摘　　要：分析了半钢炼钢在造渣时遇到的困难和原因,阐述了"留渣+提钒转炉出钢预成渣+石灰石造渣"技术用于转炉半钢炼钢的优越性,可以改善半钢炼钢的造渣效果和终点控制问题,炼钢降低了造渣料成本3.19元/t,减少了转炉造渣料消耗。It is analyzed the difficulty and the reason in slag making in steel making with semisteel,stated the superiority of technique ＂ remaining slag,extracting vanadium converter tapping pre- making slag,limestone making slag＂. That technique can improve the slag- making effect and end control. With it the cost of slag- making materials is reduced by 3. 19 yuans per ton of steel,the slag- making materials consumption low-ered.

关 键 词：半钢炼钢成本 造渣技术 实践
