摘　　要：介绍了目前转炉出钢前期挡渣采用的方法,针对鞍钢股份有限公司鲅鱼圈钢铁分公司转炉前期挡渣存在的问题,对挡渣时机及挡渣塞材质进行了优化,转炉前期挡渣成功率达到96%以上,脱氧合金成本和成分合金成本共降低29.4万元/月,避免因磷高产生废品引起的损失7.8万元/月。The current method for slag stopping prior to tapping from convertor is described.For the problems occurred in slag dam system in Bayuquan Iron Steel Company of Angang Steel Co., Ltd., the moment for slag stopping and the material for a floating plug are optimized. So prior to tapping from convertor the success rate for slag stopping is over 96% and the cost of deoxidation alloy and alloy ingredients is reduced by 294 thousand yuan RMB per month and further more avoiding the loss of 78 thousand yuan RMB per month due to the disqualified molten steel caused by high content of phosphorus is achieved.
