Description

Technical Field

[0001] The utility model relates to the technical field of rare earth metal production, and more specifically to a high-temperature uniform stirring sintering device. Background Art

[0002] Sintering is a traditional process that converts powdered materials into dense bodies. People have long used this process to produce ceramics, powder metallurgy, refractory materials, ultra-high temperature materials, etc. Generally speaking, after the powder is formed, the dense body obtained by sintering is a polycrystalline material, and its microstructure is composed of crystals, glass and pores. The sintering process directly affects the grain size, pore size and grain boundary shape and distribution in the microstructure, which in turn affects the performance of the material. Usually, when the metal inside the rare earth is refined, the rare earth needs to be sintered.

[0003] When the existing sintering device is in use, the rare earth usually needs to be stirred. Then the existing stirring method usually uses a single stirring arm to stir the rare earth inside the sintering device. The stirring method is relatively simple and requires a long time of stirring to stir the rare earth evenly, so that the rare earth is heated evenly for sintering, which reduces the work efficiency. For this reason, we propose a high-temperature uniform stirring sintering device. Utility Model Content
