摘　　要：文章介绍了提高钢包自动开浇率生产实践,通过深入分析影响钢包自动开浇因素,并结合生产实践,提出了多项改进措施。实践表明,通过改进引流砂质量、优化灌砂装置、制定更换水口方案、分钢种严控盛钢时间、防止钢渣回流、缩短钢水静置时间等措施可提高钢包自动开浇率至99.5%以上,达到减少烧氧裸浇坯产生非计划品的目标。In this paper,the production practices on improving automatic casting ratio of ladle are introduced as well as various improvement measures are proposed through deeply analyzing the factors influencing automatic casting of ladle combining with production practices.The practices showed that the automatic casting ratio of ladle could be increased to over 99.5%so that the goal of reducing unplanned products produced by cast billets with burning oxygen is achieved through improving the quality of stuffing sand,optimizing sand filling device,formulating plan of replacing nozzle,strictly controlling time of steel filling according to steel grade,preventing back flow of steel slag and shortening standing time of liquid steel.
