A kind of dissolving device of rare earth magnesium alloy

Abstract

The invention discloses a dissolution device of a rare earth magnesium alloy. The dissolution device of the rare earth magnesium alloy comprises a furnace body, a crucible embedded into the furnace body, a rotating shaft, a material cage and a hopper, wherein a cover plate is arranged in the position of a top opening of the crucible, a feeding port where magnesium alloy is placed to the crucible is formed in the cover plate, the rotation shaft is arranged on the cover plate in a pivoted mode, the rotating shaft extends into the crucible, the lower end portion of the rotating shaft is provided with at least one impeller, a driving mechanism used for driving the rotating shaft to rotate is further installed on the cover plate, the material cage is used for containing rare earth, the material cage is connected to the rotating shaft synchronously and is located above the impeller, a plurality of through holes are formed in the side face of the material cage, the hopper is installed on the cover plate, and a discharging port of the hopper penetrates through the cover plate and is located above an upper opening of the material cage. Compared with the prior art, the dissolution device of the rare earth magnesium alloy has the advantages that the material cage rotating in the circumference direction is utilized, the dissolution rate of the rare earth inside the material cage is improved, feeding can be achieved without the need of taking out the material cage in the process of production, and therefore the continuity and the high efficiency of the casting process are guaranteed.

Description

technical field [0001] The invention relates to the technical field of magnesium alloy processing, in particular to a rare earth magnesium alloy dissolution device. Background technique [0002] Magnesium alloys containing rare earth elements are called rare earth magnesium alloys, which have the characteristics of high strength, strong heat resistance and corrosion resistance. [0003] At present, in the production process of rare earth magnesium alloy, high-temperature magnesium liquid is used to dissolve rare earth and then cast rods and ingots to form. Specifically, fixed cages are used to fill rare earths, and then the cages are immersed in high-temperature magnesium liquid. In the crucible, at high temperature, the rare earth in the cage is dissolved by the magnesium liquid. When working, the stirring blade is mechanically stirred on one side of the cage. This traditional rare earth magnesium alloy production device uses a fixed material cage, which makes it difficult...

AI Technical Summary

Problems solved by technology

This traditional rare earth magnesium alloy production device uses a fixed material cage, which makes it difficult for the rare earth to completely dissolve in the magnesium solution in a limited space only by heating. Therefore, the rare earth dissolution period in the material cage is longer. , affecting the continuity and efficiency of the entire casting process

In addition, when feeding the existing fixed cage, after the casting of the rare earth magnesium alloy in the crucible is completed, the fixed cage needs to be taken out and refilled with rare earth, which leads to the lack of guarantee of the sealing of the whole device, resulting in the loss of magnesium liquid during the production process. Contaminated or oxidized in the crucible, these pollutants or oxides are included in the product, which reduces the qualified rate of the product, and poor sealing usually leads to serious burning of the rare earth in the crucible
