摘　　要：利用转炉干法除尘灰开发出一种适用于转炉冶炼过程造渣的新型复合造渣剂,该新型复合造渣剂能够满足干法除尘稳定运行以及各项转炉冶金性能的要求。采用新型复合造渣剂后转炉氧气消耗降低了2.65 m3/t,转炉终点脱磷率提高3.31%,钢铁料消耗降低0.69 kg/t,吨钢煤气回收平均提高了5m3,吨钢辅料成本降低2.68元。A new composite slagging agent for BOF steelmaking was developed by using dust. The new composite slagging agent could meet the requirements for the stable operation of dry dedusting and metallurgical properties. Through using this new type of composite slagging agent, the oxygen consumption of converter steelmaking was decreased by 2. 65 m3/t, the dephosphorization rate was increased by 3. 31 %, the ferrous charge consumption was reduced by 0. 69 kg/t, the volume of gas recovery was increased by an average of 5 m^3, and the cost of steel materials was reduced by 2. 68 yuan/t.
