Description
Technical Field
The invention relates to the technical field of metallurgy, in particular to a production device of rare earth aluminum alloy for metallurgy.
Background
The rare earth element is used as an industrial vitamin and is widely applied to a plurality of fields of materials, petrifaction, light spinning, agriculture and the like. The addition of a proper amount of rare earth into steel has three main functions: purifying molten steel, modifying inclusion and microalloying, improving the toughness and plasticity, particularly the transverse impact toughness of the steel and improving the anisotropy of steel; for example, the rare earth can lead high-hardness alumina to be mixed and converted into spherical oxysulfide and rare earth aluminate, thereby obviously improving the fatigue resistance of the steel; the segregation of the rare earth in the grain boundary can inhibit the segregation of phosphorus and sulfur and low-melting-point impurities of lead, tin, arsenic, antimony and bismuth in the grain boundary or form compounds with higher melting points with the impurities, purify and strengthen the grain boundary, eliminate the harmful effect of the low-melting-point impurities, and be beneficial to improving plasticity, particularly high-temperature plasticity and the like. After the rare earth is applied to the steel, the effects of refining impurities, deeply purifying molten steel and strongly microalloying can be achieved, the toughness, plasticity and fatigue life of the steel are obviously improved, and the steel is more tough, heat-resistant, wear-resistant and corrosion-resistant.
The wire-feeding method is a method in which a relatively suitable rare earth is added to molten steel. At present, a plurality of experimental researches on rare earth addition processes are carried out at home and abroad, and the mass production is realized under respective historical conditions, which mainly comprise the following steps: the method comprises eight methods, namely a large-ladle throwing method, a large-ladle pressing-in method, a method for blowing rare earth powder into a ladle, a method for feeding wires by using a casting injection center injection pipe, a method for hanging rare earth metal rods in a mould, a method for feeding wires by using a steel ladle, a method for feeding wires by using a tundish, a method for feeding wires by using a crystallizer and the like. The currently used methods mainly focus on: a ladle wire feeding method and a crystallizer wire feeding method. Wherein the crystallizer wire feeding method has the advantages of high yield and stable process.
Pure rare earth filaments are easily oxidized. At normal temperature, pure rare earth metal is easy to react with oxygen in the air to generate rare earth oxide on the surface, and part of rare earth oxide is easy to pulverize and is continuously exposed to the fresh surface to react with oxygen again to oxidize. The larger the specific surface area of the pure rare earth wire, the more rare earth elements are oxidized by contacting oxygen in the air. Therefore, the preservation of rare earth filaments is a weak point limiting the wide application thereof. When the catalyst is added, the ambient temperature above the molten steel is higher, and the oxidation rate is higher; at a certain molten steel depth, even boiling occurs due to the vaporization of rare earth metals.
The rare earth aluminum alloy provided in the patent application entitled rare earth foamed aluminum material (201610836686.7) is not suitable for use in the metallurgical industry, and the continuous production of the rare earth aluminum alloy cannot be realized by the method provided in the patent application entitled method for preparing rare earth-containing aluminum alloy (201610732657.6), the patent application entitled aluminum-silicon rare earth alloy ingot (201610141648.X) and the method provided in the patent application entitled rare earth foamed aluminum material (201711254396.2), and the like.
Therefore, in the continuous casting production, a continuous industrial production device capable of producing metals containing rare earth elements, which are easy to store and have strong technological adaptability, especially rare earth alloy rods or rare earth alloy wires which are convenient to add is needed.
Disclosure of Invention
The invention provides a production device of rare earth aluminum alloy for metallurgy, which realizes vacuum charging of aluminum element and rare earth element; the phenomenon that aluminum elements and rare earth elements are easy to absorb air and oxidize is solved, and the method is easy to realize; can also be used for producing rods or wires of rare earth aluminum-iron alloy, rare earth aluminum-silicon alloy, rare earth aluminum-barium alloy and other similar alloys. The rare earth filament produced by the method has the characteristics of easy preservation and strong technological adaptability.

Under the same molten steel condition, the deoxidation capability of the metal elements is in the following order from strong to weak: ca, Mg, RE (rare earth element), Al, Ti, B, Si, C, V, Cr, Mn.

In order to realize reasonable and economic use of the rare earth elements, alloying the rare earth elements to form the rare earth alloy wire is a good way. On the other hand, Ca and Mg have larger vapor pressure at high temperature, and have certain difficulty in storage. Comprehensively considered, the rare earth element and the aluminum element are mixed to form the rare earth aluminum metal wire, which is beneficial to the storage, addition and use of the rare earth element.
The addition of a proper amount of rare earth into steel plays a beneficial role, but when excessive rare earth is added into molten steel, the addition of excessive rare earth is counterproductive, so that the performance of the steel cannot be improved, the normal production of steel is influenced, and even the scrapping of materials is caused. Because of the influence of price, rare earth is not suitable to be used as a pre-deoxidation and desulfurization agent, so that the rare earth aluminum alloy is required to use aluminum element as a main deoxidation and desulfurization agent, and the content of the rare earth element is not suitable to be too high.
