摘　　要：针对某钢厂经VD工艺60 t钢包自开率偏低问题,分析了影响钢包自开的热修作业、水口座砖材质、钢种、钢包温度、钢水镇静时间、钢包盛钢时间等影响因素。由于钢包经过VD精炼盛钢时间长,导致引流砂烧结层厚而钢包自开率低。通过对引流砂材质进行优化改进并进行对比试验,改进后的引流砂经过VD工艺钢包自开率达到99.38%的良好效果。In view of the low self opening rate of 60 t ladle after VD process in a steel plant,the influencing factors such as hot repair operation,nozzle brick material,steel grade,ladle temperature,molten steel holding time and storage time of molten steel in ladle were analyzed.Due to the long storage time of molten steel in ladle after VD refining,the sintering layer of stuffing sand was thick and the self opening rate of ladle was low.Through the optimization and improvement of the material of the stuffing sand and the comparative test,the self opening rate of the ladle of the improved stuffing sand after VD process reached 99.38%.
