一种转炉高强度复吹双渣工艺脱磷期全生料造渣方法，属于转炉冶炼技术领域。转炉采用留渣冶炼，脱磷期氧枪供氧强度3 .0～4 .5m^3/min·t，底吹气体强度0.15～0.30m³/min·t，氧枪点火成功后加入石灰石13～17kg/t钢，生白云石12～15kg/t钢，石灰石和生白云石各分2～5次在2～3min内加完。吹氧200～500s提枪，可根据实际吹炼状况加入0～25kg/t钢的铁矿石或返矿或烧结矿调节倒炉温度，倒炉温度控制在1320～1390℃，倒炉脱磷率可达到50％～70％之间。优点在于，加料方法简单易操作且脱磷率稳定，全生料造渣成本低廉，降温效果好，同时采用矿料调温减少了矿石前期工序处理，具有良好的经济效益。

A slag-making method for whole raw material during dephosphorization period of converter high strength combined blowing and double slag process, which belongs to the field of converter smelting technology.The converter adopts slag retention smelting, oxygen supply intensity of oxygen lance during dephosphorization is 3.0~4.5m³/min·t, bottom blowing gas intensity is 0.15~0.30m³/min·t, limestone 13~17kg/t steel and dolomite 12~15kg/t steel are added after oxygen lance ignition, limestone and dolomite are added in 2~5 times in 2~3min.When blowing oxygen for 200~500s and lifting the gun, the pouring temperature can be adjusted by adding iron ore or return ore or sinter of 0~25kg /t steel according to the actual blowing condition. The pouring temperature is controlled at 1320~1390℃, and the dephosphorization rate of pouring furnace can reach 50%~70%.The advantages are that the feeding method is simple and easy to operate, the dephosphorization rate is stable, the cost of whole raw material slagging is low, and the cooling effect is good. At the same time, the ore pre-processing is reduced by using ore temperature regulation, which has good economic benefits.
