3003铝合金冷轧板带孔洞缺陷分析及预防措施

摘要

采用扫描电镜和能谱分析手段对铝合金冷轧板带的孔洞缺陷进行分析，指出扁锭夹杂、异物压入和轧辊异常是冷轧板带孔洞缺陷产生的主要原因；提出预防孔洞缺陷产生的措施。%The paper analyzed hole defect of cold rol ed aluminum strip using SEM and EDS;it pointed out that the hole defect was generated mainly by slab inclusion,pressed-in foreign matter and abnormal rol ,and it put forward measures for preventing holes from being formed.
