摘　　要：铁水包是高炉-转炉界面的重要组成部分,高炉-转炉界面铁水包周转优化是提升高炉-转炉界面技术运行效果的重要措施。在高炉-转炉界面铁水包周转过程时间统计的基础上,采用分层分析的方法,对比了不同周转时间范围的铁水包在各个环节中用时的差异。结果表明,铁水包周转优化的潜力主要在于缩短出铁等待时间、铁水包受铁时间和脱硫后起吊-兑铁结束时间。此外,钢铁企业高炉-转炉界面技术模式和平面布置对铁水包周转具有重要影响。Hot metal ladle is an key part of the ironmaking-steelmaking interface,and the optimization of hot metal ladle turnover is an important measure to improve the operation effect of interface technology.Based on the time statistics of hot metal ladle turnover process at ironmaking-steelmaking interface,this paper compares the time difference of different ladle turnover time ranges in each stage by using the method of group analysis.The results show that the waiting time of tapping,the charging time of hot metal ladle and the lifting-tapping time after desulfurization are the key factors affecting ladle turnover potential.In addition,the technical mode and layout of ironmaking-steelmaking interface have an important influence on hot metal ladle turnover.
