Abstract:The experiments of preparation of Al-Si alloys by electrothermal process were carried out respectively in 20 kW, 100 kW and 1800 kW DC arc furnaces. The mechanism of furnace bottom rise was studied. It was found that the bottom rise can be divided into three types, including the low bottom temperature, abnormal reducing reaction and carbide deposition. The furnace bottom rise is related to the carbon ratio of the briquet, the heating speed of the briquet and the parameters and operation of furnace.
Key words: aluminum-silicon alloy; electrothermal smelting; furnace bottoms; rise;direct current arc furnace
