To understand what is the aluminum casting process, we must look at the performance of aluminum. Aluminum is the richest metal element in the crust, which forms nearly 8%. It is always used as a compound, and some of its minerals are bauxite, cryolite, corundum, aluminite, crystal stone, turquoise, spinel and silicates such as kaolin, feldspar and mica. Bauxite is a kind of iron aluminum hydroxide, aluminum is the production of basic raw materials.
Chemical impurities are removed from the bauxite to produce alumina (alumina). The bauxite is pulverized, mixed in a caustic soda solution, and then heated under steam to dissolve the alumina under pressure. Precipitate and filter to remove impurities. After cooling, the solution was stirred to form hydrated alumina crystals. The crystals were washed and then dried in a long rotary kiln. The final product, alumina or alumina, is a very hard crystalline material with a refined sugar appearance. Four pounds of bauxite produces about 2 pounds of alumina.
Aluminum light, high strength, good thermal conductivity, high reflectivity, good corrosion resistance, good processing, beautiful appearance. Can almost give any finish. It is non-magnetic, non-toxic, sparkless.
The high thermal conductivity of aluminum is a significant advantage in any application that requires fast and uniform conduction or dissipation of heat. On the basis of weight, aluminum is the most effective thermal conductor for ordinary metals.
Electrolyzing the alumina solution in the molten fluoride to aluminum; the electrolysis occurs in the reducing tank or the cell of the reducing device. Aluminum reduction plant production of pure, high-quality aluminum. The reduction process removes oxygen from the alumina, which consists of almost equal aluminum and oxygen, leaving pure aluminum. Two pounds of alumina produce one pound of aluminum.
