Remelted scrap aluminium alloy window aluminum rod of 1 tons can sell how much money.
Aluminum Alloy smelting process is as follows: charging, melting (with copper, zinc and silicon etc.), slag, magnesium, beryllium and other, stirring, stirring, sampling, regulation of components, refining slag, converter refining, modification and static casting.Paint coating, aluminum ware: furnace oil surface and other pollutants, the organic solvent such as acetone cleaning, if still not clear, it should be used in paint paint furnace. The maximum temperature of the paint stripper should not exceed 566 degrees. As long as the waste material stays in the furnace for enough time, the general oil and coating can be removed.Smelting furnace and refining furnace: the main equipments of the recycled aluminium are smelting furnace and refining purifying furnace. China's largest aluminum recycling enterprise is located on the outskirts of Shanghai Shanghai Sigma Metals Inc, the company has two sets of 50t melting holding furnace, a set of 40t fuel melting holding furnace; fuel rotary furnace of a 12t. Small enterprises may use pool kilns, crucible kilns and other smelting.
Alloy furnace: iron is the harmful substance in aluminum and its alloy, and it has the greatest influence on the mechanical properties of aluminum alloy. Therefore, the scrap iron in miscellaneous aluminium should be selected in the pretreatment process to the maximum extent. By separating the magnetic separation of iron and steel scrap and further processing, because there are combined mechanical parts of aluminum based non-ferrous metal scrap iron and steel in some devices, it is difficult to separate, such as nuts, scrap pieces of wires, keys, plumbing parts, small gear, it is necessary for the separation of this part, because separation of nonferrous metals can improve and enhance the value of scrap iron and steel grades, but the separation is difficult, generally use the manual dismantling and sorting, but low efficiency. In order to improve the production efficiency, the most effective way to deal with the difficult to disassemble parts of aluminum and steel is to heat them in a special melting furnace to make the aluminum melt out of the waste steel.Casting homogenizing furnace: controlling the quality of aluminium profile by controlling the alloy composition of aluminium ingot. Adopting the advanced proportional heating and temperature control system, the temperature difference is small, the casting adaptability and component segregation of the aluminum rod are eliminated completely, and the plasticity and the strength of the alloy are greatly improved.
