| 摘 要： | 采用扫描电镜对冷轧带钢表面鼓泡处的横、纵断面,鼓泡的破裂面以及鼓泡处拉断表面的形貌进行了观察,并对微区成分作了分析.鼓泡主要是在钢坯皮下由保护渣形成了层状夹杂,导致冷轧原料板出现分层,从而在轧制过程中心部、表面的塑性变形不一致而形成.

| Abstract: | In this paper, the microstructure and composition of surface bubbly defects in cold rolled strip in cross and vertical section were studied by SEM and EDAX. The resuits showed that the bubbly defects were caused by banded inclusion lied in steel slab from mould powder and plastic deformation were not consistent from center to the surface during rolling. |
