摘要
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。
Bulging defects at the edge of strip steel forming during cold rolling process and corresponding measuring data are analyzed. It is concluded that local high spots at hot roiled strip steel are the major causes of the defects. In addition, convexity and wedge Of the hot rolled plates and rolling length have certain influence on the formation of defects. Causes of local high spots are analyzed in the aspects of mi crostructure and roiling stress, and finally the bulging defects are noticeably reduced through process im provement.
