What is the aluminum ingot smelting
Aluminum is a commonly known as recovery. Aluminum is a chemical element. Its chemical symbol is Al, and its atomic number is 13. Aluminum is the third largest in the earth's crust, second only to oxygen and silicon, and is the most abundant metal element in the earth's crust. Among the metal varieties, second only to steel, they are the second major metals. Until the end of nineteenth Century, it has become the competitive aluminum made in the engineering application of the metal, and come into fashion. Aluminum is widely used in construction, automotive, aviation, the development of three major industries, the unique properties of material properties of aluminum and its alloys, which greatly facilitates the production and application of recycled aluminum metal.
Concrete method: heating to melt state, through a variety of physical and chemical methods, last year after impurities, made of various grades of aluminum, pouring into aluminum ingot.
The scrap recycling processing method: heavy media beneficiation method: using gravity separation method of heavy medium density greater than aluminum copper and other heavy metals, the use of aluminum density than other non-ferrous metal scrap to small principle, floating in the medium, and heavy non-ferrous metal sink to the bottom, to the purpose of separation. But the key to technology is to screen a medium of density greater than aluminum and less than copper, which is not water or any other liquid, but definitely a fluid. The fluid in the reciprocating motion work, aluminum floating are separated in the medium above. Parabolic beneficiation: the use of different kinds of basically the same object, when the same force was thrown, the different placement of the principle, you can waste aluminum scrap density of different kinds of waste non-ferrous metal separation. With the same force along the line to shoot different density and volume of the same basic object, all kinds of objects moving in parabolic direction, landing in different positions. The most simple experiments can be carried out at the level of the conveyor belt, when the waste on the conveyor belt with high speed, when to the end, the scrap aluminum is thrown along a straight line, due to a variety of different gravity waste, were landing at different points, so as to achieve the purpose of sorting of scrap aluminum. This method can make the aluminum, copper, lead and other waste evenly. The equipment manufactured according to this principle has been adopted abroad, and it is still in the research stage in china.
