摘要: 铸坯出现裂纹轻者需要对铸坯进行精整，严重的会出现漏钢事故或产生废品。因此，裂纹的产生既影响到了连铸机的生产效率，又影响到了产品的质量，增加了成本。而铸坯中的内部裂纹若在后续的轧制过程中没有消除或减轻，将会对产品的质量和使用寿命产生很大的影响。本文针对连铸板坯典型内部裂纹(中间裂纹、三角区裂纹、中心裂纹)的特征及产生机理进行了系统探讨，同时对轧制过程内部裂纹的愈合行为进行了分析。
Abstract: It is necessary to finish the billet if the cracks are light. If the cracks are serious, there will be steel leakage accidents or waste products. Therefore, the generation of cracks not only affects the pro-duction efficiency of continuous casting machine, but also affects the quality of products and in-creases the cost. However, if the internal cracks in the billet are not eliminated or alleviated in the subsequent rolling process, the quality and service life of the product will be greatly affected. In this paper, the characteristics and mechanism of typical internal cracks (intermediate cracks, triangular cracks and central cracks) in continuous casting slab are systematically discussed, and the healing behavior of internal cracks in rolling process is analyzed.
