Embodiment 1

[0037] A rare earth aluminum alloy production device for metallurgy, comprising an aluminum bag 2 and a vacuum chamber 4 connected in sequence, wherein the aluminum liquid 1 is stored in the aluminum bag 2, the guide tube 5 communicates with the aluminum liquid 1 and the vacuum chamber 4, and the vacuum chamber 4 An electromagnetic induction heating container 6 is provided, and a feeding bin for rare earth bulk materials is provided above the vacuum chamber 4. A continuous casting buffer container 15 is provided at the outlet of the electromagnetic induction heating container 6 in the vacuum chamber 4, and the continuous casting buffer container 15 is sequentially It is connected with the continuous casting machine 16 and the rolling unit 18 outside the vacuum chamber 4 .

[0038] The upper layer of the aluminum liquid 1 is a covering agent 3 (also known as mold slag), one end of the guide tube 5 is located in the aluminum liquid 1 below the covering agent 3, and the other end ...

Embodiment 2

[0043] A method for producing rare earth aluminum alloys for metallurgy, comprising the following steps:

[0044] ①Adding aluminum: molten aluminum (1) enters the electromagnetic induction heating container (6) in a decompression and cooling environment;

[0045] ② Rare earth addition: Add rare earth bulk material (10) into the electromagnetic induction heating container (6) in a vacuum environment;

[0046] ③ Alloy homogenization: through electromagnetic induction heating, the rare earth bulk material (10) is gradually melted, the aluminum liquid (1) is mixed with the rare earth bulk metal, and finally an alloy liquid (14) with a relatively uniform composition is formed;

[0047] ④ The alloy liquid is poured into the continuous casting buffer container (15) from the electromagnetic induction heating container (6) at one time, and the alloy liquid (14) is formed into a trapezoidal cross-section aluminum rod through the continuous casting machine, or rolled into a cross-section...

Embodiment 3

[0050] A specific operation method for the production of rare earth aluminum alloys for metallurgy, comprising the following steps:

[0051] ① Aluminum liquid 1 is stored in aluminum bag 2. In the aluminum package 2, the lower layer is the aluminum liquid 1, and the upper layer is the covering agent 3. When the vacuum chamber 4 reaches a certain degree of vacuum, the aluminum liquid 1 is transferred to the vacuum chamber 4 through the guide tube 5, and enters the electromagnetic induction heating container 6. After the aluminum liquid in the electromagnetic induction heating container 6 reaches a certain volume, the aluminum ladle is moved The lifting device 21 and the guide tube supporting device 22 adjust the relative positions of the aluminum bag 2 and the guide tube 5, and stop adding the aluminum liquid 1.

[0052] ② When both the silo valve 7 and the feeding vacuum valve 8 are closed, open the feeding cover 9 and put the rare earth bulk material 10 into the upper feedin...

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...
