摘要
随着攀钢集团西昌钢钒公司高级别钢种的不断开发,转炉生产难度加大,为了满足低磷品种钢的要求,西昌钢钒通过试验总结出一套适合于半钢冶炼低磷、高品质钢种的工艺。通过优化转炉冶炼氧枪工艺,选择合理复吹制度及造渣制度,控制冶炼终点温度在1 620℃左右,结果终点磷含量由原先0.013%稳定降低到0.006%,满足了生产高品质钢对脱磷的要求,此工艺的试验成功为后期高端品种开发打下了坚实基础。
In order to meet the strict requirements of low- phosphorus steels, a suitable process was invented by Xichang Vanadium ＆ Steel to smelt low-phosphorus high quality steels with semi-steel. By optimizing the oxygen lance of converter smelting process, selecting reasonable combined blowing and slag making schemes, and controlling end-point smelting temperature at about 1 620 ℃, the end-point phos-phorus content was stably reduced from 0.013% to 0. 006%, satisfying the requirements of high quality steels on dephosphorization.
