Technical Field

[0001] The utility model relates to the technical field of roasting furnaces, in particular to a roasting furnace for crucible production, which is convenient for the crucible to enter. Background Art

[0002] The raw materials for the production of crucibles can be summarized into three types. The first is crystalline natural graphite, the second is plastic refractory clay, and the third is calcined hard kaolin skeleton clinker. Since 2008, high-temperature resistant synthetic materials have been used. This clinker has a significant effect on improving the quality of crucible products, enhancing the density and mechanical strength of crucibles. Among graphite crucibles, there are three types: general graphite crucibles, special-shaped graphite crucibles, and high-purity graphite crucibles. Various types of graphite crucibles have different raw materials, production methods, process technologies, and product models and specifications due to different performances, uses, and conditions of use. Roasting is a process of completing a certain chemical reaction at a temperature lower than the melting temperature of the material. It is a component of the preparation of the charge. Most of the materials always exist in a solid state. Therefore, the roasting temperature is limited to ensure that the material does not melt significantly.

[0003] In the current crucible production process, when the crucible is placed in or taken out of the roasting furnace, workers usually use pliers or other tools to reach into the roasting furnace to take out the crucible. The manual labor intensity is high, the efficiency of roasting objects entering and exiting the furnace is low, and the crucible cannot be conveniently placed in or taken out of the roasting furnace, which is not conducive to the efficient production of the enterprise.
