文章对影响钢包钢水自动开浇率的各种因素进行了分析,并结合太钢二炼钢的实际情况(80t碳钢包、180t碳钢包、75t不锈钢钢包及180t不锈钢钢包),通过采取改善引流砂材质、改进灌砂方式、对引流砂加热、强化座砖和水口清洗、提高钢包上线温度、对座砖和滑板预热等措施,使太钢二炼钢的碳钢包自动开浇率达到了99.8%以上,不锈钢钢包自动开浇率达到99.5%以上。
Based on the analysis of various factors that affect the automatic pouring rate of ladle molten steel and by combining the actual situation of the second Taiyuan Iron and Steel (80t carbon steel bag, 180t carbon steel bag, 75t stainless steel ladle and 180t stainless steel ladle) Drainage sand material, improved sand filling method, the drainage sand heating, strengthening the brick and nozzle cleaning to improve the temperature on the ladle on the block brick and skateboard preheating and other measures so that the second steelmaking Taigang carbon ladle automatic casting rate reached More than 99.8%, stainless steel ladle automatic casting rate of 99.5% or more.
