A vacuum casting platform for pumping liquid rare earth metal

Abstract

The invention provides a vacuum casting platform for pumping liquid rare earth metals, which includes a vacuum injection cover, a suction pipe, a lifting frame for the vacuum injection cover, an ingot mold table lifting and turning mechanism, and an ingot mold table. The existing technology has the disadvantages of rare earth metal oxidation and large amount of slag in the process of taking out and casting. In the present invention, the process of taking out the molten metal from the electrolytic cell and casting the ingot is carried out under vacuum conditions, which can avoid the ingot casting process. Oxidation, slagging. The structure and assembly method of the liquid suction pipe of the present invention avoids the accumulation of metal or slag in the pipe to block the pipeline, can overcome the shortcomings of conventional vacuum table bag extraction equipment and manual spoon digging equipment, and has the advantages of simple equipment, easy operation, and low labor intensity The advantages.

Description

technical field [0001] The invention belongs to the field of metal smelting, in particular to a vacuum casting platform for pumping liquid rare earth metals. Background technique [0002] At present, when rare earth metals are smelted by electrolysis, the molten metal is taken out from the electrolytic cell, and the ingots are usually dug out by manual spoons or vacuum table bags, and then cast into ingots or ingots. Disadvantages such as large amount of slag and high labor intensity; the existing vacuum table bag equipment is prone to high failure rate due to slagging and other reasons, damage or large consumption of table bag lining materials, troublesome operation, high consumption of lining materials, and heavy maintenance workload Shortcomings, not only that, the existing technical liquid rare earth metal casting process has the shortcoming of metal oxidation due to pouring and casting under air conditions. If a kind of metal liquid can be directly taken out from the el...

[0002] At present, when rare earth metals are smelted by electrolysis, the molten metal is taken out from the electrolytic cell, and the ingots are usually dug out by manual spoons or vacuum table bags, and then cast into ingots or ingots. Disadvantages such as large amount of slag and high labor intensity; the existing vacuum table bag equipment is prone to high failure rate due to slagging and other reasons, damage or large consumption of table bag lining materials, troublesome operation, high consumption of lining materials, and heavy maintenance workload Shortcomings, not only that, the existing technical liquid rare earth metal casting process has the shortcoming of metal oxidation due to pouring and casting under air conditions. If a kind of metal liquid can be directly taken out from the electrolytic cell and directly cast into The ingot equipment can not only overcome the shortcomings of metal oxidation in the prior art, but also overcome the defects of the existing vacuum table bag extraction equipment and manual scoop extraction equipment, such as high labor intensity and cumbersome operation.
