Recycling scrap aluminum can not only reduce the mining of alumina ore and the manufacture of electrolytic aluminum, thereby reducing the consumption of natural resources and reducing environmental damage to nature, but also improve resource utilization and reduce production costs.
[0003] After the scrap aluminum is recycled, it is smelted in a smelting furnace to form molten aluminum. However, molten aluminum has the characteristic of absorbing gas, and hydrogen is the only gas that can have a certain solubility in molten aluminum. Under melting conditions, molten aluminum reacts with moisture to produce hydrogen, which will affect the quality of molten aluminum casting. Therefore, the molten aluminum needs to be degassed.
