Embodiment Construction
[0020] The specific embodiment of the present invention is described further below:
[0021] A kind of application of rare earth in scrap aluminum secondary casting aluminum alloy, comprises the following steps:
[0022] 1) scrap aluminum;
[0023] 2) Category sorting;
[0024] 3) Classification preprocessing;
[0025] 4) classification remelting;
[0026] 5) Proportioning into the furnace;
[0027] 6) Add rare earth;
[0028] 7) Fine sorting: fuel oil double chamber reverberatory furnace;
[0029] 8) Composition analysis;
[0030] 9) Casting;
[0031] 10) Rare earth casting aluminum alloy ingots.
[0032] The classification pretreatment is to pretreat the five types of waste aluminum respectively, first crushing, magnetic separation, removing plastic rubber and other foreign matter, and washing and removing the surface with paint and paint with dilute hydrochloric acid, and then classifying, compacting and packing.

The invention relates to the field of aluminum alloy casting, in particular to application of tombarthite to scrap aluminum regeneration cast aluminum alloy. The application comprises the following steps including 1) collecting of scrap aluminum; 2) category sorting; 3) classification pretreatment; 4) classified remelting; 5) inputting of the scrap aluminum into a furnace according to a matching principle; 6) adding of the tombarthite; 7) refining by means of a fuel oil double-chamber reverberatory furnace; 8) component analyzing; 9) casting; and 10) casting of aluminum alloy ingots by means of the tombarthite. The technology is novel, reasonable in technological process, good in regenerated product quality and obvious in social and economic benefit and conforms to the nation technology policy, currently, no related research result has been reported in the country, and the technology holds a leading position in the country.
Description
technical field [0001] The invention relates to the field of aluminum alloy casting, in particular to the application of a rare earth in recycling aluminum alloy casting from waste aluminum. Background technique [0002] my country is endowed with unique rare earth resources, but the development, research and popularization and application are far from enough. Since rare earths have some unique functions in the metal smelting process, the research and development potential of applied alloys is huge. In recent years, various rare-earth aluminum alloys have been successfully launched in my country, which have Chinese characteristics. Among them, the research and development of rare-earth electrical aluminum and rare-earth medium-high-strength deformable aluminum alloys has attracted worldwide attention. [0003] Due to the low ratio of aluminum to silicon in China, the difficulty of mining and metallurgy, and the high energy consumption, my country's aluminum ore has a relati...
