摘　　要：从热轧原板材料缺陷性能、冷轧工艺等方面分析了冷轧板边裂产生的原因。认为冷轧轧机负荷分配和机架间张力控制不当是边裂产生的主要原因,热轧板边部混晶和硬度波动对其边裂有一定影响。优化冷轧工艺,有效控制热轧板组织均匀性,是解决边裂的主要措施。It is analyzed the reason for edge crack on cold -rolling sheet from aspects： defects in properties of raw hot - rolling plate material and cold - rolling process. It is considered the unsuitable load distribution be- tween cold - rolling mills and tension control between stands are the main reason, and the edge mixed crystal and hardness fluctuation of hot - rolling plate have also some effect. To optimize cold - rolling process and effectively control the structure homogenization of hot- rolling plate are the main measures.
