| 摘 要： | 边裂是热轧钢带生产过程中出现的边部缺陷.通过对边裂的统计分析、租轧坯低倍缺陷分析、边裂的三维向显微组织的分析,对其形成原因及机理进行了研究.结果表明:钢坯缺陷使钢的致密性降低,使氧易于渗透并发生氧化,这是热轧带出现边裂的主因；强宽展及不均变形等轧制条件促使粗轧坯内部缺陷的扩展、氧化,这是边裂产生的外因；提出加强钢水中气...

| Abstract: | Edge cracking of hot rolled strips is an edge defect forming during hot rolling.The cause and mechanism of edge cracking of hot rolled strips was studied by analyzing appearance and microstructure of edge cracking defects as well as the defects in rough rolled billet.The results show that the billet defects caused the decrease of compactness,and made oxygen penetrate in and oxidation take place,which is the main reason for the edge cracking of hot rolled strips.Mandatory broadside rolling and uneven deforma... |
