Abstract The energy-saving potential for different low carbon ironmaking approaches was investigated facing to the given conditions of materials. The result shows that for the general BF, when the indirect reduction approaches to the chemical balance, the gas utilization can reach up to 56.99% and fuel ratio is decreased by 28.37kg/t. For oxygen blast furnace, when the top gas is totally recycled the fuel ratio can be reduced to 385.6kg/t. The fuel ratio can also be reduced through the injection of coke oven gas. About 5.0kg/t coke ratio can be saved by every 10m3 COG injection. Along with the oxygen enrichment being improved, the optimal injection volume corresponding to the minimal fuel ratio increases and as a result the lowest fuel ratio decreases. When the oxygen enrichment is 6%-8% and injection volume is 160-180m3/t. the coke ratio can be reduced maximally by 53-54kg/t. Using high reactivity coke in blast furnace can decrease temperature of thermal reservation zone and the balance concentration of CO decreases accordingly. When the balance concentration of CO is decreased by the step of 2.5% from 70%-60%, the fuel ratio can be reduced by 10.30-12.20kg/t theoretically and the reducing rate decreases.
