摘　　要：通过脱磷热力学计算与物料平衡计算得出转炉脱磷所需总渣量,并结合转炉氧化脱磷三要素,调整少渣冶炼工艺参数及措施,实施少渣冶炼。工业试验表明,在保证成品钢种磷含量稳定的前提下,冶炼总渣量降低了11.46 kg/t,氧气消耗降低了417 m3/炉,煤气回收总量提高了57 m3/炉,钢铁料消耗降低2.08 kg/t。Through thermodynamic calculation and material balance, the total amount of slag that needed for BOF dephosphorization was obtained. Meanwhile, combined with three key elements of BOF dephosphorization, the parameters and measures of BOF steelmaking with less slag were adjusted. The industrial test showed that the total amount of slag was reduced by 11.46 kg/t, oxygen consumption was decreased by 417 m^3 per heat, the volume of gas recovery was increased by 57 m^3 per heat, and the ferrous charge consumption was declined by 2. 08 kg/t on condition that the phosphorus content of steel was kept stable.
