通过对热轧中板裂纹形貌的检验．确定了M形裂纹成闲。经过对钢种特性的分析和现场跟踪．查找铸坏产生裂纹的原因，并采取相应措施，消除了Q345系钢种中板的M形裂纹缺陷。
The cause for the M-type sliver were identified by inspecting the appearance of cracks. By analyzing char- acteristics of the steel grade and tracking the production on site, tile causes for the cracks of the slab were found out. And also corresponding measures were taken to eliminate the M-type sliver of Q345 steel.
