摘要
冷轧板表面常常出现线状缺陷。根据3种典型线状缺陷的分布规律、宏观和微观形貌,确认线状缺陷的形成是卷渣、气孔及粗轧过程中板坯边部过度冷却所致的。根据缺陷的形成原因提出了相应的预防措施。
Cold-rolled sheet exhibited often linear defects on surface.From distribution,macrograph and micrograph of the three types of typical defects it has been confirmed that the formation of linear defects was traced to slag entrapment,gas hole,and excessive cooling of the slab edges during rough rolling.The corresponding precautions were put forward according to the cause for formation of the defects.
