Problems solved by technology

However, at present, most of the waste aluminum in my country is mainly used for low-value-added cast aluminum alloys for recycled hardware products. The alloy elements such as silicon, copper, magnesium, and zinc contained in waste aluminum have not been effectively utilized, resulting in a huge waste of resources.

Abstract

Disclosed is an aluminum scrap recovery method of cast aluminum alloy. The aluminum scrap used in the method comprises 20-45% of waste aluminum automobile engine cylinder, 15-35% of waste motorcycle wheels, 10-30% of waste aluminum scrap, and 10-25% of waste electrical heating plate, the balance of aluminum alloy die-casting waste. The method uses the waste aluminum as the main raw material to improve the use value of the scrap aluminum and reduce the production cost of the cast aluminum alloy by optimizing the composition of the waste aluminum raw material directly to reproduce the high performance cast aluminum alloy, and the high performance cast aluminum alloy produced can be used for the automotive and motorcycle field and other fields, and has a broad application prospect.

Description

technical field [0001] The invention belongs to the technical field of alloy preparation, and in particular relates to a waste aluminum recycling method for casting aluminum alloys. Background technique [0002] Cast aluminum alloy is an aluminum alloy that can directly obtain parts by casting forming process. Cast aluminum alloy is currently the most widely used type of non-ferrous metal structural material, and is widely used in household appliances, hardware, automobiles, motorcycles, ships, mechanical equipment and other fields. With the rapid development of my country's economy and society, the demand for high-performance cast aluminum alloys is increasing. [0003] A literature search found that the existing technology mainly uses primary aluminum as a raw material, and alloy elements such as silicon, copper, magnesium, and zinc are added during the melting and casting process to prepare cast aluminum alloys. As we all know, primary aluminum is obtained by the electr...
