A kind of rare earth aluminum alloy production device for metallurgy

Abstract

The invention discloses a rare-earth aluminum alloy production device for metallurgy, which comprises an aluminum bag and a vacuum chamber connected in sequence, wherein the aluminum liquid is stored in the aluminum bag, the guide tube is connected to the aluminum liquid and the vacuum chamber, and electromagnetic induction heating is arranged in the vacuum chamber For the container, there is a feeding bin for rare earth bulk materials above the vacuum chamber, and a continuous casting buffer container is provided at the outlet of the electromagnetic induction heating container in the vacuum chamber, and the continuous casting buffer container is connected with the continuous casting machine and the rolling unit outside the vacuum chamber in turn. The invention realizes the feeding of the aluminum element and the rare earth element in a vacuum environment, and solves the phenomenon that the aluminum element and the rare earth element are easy to absorb gas and oxidize. The rare earth wire produced by the device has the characteristics of easy storage and strong process adaptability.

Description

technical field [0001] The invention relates to the technical field of metallurgy, in particular to a rare earth aluminum alloy production device for metallurgy. Background technique [0002] As "industrial vitamins", rare earth elements are widely used in many fields such as materials, petrochemicals, textiles, and agriculture. The addition of a proper amount of rare earth to steel has three main functions: purification of molten steel, modification of inclusions, and microalloying, which can improve the toughness and plasticity of steel, especially the transverse impact toughness, and improve the anisotropy of steel; for example, rare earth can make high-hardness alumina The inclusions transform into spherical sulfur oxides and aluminate rare earths, which significantly improve the fatigue resistance of steel; the segregation of rare earths at grain boundaries can inhibit the segregation or Form compounds with higher melting point with these impurities, purify and strengt...
