摘　　要：针对55冷轧钢带生产过程中产生边裂缺陷问题,借助金相和电镜等理化检测手段对成因逐一进行了筛查。确定了连铸坯棱角裂纹是引起冷轧钢带边缘开裂的原因,并提出了生产工艺优化措施。In viewof the edge crack of 55 cold rolled steel strip,it is determined that the defect is caused by the corner crack of continuous casting billet by means of metallograph and TEM. And the optimization measures for production process are put forward.
