摘　　要：通过对唐钢薄板坯连铸中碳钢SS400纵裂产生原因进行分析,提出了优化保护渣性能、结晶器水量和铜板厚度相匹配等纵裂控制措施。通过采取这些技术措施,使薄板坯纵裂缺陷得到了有效控制。Causes of longitudinal cracking of medium carbon steel SS400 thin slab at No. 1 Steelmaking and Rolling Plant of TISCO were analyzed. Countermeasures such as the optimization of mold powder properties, matching mold water flow rate with the mold copper plate thickness, were put forward. Effective control has been realized through these measures, so the longitudinal cracking on SS400 thin slab was reduced remarkably.
