| Abstract: | In order to increase the converter production capability, with optimization of converter oxygen supply schedule- oxygen lance level and charging mode, basic lime and dolomite amount according to different Si content in metal and bottom blowing process, and control tapping temperature, the converter end point first percentage of hits increases from 89. 5% to 95. 45% to decrease times of reblow； the average end [ N] decreases to 35 x 10-6 ； and by virtuous turnover of ladle and reasonable control of tap time, the temperature of liquid is ≥1 560℃ as ladle at refining station. |
| Keywords: | Top and Bottom Combined Blown Converter Blowing Steelmaking Process Optimization |
