Abstract At present steel workshops exists the rhythm of production between converter and continuous caster does not match phenomenon，which need to saving ladle production to ensure the caster casting，therefore the scientific-reasonable saving ladle’s control model of steel making plant could achieve energy saving significance．Based on the C steel workshop’s steel ladles as the research object，this article analyzes its operation mode and time，converter and caster matching model．Through analyzing the relationship between the time of saving ladle and the number of continuous caster’s heats ，the operating time control model of steel ladle’s saving ladle is constructed，which could calculates the reasonable value of saving ladle’s time，heavy ladle’s operation time and steel ladle’s turnover cycle．Through applying Gantt chart to analysis and study the turnover rule of saving ladle，the turnover number control model of steel ladle is constructed also．Satisfactory effects were obtained after applying the control model in production：saving number and turnover number were reduced，turnover ratio was increased and temperature drop was reduced．
