Abstract：A domestic large blast furnace was taken for the research object, and the main goal of the research was tapping the potentialities and reducing the consumption. By taking advantage of the calculating method of the Rist operating line, the actual and ideal Rist operating lines were drawn according to the actual production data of the blast furnace. So on this basis, the potential of reducing the coke ratio and the quantitative influence of CO2 mass fraction in the gas on the coke ratio were also further calculated and analyzed. According to the blast furnace actual producing situation, the optimized charging system was adopted to improve the gas flow distribution, which refined the unique center gas flow to the center gas flow accompanied with the edge gas flow. Practice had proved that the gas utilization rate was improved by 2% and reduced the coke rate was reduced by 13 kg/t, but there was still room for the further tapping the potentialities and reducing the consumption.
