[0002] In modern industry, nickel is widely used in aerospace, electronics, chemical industry and many other fields as an important metal material. These high-end applications have very high requirements on the performance of nickel materials, and heat treatment is the key link to improve the performance of nickel materials. Nickel processing bell jar furnace plays an important role in the heat treatment process of nickel. With the expansion of industrial production scale and the continuous improvement of the quality requirements of nickel materials, higher requirements are put forward for the performance of nickel processing bell jar furnace, and the traditional nickel processing bell jar furnace rotating door often has deficiencies in design. The opening and closing mode of some rotating doors is relatively complex, which may require multiple people to cooperate or use special tools. For example, through a large number of bolt fixation or complex mechanical lock structure, the operator needs to spend a lot of time to open and close the rotating door when loading and unloading nickel materials, which seriously affects the work efficiency, especially in large-scale production, frequent loading and unloading operation makes this low efficiency problem more prominent, and leads to poor air tightness. Because of poor sealing, external air is easy to enter the furnace, which may cause oxidation and other adverse reactions of nickel materials at high temperature, reducing the quality of nickel materials. The traditional cooling method is natural cooling, which is very slow. The grain growth and stress release in the nickel material are difficult to control, which may lead to uneven material performance and cannot meet the requirements of high-quality nickel materials. Therefore, we propose a nickel processing bell jar furnace based on electric heating technology to solve this problem. CONTENT OF THE UTILITY MODEL
