摘　　要：结合理论研究和生产实践从钢水成分、钢水过热度,结晶器锥度、结晶器保护渣等方面分析了薄板坯连铸机生产集装箱钢纵裂漏钢和粘连漏钢原因,并且采用了一系列控制措施,如钢中碳含量、硫含量、钢水过热度、结晶器的传热控制、二冷区的弱冷控制、结晶器流场控制等措施,将薄板坯连铸机生产集装箱钢漏钢率由1.25%降至0.35%。Based on the theoretical research and production practice, the causes of longi- tudinal crack breakout and sticking breakout was discussed from of the composition of molten steel, the degree of superheat, the taper of crystallizer, the casting powder of crystallizer, and more aspects. After some regulatory measure was adopted, such as carbon,sulphur content and superheat control of liquid steel, heat transfer control of crystallizer, weak cold control of the secondary cooling zone, and flow field control of crystallizer, the breakout rate of container steel produced by the thin slab continuous casting process has been reduced from 1.25 % to 0.35 %.
