摘　　要：研究分析了影响稀土钢连铸板坯纵裂的多种工艺因素 ,包括钢中化学成分、结晶器保护渣、结晶器拔热量、二冷水、拉速和中间包过热度等。据此采取了有效措施 ,彻底消除了稀土钢板坯纵裂。Many factors of formation of longitudinal cracks in continuous cast slabs of rare earth steel have been studied, such as chemical composition, mold powder type, heat transfer in mold, secondary cooling intensity, casting speed and superheat of molten steel in tundish. Some effective measures were accepted to eliminate longitudinal cracks completely.
