摘要
为实现效益最大化,马鞍山钢铁股份有限公司第一钢轧总厂120 t转炉采用高铁水比冶炼低碳低磷系列钢种时,应用烟气分析动态控制和矿石加生烧温控技术,解决因热量富余而产生的成分温度波动大、喷溅机率高、终点命中率低等问题,实现出钢钢液中w(P)<0.015%,终点C-T双命中率达91.2%,石灰等渣料消耗从87.1 kg/t降低到79.5 kg/t以下,吹损率从10.3%降低到8.7%以下,成本及消耗降低的良好效果。
To realize the benefit maximization the offgas analysis and dynamic control technology as well as temperature control technology by addition of burnt dolomite in the ore are applied to solve the problem of severe temperature and composition fluctuation, high probability of splashing and low end point hit ratio due to surplus heat and realize the targets of w(P)〈0.015 % in tapping, 91.2 % of dual hit ratio of end point C-T, reduction of the slag materials such as lime from 87.1 kg/t to 79.5 kg/t and decrease of the metal loss from 10.3 %to below 8.7 %in refining the low carbon and low phosphorous steel series with high hot metal ratio in the 120 t BOF converter in No.1 Steel Making and Rolling Mill in Maanshan Iron &Steel Co., Ltd and very satisfactory results have been achieved in reduction of production cost and material consumption.
