    摘要
  • 摘要: 對薄板坯連鑄連軋生產線（CSP）生產的鋼板出現表面裂紋及邊裂進行了研究,并對CSP鋼板表面裂紋的形成機理及其影響因素進行了分析,提出了防止裂紋的措施.X-射線能譜分析結果表明:在基體與氧化鐵皮間的界面富集有銅等低熔點雜質元素,鋼中殘余元素含量偏高是產生表面裂紋的主要原因.

     

    Abstract: The surface and fringe cracks in thin strips produced by CSP process were studied. The forming mechanism and involved influencing factors were analyzed and then the preventive measures were put forward. The test results show that the main factors causing surface crack on thin strip are the enrichment of impurity elements (Cu,Sn,Sb et al.) in the interface of matrix and iron scale as well as the upper contents of residual elements in steel.
