Therefore, attention should be paid to the pretreatment of scrap aluminum so that the contaminated impurities are destroyed before smelting. Pretreatment technologies mainly include: sorting, that is, sorting out non-aluminum materials such as plastics and rubber; washing, that is, washing out oil and other substances in scrap aluminum; removing paint, in order to reduce pollution caused by incomplete combustion of surface coatings of scrap aluminum. Attention should be paid to the paint stripping of the coated aluminum scrap before it is introduced into the furnace.
At the same time as the pretreatment, various non-aluminum materials were also separated and pure aluminum scrap was obtained, which is also a necessary guarantee for smelting high-quality aluminum alloys. As a large number of inclusions have been removed before smelting, the amount of additives is reduced, the smelting cycle is shortened, and the production costs are reduced accordingly, which shows the advantages of environmental management.
Scientifically choosing fuel science to economically select fuels can not only reduce energy consumption but also significantly change the environment. From the current point of view, liquid fuels have better environmental benefits than solid fuels and have higher combustion efficiency; gas fuels have better environmental benefits than liquid fuels and better combustion efficiency. Therefore, when selecting fuels, gas fuels should be used as much as possible. However, due to conditions, gas fuels cannot be used anywhere. At present, many reclaimed aluminum companies have established gas generators that convert solid fuels into gaseous fuels. This not only greatly reduces the pollution brought about by coal combustion, but also reduces the production costs due to the increase in combustion efficiency. This is undoubtedly a science. s Choice.
The additives used in the aluminum industry are recycled without additives that affect the environment, mainly solvents (covering agents) and refining agents. From the various additives currently used, chlorine, hexachloroethane, Zinc chloride and so on. The use of chlorine to refine aluminum melts is rare, but there are applications in some special alloys. Hexachloroethane and zinc chloride are also used. Some manufacturers produce non-toxic refining agents containing large amounts of hexachloroethane. It is recommended that companies choose additives that do not pollute the environment, such as inert gases or nitrogen.
Improve the processing technology of aluminum ash The content of aluminum in aluminum ash is relatively high and must be recycled. In order to avoid pollution from recycling aluminum from aluminum ash, it is recommended that companies with a size use rotary kiln to treat aluminum ash, or press mills to recover aluminum in aluminum ash, so that the pollution caused by the treatment of aluminum ash is reduced to a low level.
Excellent balance: the balance is important when polishing. The reinforced inner structure keeps the plate stable and smooth. High-quality material and advanced production technology ensure the pad balance.Resistance to heat, and reducing heat transfer to the paint surface.The better balanced a backing pad is, the less fatigue you feel when polishing or waxing car.The Velcro backing has extra gripping power and it is strong.works well and has not shown any sign of wear after about 50 hours of use.Backing pads are Widely used in grinding and polishing artificial stone, furniture and wood products, metals, cars and other items.
