铝及其合金在加工制造过程中，企业往往会对金属表面进行处理，喷涂各种涂料或包覆各种有机（无机）材料等，其中可能会加入酸、碱、盐和油等物质。

In the process of manufacturing and manufacturing of aluminum and its alloys, enterprises often process metal surfaces, spray various coatings or cover various organic (inorganic) materials, etc., which may include acids, alkali, salt and oil.

因此，铝及其制品在使用或消费之后进入报废领域，其本身就带有污染物。此外，废铝来自社会各个角落，种类繁多，在回收和拆解过程中受到过不同程度污染，会夹杂各种非铝物质，这些夹杂物也会在熔炼过程中发生物理和化学反应，对环境产生一定的影响。

Therefore, after the use or consumption of aluminum and its products into the waste field, it itself has a pollutant. In addition, scrap from every corner of the society, variety, have varying degrees of pollution in the recycling and dismantling process, will be mixed with a variety of non aluminum material, these inclusions will produce physical and chemical reaction in the smelting process, have a certain impact on the environment.

因此，应该重视废铝的预处理，使夹杂的污染物消灭在熔炼之前。预处理技术主要包括：分选，即分选出塑料、橡胶等非铝物质；洗涤，即洗掉废铝中的油污等物质；脱漆，为减少废铝表面涂层不完全燃烧产生的污染，应注重涂层废铝在入炉之前的脱漆处理。

Therefore, attention should be paid to the pretreatment of aluminum scrap, the inclusion of pollutants nipped in before smelting. The pretreatment technology mainly includes: sorting, namely choose plastic and rubber non aluminum material; washing, wash the scrap in oil paint, reduce material; aluminum surface coating pollution caused by incomplete combustion, should pay attention to in the paint coating scrap into the furnace before treatment.

预处理的同时，也分离出了各种非铝物质，得到了纯净的废铝，这亦是熔炼高质量铝合金的必要保障。由于大量的夹杂物已经在熔炼之前去掉，因此减少了添加剂的用量，缩短了熔炼周期，生产成本相应下降，这就显示了环境管理的优势。

The pretreatment at the same time, also isolated various non aluminum material, the pure aluminum, it is also necessary to ensure the high quality of the Aluminum Alloy smelting. Because a large number of inclusions have been removed before smelting, the amount of additives is reduced, the smelting cycle is shortened, and the production cost decreases accordingly, which shows the advantages of environmental management.
