Description

Technical Field

[0001] The utility model belongs to the technical field of mineralization furnaces, and particularly relates to a beryllium smelting mineralization furnace. Background Art

[0002] A beryllium smelting mineralization furnace is a device used for refining and purifying beryllium elements. During the smelting process, beryllium-containing ores are first crushed and ground, and then placed into the smelting mineralization furnace for heating and reaction. Beryllium has important application values in fields such as aerospace, electronics, and medical devices. Therefore, the beryllium smelting mineralization furnace is of great significance in industrial production.

[0003] During the smelting process of beryllium, the main raw material is beryl, with a certain proportion of calcite as a flux (the main components include BeO, FeO, SiO2, and limestone, etc.). The raw materials are melted at high temperature in an electric arc furnace to break the crystal form of beryl, forming fine beryllium glass that is easy to react with concentrated sulfuric acid.

[0004] However, the existing beryllium smelting mineralization furnace also has certain deficiencies. The existing mineralization furnace completely relies on the functions of refractory bricks and heat-insulating and heat-preserving bricks to achieve heat insulation effects. It is difficult to perform regional cooling gradient treatment on the molten pool of the furnace body. Moreover, the silicate degree of the melt is acidic, which has extremely strong corrosiveness to refractory materials. The internal refractory materials are often corroded by the melt, resulting in serious perforation phenomena, and further causing the problem of forced shutdown for maintenance. Summary of the Invention
