Rotary stirring rare earth alloy smelting device

Abstract

The invention discloses a rotary stirring rare earth alloy smelting device. A heating sleeve sleeves the outer side of a graphite crucible; a support frame is arranged on the lower side of the graphite crucible; a driving device for driving the support frame to rotate is arranged on the lower side of the support frame; multiple arc clamping arms are arranged on the side wall of the graphite crucible; and multiple balls are embedded in the inner arc sides of the clamping arms. The graphite crucible is supported and stabilized by the support frame; meanwhile, the support frame drives the graphite crucible to rotate; the balls are arranged on the inner arc sides of the clamping arms; the clamping arms and the side wall of the graphite crucible are in rotary fit through a rolling effect of theballs to achieve an effect of uniformly mixing molten metal in the graphite crucible; and an auxiliary stirring device is not added in the graphite crucible, so that the pollution of the molten metalby a stirring shaft is prevented, and meanwhile, the problem of difficult cleaning of the stirring shaft after use of the graphite crucible is solved.

Description

technical field [0001] The invention relates to the technical field of rare earth metal smelting, in particular to a rotary stirring type rare earth alloy smelting device. Background technique [0002] In industrial production, according to the formula requirements, various metal materials, such as rare earth metals, pure iron, boron iron, zirconium, etc., are placed in the crucible of a vacuum melting furnace, melted, electromagnetically stirred, and homogenized by an induction heating device, and finally the molten alloy steel Pour into an ingot mold to form a rare earth alloy. [0003] In the process of smelting metals, various rare earth metals are doped, and the ingredients are many and complex, and it needs to be stirred evenly to exert the best adding effect. Stirring, due to the high temperature in the crucible, the service life of the stirring shaft is affected, and the elements precipitated from the material of the stirring shaft itself may pollute the molten meta...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a rotary stirring type rare earth alloy smelting device, which mainly solves the problem that the rare earth metal smelting device uses a stirring shaft to stir, which causes the molten metal to be easily polluted and difficult to clean up in the later stage
