Problems solved by technology

The solubility of these refractory impurities in magnesium alloy is small, the melting point is high, and the specific gravity is larger than that of magnesium. Although this method can remove the fusible impurities in the alloy, it does not rule out the secondary pollution of the melt. More important It takes a long time for the adsorption and precipitation of inclusions, and the solvent refining method cannot effectively degas, and at the same time, it leads to difficulty in gas protection, large consumption, and cumbersome process steps, which greatly reduces production efficiency.

Abstract

This invention relates to a stirring rotor with spray-drifting ability for refining Mg alloy. The stirring rotor comprises a rotor body with vent pipes, a hollow vent axis with the top side connected with vent pipes and the bottom side connected with rotor body, a big driving wheel located on the vent axis and connected with driving device, and a bearing seat located on the vent axis. The rotor body is fixed with vent axis. On the bottom of rotor body, main vents are arranged radially and uniformly and connected with vent pipes. The apparatus contains a rotor with double vent pipes, the gas in the pipes are broken into fine and dispersible bubbles through rotating the rotor, the bubbles dispersing in the Mg alloy melt can carry gas and impurities in the Mg alloy melt to the surface of the melt, and the Mg alloy is refined through the above process.

Description

technical field [0001] The invention relates to a magnesium alloy refining equipment, in particular to a stirring and blowing rotor for magnesium alloy refining. technical background [0002] In recent years, magnesium alloy has become a new type of material with potential for development and application. It has high specific strength and specific stiffness, good thermal conductivity, good damping and shock absorption and electromagnetic shielding performance; at the same time, it has excellent cutting performance and casting With a series of advantages such as good performance and easy recycling, with the breakthrough of processing technology and the sharp drop of price, magnesium alloy has been used in various fields more and more. [0003] In view of the various advantages of magnesium alloys, magnesium material production enterprises are also increasing. China is a country with large magnesium resources in the world, and its magnesium production has accounted for about ...
