ABSTRACT An object of the invention is to provide a method of manufacturing aluminum alloy by effectively using the aluminum residuum containing a low percentage of metal aluminum as industrial wastes. As the component ratio of a briquette of aluminum residuum, a mass of silica rock and a mass of anthracite, the weight percentage of Al2O3:SiO2:C=40:33:27 is maintained. The blending having a maintained weight percentage is continuously introduced into the electric furnace for producing carbide. The electric furnace is provided with three self-baking electrodes having a diameter of 1400mm, and a transformer capacity of 30,000KVA. While the electrodes are embedded at the depth of about 1m and the temperature in the electric arc range is kept between 2200°C and 2400°C, the melting reduction is carried out. When 170 tons of aluminum residuum briquette were completely introduced into the electric furnace, 100 tons of Al-Si-Fe alloy were obtained. The aluminum alloy can be used as deoxidizer or temperature raising agent in the iron and steel manufacture with variously developed manufacture processes and needs.
