[China Aluminum Industry Network] 1 single species of aluminum scrap Such scrap aluminum is generally a certain type of waste parts, such as pistons of internal combustion engines, automobile speed reducer casings, automobile wheels, and front and rear automobile safety catches. Aluminum doors and windows. These aluminum scraps have been categorized clearly at the time of import and are of a single variety and are imported in bulk. Therefore, they are high-quality recycled aluminum raw materials. 2 scrap aluminum section The waste aluminum scraps, also referred to as slices, are high quality aluminum scraps. The reason why it is called slicing is that many developed countries use mechanical methods to break up scrapped automobiles, waste equipment and various types of waste household appliances into scraps, and then the quality of scrap aluminum chips is better than other scrap aluminum. The price is expensive, it is suitable for large-scale modern enterprises, and it is very difficult to purchase in the international market. Therefore, in addition to self-owned or joint-venture companies themselves importing, China's general recycled aluminum plants rarely use such waste. After mechanized sorting, the scrap aluminum that was sorted out was aluminum scrap. In addition, when the recycling department reprocesses some large-volume scrap aluminum parts, it is also broken into scraps by crushing. Such scraps are also called scrap aluminum chips. The scrap aluminum chips are easy to transport and easy to sort. The texture is relatively pure and is also a good quality aluminum scrap material. At present, in the scrap aluminum trade in the international market, the slice has a relatively large share, and various types of slices are being standardized. As for the components of slicing, it is generally divided into several grades, among which the high-grade slicing is a relatively pure mixture of various aluminum scraps and their alloys. The vast majority of smelting is performed without any treatment, and a small amount of grades Low sections contain different amounts of other impurities, generally containing 80% to 90% of waste aluminum, of which impurities are mainly non-ferrous metals such as scrap steel and scrap copper, and also contain a small amount of waste rubber, etc. Pure waste aluminum material. Scrap aluminum smelting is also relatively easy. When smelting, it is convenient to enter the furnace, easy to get rid of impurities, less flux consumption, high metal recovery rate, low energy consumption, processing costs are low, very popular with users, generally large-scale recycled aluminum plants are sliced main ingreadient. High-quality aluminum scrap is more expensive than other aluminum scraps, and it is suitable for large-scale modern enterprises. It is difficult to obtain in the international market. Therefore, in China, except for wholly-owned or joint-venture enterprises, the recycled aluminum plant rarely uses such scrap. . 3 mixed scrap aluminum material This type of waste aluminum is complex in composition and has different physical shapes. In addition to aluminum scrap, it also contains a certain amount of scrap steel, waste lead, scrap zinc and other metals and waste rubber, waste wood, plastic waste, stones, etc. Waste aluminum and scrap steel machinery are combined together. Such scrap components are complex. A small amount of scrap aluminum is large and the surface is clear and easy to sort. Such scraps must be pre-sorted before being smelted, that is, scraps and other impurities are manually picked. 4 Incineration of aluminum-containing materials This type of aluminum material is a type of aluminum-containing waste material with a relatively low grade, and is mainly a crushed material of various kinds of scrapped household appliances, etc., and a part of the scrap material is selected and then burned to form a material. The purpose of incineration is to remove combustible materials such as waste rubber and waste plastics. Such aluminum-containing waste generally has an aluminum content of about 40% to 60%, and the rest are mainly non-ferrous metals such as garbage (bricks and stones), scrap steel, and extremely small amounts of copper (copper wires). Aluminum is generally less than 10 cm in size. During the incineration process, some aluminum and low-melting substances such as zinc, lead, and tin all melt, and form glassy materials with other materials, which are difficult to distinguish with the naked eye and cannot be classified. . 5 mixed shredded aluminum scrap This kind of scrap is a low-grade aluminum scrap, and its composition is very complex. It contains 40% to 50% of various scrap aluminum. The rest is scrap steel, a small amount of lead and copper, a lot of garbage, stones and soil, waste Plastics, waste paper, etc., soil accounted for about 25%, scrap accounted for 10% - 20%, stone accounted for 3 - 5%.
