摘　　要：分析了某钢厂80t整体浇注钢包包龄的影响因素,通过对比不同的冷修模式和包衬材质,确定了同步冷修模式和高铝矾土质包衬的最优成本方案。通过合理设计包胎外形尺寸、优化钢包浇注料的材质、优化透气砖和座砖结构,同时采用立轴搅拌机改善施工质量等措施,明显提高了同步冷修模式钢包的包龄,并通过全程包壁温度监控,既保证了钢包使用的安全,又能最大限度地提高钢包包龄,平均包龄达到170次左右,有效降低了成本。The factors affecting the ladle life of 80 t integral pouring ladle in a steel plant were analyzed, the optimal cost scheme of synchronous cold repair mode and high alumina soil ladle lining was determined by comparing different cold repair modes and ladle lining materials. The ladle life of synchronous cold repair mode is obviously improved by reasonable design of the overall dimensions of ladle tire, optimization of the material of ladle castable, optimization of the structure of permeable brick and seat brick, and improvement of construction quality by using vertical shaft mixer. Through the whole process of ladle wall temperature monitoring, not only the safety of ladle use is ensured, but also the ladle age is increased to the maximum extent. At present, the average ladle age is up to about 170 times, and the cost is reduced effectively.
