It is a high-temperature sintering furnace for periodic operation. The heating environment is closed and opened by controlling the lifting of the firing platform. The lifting control adopts a shear screw lifting system. It can be used for intermittent production and sintering processes of ceramic products such as zirconium oxide, aluminum oxide, and dielectric ceramics. It plays an important role in the production of high-conductivity manganese-zinc ferrite cores. The bell-shaped furnace can produce high-quality products, and the additional investment can be quickly recovered due to high-quality products. The control of temperature and atmosphere, kiln design, and airflow control in the kiln are combined to ensure the uniformity of temperature when the product is heated and cooled. The control of the kiln atmosphere during cooling is directly related to the kiln temperature.
由于钟罩炉生产的产品市场需求的增加导致工厂生产量逐渐变大， 同一工厂往往需要同时使用多个钟罩炉进行生产，由于钟罩炉加工过程中需要随时调节各种参数和过滤监测操作，因此一台钟罩炉往往需要至少一名操作人员进行操作，且对操作人员的要求也很高，因此生产的效率和质量难以统一保证。Due to the increase in market demand for products produced by bell-shaped furnaces, the factory production volume has gradually increased.

Since various parameters and filtering monitoring operations need to be adjusted at any time during the bell-shaped furnace processing, a bell-shaped furnace often requires at least one operator to operate, and the requirements for operators are also very high. Therefore, it is difficult to uniformly guarantee the efficiency and quality of production.
