Problems solved by technology

Although the content of aluminum in nature is relatively high, it is a non-renewable element after all, and the mining of aluminum in nature is not only complicated, but also causes damage and pollution to the environment
Relatively speaking, there is a large amount of scrap aluminum every year, which is another considerable amount of aluminum resources. However, the current recycling efficiency of scrap aluminum is not high, which undoubtedly causes a lot of waste of aluminum resources, which is not conducive to improving The recycling rate of aluminum resources and the reduction of the production cost of aluminum resources

Abstract

The invention provides an aluminum ingot casting method based on the waste aluminum materials. The waste aluminum materials can be accurately and fully classified, and therefore aluminum elements in different chemical forms can be recycled in a centralized mode to the maximum extent; in addition, targeted chemical reaction treatment can be conducted according to the chemical forms of the aluminumelements, so that an aluminum base alloy melt is obtained, and finally the aluminum base alloy melt is cured and formed in a two-time discrete casting mode to obtain an aluminum ingot with a double-layer structure; therefore, the internal structure of the aluminum ingot is optimized, strain cracks of the aluminum ingot in the casting process are avoided, and the quality of the aluminum ingot is improved to the maximum extent.

Description

technical field [0001] The invention relates to the technical field of aluminum ingot production technology, in particular to an aluminum ingot casting method based on scrap aluminum materials. Background technique [0002] Aluminum alloy is widely used in different occasions due to its light weight and high mechanical strength. At present, aluminum ingots are mainly used as raw materials for the production of aluminum alloys. Although the content of aluminum element in nature is relatively high, it is a non-renewable element after all, and the mining of aluminum element in nature is not only complicated, but also causes damage and pollution to the environment. Relatively speaking, there is a large amount of scrap aluminum every year, which is another considerable amount of aluminum resources. However, the current recycling efficiency of scrap aluminum is not high, which undoubtedly causes a lot of waste of aluminum resources, which is not conducive to improving The recycl...
