摘　　要：为探索助燃剂对高炉喷吹煤粉的影响,进行了鞍钢新5号高炉添加锰系氧化物煤粉助燃剂的工业试验,获得了高炉喷吹煤粉中添加助燃剂下高炉运行指标。结果表明:在添加0.4%～0.6%的助燃剂情况下,平均日产量同未添加助燃剂相比增加435.60t,焦比降低10.30kg/t,喷煤比增加8.10kg/t,高炉煤气中CO2的体积分数下降0.69%,煤粉平均燃烧率为45.93%,提高了6.06%。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 435.6 t compared with the index without combustion agent,coke rate decreased 10.3 kg/t hot metal,the coal injection improved 8.1 kg/t hot metal,the CO2 proportion in gas decreased 0.69%,and the average combustion efficiency reached 45.93% which was 6.06% higher than traditional operation.
