Abstract：The awareness, preparation, fast changing conditions, time and operation points of the tundish quick change in the steel plant of Fujian Sanan Iron and Steel Co., Ltd. were described. The practice showed that the rational utilization of the tundish quick change process could improve the operating rate, the yield of molten steel and reduce the shutdown accident caused by the process, equipment and human factors. The number of start and stop was reduced and the effect of the operation of cast starting and teeming stop on the quality of the slab was decreased. At the same time, the equipment cycle management and state management level could be improved, the maintenance cost could be reduced, the utilization rate of the equipment maintenance personnel working hours could be increased, and the maintenance rate could be increased from 75.9% before the quick change to 99.24%.
