Abstract: 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 2.65m3/t, the dephosphorization rate was increased by 3.31%, the ferrous charge consumption was reduced by 0.69kg/t, the volume of gas recovery was increased by an average of 5m3, and the cost of steel materials was reduced by 2.68 yuan per ton.
