Problems solved by technology

[0002] During the smelting process of aluminum and aluminum alloys, the composition of aluminum alloys is mainly adjusted by adding metal additives such as titanium, copper, manganese, and iron. Due to the accelerated melting of metal additives, a large amount of smoke is generated during use, which pollutes the environment and affects the health of operators. After the aluminum alloy is smelted, a certain amount of slag agent and refining agent need to be added to remove the inclusions and gases, increasing production costs

Abstract

The invention discloses a novel metal composite additive for aluminum alloy smelting and a preparation method of the additive. The novel metal composite additive for aluminum alloy smelting comprisesthe following raw materials in percentages by mass: 70-80% of metal powder, 1-3% of high-grade stearic acid, and the balance of a fluxing agent, wherein the sum of all components is 100%. The preparation method comprises the following steps: uniformly mixing the raw materials according to the formula ratio, and performing compression moulding to obtain the target product. A formula of the fluxingagent in the metal additive is changed, so that when the metal additive has the effect of refining and slag removal on molten aluminum while adding metal elements, and can effectively remove inclusions and gases in the molten aluminum, improve the microstructure of an ingot after aluminum alloy smelting, and realize the organic combination of metal element addition, slag removal and refining.

Description

technical field [0001] The invention belongs to the technical field of metallurgy, and in particular relates to a novel metal compound additive for smelting aluminum alloys and a preparation method thereof. Background technique [0002] In the aluminum alloy smelting process, the composition of the aluminum alloy is mainly adjusted by adding metal additives such as titanium, copper, manganese, and iron. Due to the accelerated melting of metal additives, a large amount of smog is produced during use, which pollutes the environment and affects the health of operators. After the aluminum alloy is smelted, a certain amount of slag agent and refining agent need to be added to remove the The inclusions and gases increase the production cost. Therefore, it is very necessary to develop a product that can solve the above-mentioned technical problems. Contents of the invention [0003] The first purpose of the present invention is to provide a novel metal composite additive for al...
