摘　　要：针对热轧板形不好导致冷轧带钢起筋问题,从热轧工序分析原因,得出凸度小楔形大、轧辊磨损不均匀等问题是导致起筋的重要原因,并对热轧的辊形配置、窜辊模型、工艺制度等进行优化。优化后热轧带钢断面形状有很大的改善,带钢板形质量明显提高,带钢在冷轧中出现起筋缺陷的比例明显下降。Aim at the problem of bright band on cold rolling strips which are caused by bad strip shape in hot strip,the reasons are analyzed from the hot rolling process,and study out that there are some reasons lead to bright band such as： strip with small crown and big wedge,uneven wear of rollers. Roll contour,roll shifting model,rolling system are optimized. Section form of hot strip is greatly improved,and quality of strip is increased. The defect ratio of bright band decrease obviously in cold rolled strip.
