The experiments on charging sponge iron for electric arc furnace steelmaking show that sulphur content in molten steel obviously drops down and time of purifying molten steel and charging time shorten with stable power supply 630.3 ̄719.5 kwh/t. Meanwhile,the absorption ratio of sponge iron arrives at 85.5% and the ratio increases with the rise of iron content and metalation ratio. Smelting experiments also prove that sponge iron is more applicable to smelt high-grade steel and pure steel. Also it is importart to choose steelmaking material in order to make sure to improve the steel quality and smelting index. Smelting process should be developed in accordance with the characteristic of sponge iron.
