Abstract：Mathematical model of blast furnace ironmaking process using pre-reduced burden was established . The iron grade of raw material , metallization rate of pre-reduced iron ore and combined form of iron effect on energy consumption of blast furnace was calculated. Energy consumption of blast furnace ironmaking using pre-reduced burden between traditional blast furnace was compared. The results show that according to different iron grade of raw material, there is a suitable metallization rate of pre-reduced burden, make the lowest coke ratio of blast furnace smelting. If the iron in the pre-reduced burden is in the form of iron silicate, the blast furnace coke ratio is high because iron silicate direct reduction is strongly endothermic reaction. Blast furnace ironmaking process using pre-reduced burden can greatly reduce coke ratio, but increase fuel consumption.
