Abstract

The invention discloses a magnesium alloy refining crucible with improved purity and its application in the field of metal processing, in order to overcome the disadvantages in the prior art that the magnesium alloy is only in the preliminary processing state and the metal performance of the magnesium alloy is not up to standard, in order to overcome this defect The technical solution includes a refining crucible body with an elliptical cross-section, and the refining crucible body is provided with a feed inlet, a stirring and diverting device, and a cryogenic treatment chamber in sequence along the material supply direction, and the stirring and diverting device includes a circular cross-section The inner ring rotor and the circular gear driving the inner ring rotor, the inner ring rotor meshes with the circular gear, and the bottom end of the inner ring rotor has an arc-shaped notch, and an arc-shaped rotating plate is fixedly connected to the inside of the notch. Compared with the traditional refining crucible, the technical solution utilizes the circumferentially rotating inner ring rotor to perform hot rolling treatment on the magnesium alloy, which reduces the molecular gap inside the magnesium alloy and improves the metal properties of the magnesium alloy.

Description

technical field [0001] The invention belongs to the field of metal processing, in particular to a magnesium alloy refining crucible with improved purity. Background technique [0002] At present, magnesium refining at home and abroad mostly uses the solvent method to remove impurities in the crude magnesium. Magnesium chloride is electrolyzed to obtain crude magnesium, and the impurities in the crude magnesium are also removed through the solvent method to achieve the quality of refined magnesium, especially in sponge titanium manufacturers. The purity requirements for refined magnesium are particularly high, which directly affects the quality of sponge titanium products. Since the purchased magnesium ingots and electrolyzed crude magnesium have more impurities, the magnesium ingots or electrolytic magnesium enter the magnesium refining crucible to be melted and refined, and the metal impurities and non-metal impurities are replaced and adsorbed by the solvent. The density ...
