分析了带钢冷轧过程中出现的边部“鼓包”缺陷以及对应的测量统计数据,认为热轧带钢局部高点是导致缺陷的主要原因,此外热轧板形凸度、楔形和轧制公里数对缺陷产生也有一定影响。从组织和轧制应力方面分析了带钢局部高点产生的原因,通过改进生产工艺使“鼓包”缺陷明显减少。

The analysis of the edge “drum ” defects and the corresponding measurement statistics in the strip cold rolling process is that the local high point of the hot strip is the main cause of the defect. In addition, the hot rolled plate crown, wedge and Rolling kilometers on the defect also have a certain impact. From the aspects of organization and rolling stress, the causes of the local high point of strip are analyzed, and the defect of “drum package” is obviously reduced by improving the production technology.
