Abstract：The ladle life and the number of continuous pouring furnaces is an important economic and technical index to measure the production capacity of the continuous casting machine. By improving the ladle life and the number of continuous pouring furnaces， not only can the production rhythm of the steelmaking process be stabilised， the operation rate of the continuous casting machine be effectively improved and the number of ladle changes be reduced， but also the cost of resistant materials and the temperature of the steel output before the furnace can be reduced and the metal yield can be improved.

Key words：intermediate ladle; number of continuous pouring furnaces; production practice

阳春新钢铁有限责任公司炼钢厂拥有五机五流小方坯连铸机3台，主要生产HRB400E，HRB500E，HPB300，XGL等钢种，普碳钢最高拉速5.7 m/min、工作拉速4.0～4.8 m/min，因中间包寿命普遍不高，导致金属收得率低、能耗高，大大增加了炼钢工序成本和员工劳动强度。（剩余3270字）
