceramic manufacturing, glass processing, electronic component manufacturing and other industries.

[0003] However, there are some technical challenges when grinding parts in traditional box furnaces. First, traditional box furnaces can usually only control the temperature during the grinding process by setting the heating temperature, but cannot accurately control the temperature distribution in the grinding area, which may cause the surface temperature of the ground parts to be too high or too low, affecting the grinding effect. Secondly, it is difficult for traditional box furnaces to control the atmosphere during the grinding process, causing the ground parts to come into contact with oxygen, which can easily cause oxidation and other problems, affecting the grinding effect and part quality. In addition, traditional box furnaces cannot achieve a vacuum or protective gas environment during the grinding process, causing the ground parts to be affected by oxidation, pollution, etc., and the grinding effect is unstable. Therefore, traditional box furnaces have technical bottlenecks in temperature control, atmosphere control, and stability of grinding effects. Utility Model Content
