Abstract
The industrial practice of pulverized coal injection with combustion-supporting agent in the No.5 blast furnace of Ansteel was carried out, and the goal was to get the effect of Mn series combustion-supporting agent on pulverized coal injection. The dailly production of hot metal with 0.4%-0.6% combustion agent grew up 435.6t compared with the index without combustion agent, coke rate decreased 10.3kg/t hot metal, the coal injection improved 8.1kg/t hot metal, the CO2 proportion in gas decreased 0.69%, and the average combustion efficiency reached 4593% which was 6.06% higher than traditional operation.
