Scrap aluminum smelting
2024-05-21
Reclaimed aluminum smelting equipment, also called aluminum melting furnaces, includes a reflection furnace, induction furnace, resistance furnace, etc. Strictly speaking, the smelting equipment of recycled aluminum is the same as raw aluminum. However, because the shape and size of waste aluminum are different, the burning loss of the small-size material is significant, and it has not even been melted in the furnace, that is, it has been oxidized. Therefore, it is necessary to consider the oxidation burning loss and various requirements for the equipment for melting waste aluminum. Although the melting point of aluminum is relatively low (660℃), its latent heat and specific heat of melting are large, so the heat required for aluminum melting is even higher than that of copper (963℃), indicating that energy saving in aluminum smelting is very important. The aluminum melting furnace has a reflection furnace, induction furnace, resistance furnace, and so on. Reflective furnace and radial and convection-flow aluminum melting furnace. The fuel used in the reflector is natural gas, coal gas, heavy oil, and so on. According to the geometric form, there are side-loading rectangular furnaces and top-loading circular furnaces, etc. In addition to resistance furnaces, the application of reflection furnaces and induction furnaces...
