Abstract: If more ladles are put in for turnover，the waiting time for empty ladles will be longer，the energy consumption of steelmaking will increase，and the number of thermal vibration times of ladles will increase. Blindly reducing the turnover of ladle will lead to problems such as converter waiting for ladles and even the interruption of casting machine. Combined with the characteristics of equipment of Shouqin Metal Material Co.，Ltd.，the detailed parameter analysis was carried out based on the principle of furnacecaster matching and with the caster stable continuous casting as the core. The core cycle calculation method was used to calculate the reasonable turnover quantity of ladle and determine the turnover quantity of ladle when different casting machines were used in Shouqin. By strengthening the combination of casting machine casting schedule and ladle turnover plan，clarifying the standard operating time of each process，optimizing the process route，and strengthening ladle management，the number of ladle turnover was reduced from 13.5 to 12.

Key words: steel ladle, continuous caster, furnacecaster matching, ladle turnover plan
