Abstract

The invention discloses an anti-oxidant aluminum alloy additive. The anti-oxidant aluminum alloy additive comprises the following raw materials in parts by weight: 70-80 parts of metal powder, 5-8 parts of an anti-oxidant, 10-25 parts of a binder and 1-2 parts of a stabilizer, totaling 100 parts. The anti-oxidant is composed of calcium powder, beryllium powder and rare earth metal, and the weightratio of the calcium powder to the beryllium powder to waste rare earth polishing powder is 5:(0.01-0.02):2. The Calcium powder, the beryllium powder and the waste rare earth polishing powder are creatively used as anti-oxidants according to a set component proportion and proportion and are combined with other raw material components to form the aluminum alloy additive with a good anti-oxidant effect, and a casting obtained after application is smooth in surface, few in cracks and bubbles and stable in product quality.

Description

technical field [0001] The invention relates to the technical field of aluminum alloy processing, in particular to an anti-oxidation aluminum alloy additive. Background technique [0002] Aluminum alloy is formed on the basis of pure metal smelting, plus other alloy elements, and most of the industrial pure metals of aluminum alloy come from smelters, such as industrial pure aluminum, etc. are all made from electrolysis factories, and these so-called In pure metals, impurities are still unavoidable. For example, the primary aluminum ingot still contains two main impurities, iron and silicon. These two impurities are mostly brought from aluminum ore, which is the raw material for aluminum smelting. Performance has a great influence, so when using primary aluminum ingots, the choice of metal taste is extremely important. At the same time, in the existing aluminum alloy smelting, the traditional method is to use the intermediate alloy to adjust the chemical composition, becaus...
