Abstract: 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.
