评述了连铸坯内裂纹形成条件的研究方法和结果。得知内裂纹形成的临界应变随应变速率和钢中碳含量增加而减小；随Mn/S的提高而增大。另外，从凝固前沿的确定、显微偏析的影响和实验条件的差异等方面对目前研究中存在的主 要问题进行了探讨。
The method and results of the st udy on formation condition for internal crack in continuous casting slab were re viewed.The results showed that the critical strain for the formation of interna l crack was decreased with the increasing of strain rate and carbon content, and increased with the increasing of Mn/S ratio in the steel.The determination of solidifying front, the influence of micro-segregation, and the difference in ex periment conditions were discussed.
