摘　　要：首都钢铁集团公司迁安钢铁有限责任公司炼钢厂经过设备改造和技术革新,转炉下渣控制水平取得了一定的进步。对于吹炼汽车板等低碳钢种,钢包内渣厚能够控制在平均33.7mm,下渣量控制在平均4.8kg/t。此外,转炉终渣中T.Fe含量的升高和未使用下渣检测设备等都有可能导致下渣量增大。Technological level for slag amount control from converter to ladle have been improved to some extent by revamp of the equipments and innovation of technologies in Hebei Shougang Qian＇an Iron ＆ Steel Co. , Ltd. For those low carbon steel grades used in automobile sheets up to date the thickness of the slag layer in the ladle can be controlled within an average of 33. 7 mm and the slag amount to ladle from converter be controlled in a mean value of 4. 8 kg/t. Besides, a rise of T. Fe content in the end point converter slag and absence of usage of slag detective and measurement devices may cause an increase of slag amount to the ladle.
