Constant-temperature ladle for vacuum suction and injection of liquid rare earth metal

Abstract

The invention provides a constant-temperature ladle for vacuum suction and injection of liquid rare earth metal. The constant-temperature ladle is composed of a molten metal containing ladle, a moltenmetal suction pipe, a molten metal outlet sealing opening and closing assembly, a vacuum pipeline component, two ladle body connecting pieces, a tilting component and an electric heating disc; the gas pressure in a molten metal storage inner container is adjustable, metal oxidation can be avoided in the vacuum suction process, electrolyte is prevented from entering the molten metal storage innercontainer in the pipe inserting process of the molten metal suction pipe, the function of thoroughly pouring metal, the electrolyte and the like out of the molten metal storage inner container is achieved, and the phenomenon that the metal or the electrolyte is slagging in the ladle is avoided. According to the constant-temperature ladle for vacuum suction and injection of the liquid rare earth metal, heat loss is greatly reduced by an insulating layer structure, the electric heating function enables the temperature of molten metal in the molten metal storage inner container to be constant, the requirement that the same ladle extracts liquid metal in different electrolytic tanks and gathers the liquid metal together for casting (ingot casting) is met, the quantity of metal ingots cast at atime is multiplied, components are more uniform, and the constant-temperature ladle has the advantages of reducing the power-off time of the manual ladle and spoon, reducing the labor intensity and improving the yield and quality.

Description

technical field [0001] The invention belongs to the field of metal smelting, in particular to a constant temperature table bag for vacuum suction and injection of liquid rare earth metals. Background technique [0002] At present, the equipment that uses vacuum suction equipment to take the molten metal out of the electrolytic cell, such as the aluminum outlet bag, is suitable for the production of metal aluminum, magnesium, etc. by electrolysis, but it is not suitable for electrolysis due to large equipment, complicated operations, and defects such as electrolyte slagging. Rare earth metals are produced by the traditional method, and the way to discharge rare earth metals from the electrolytic cell is generally to use manual or mechanical scoops and spoons to take out the method and equipment. When taking out the operation, sometimes the electrolytic cell needs to be powered off, which has the disadvantage of reducing production. The amount of liquid rare earth metal in the...

[0002] At present, the equipment that uses vacuum suction equipment to take the molten metal out of the electrolytic cell, such as the aluminum outlet bag, is suitable for the production of metal aluminum, magnesium, etc. by electrolysis, but it is not suitable for electrolysis due to large equipment, complicated operations, and defects such as electrolyte slagging. Rare earth metals are produced by the traditional method, and the way to discharge rare earth metals from the electrolytic cell is generally to use manual or mechanical scoops and spoons to take out the method and equipment. When taking out the operation, sometimes the electrolytic cell needs to be powered off, which has the disadvantage of reducing production. The amount of liquid rare earth metal in the liquid rare earth metal is small, and there are disadvantages of composition differences between pools and times. Sometimes, in order to provide large batches of ingots with the same composition, it is even necessary to use special equipment for re-smelting in a furnace. If it can be invented The equipment that overcomes the disadvantages of slagging in the existing platform and is suitable for the characteristics of the liquid rare earth metal electrolytic cell and has a constant temperature function for vacuum pumping liquid rare earth metal can not only increase the output of the electrolytic cell, but also reduce labor intensity and avoid recombination. Furnace smelting, increasing compositional uniformity of rare earth metals, improving quality
