    摘要
  • 摘要: 通過現場取樣進行電鏡觀察檢測，研究了管線鋼精煉過程中鋼中大尺寸CaO和CaS復合夾雜物形貌、尺寸和成分，并結合鋼液中Ca-O和Ca-S平衡曲線、CaO和CaS熱力學分析，對其形成機理和形成原因進行了研究.實驗結果表明：夾雜物可能是由于鈣處理時喂入了過量硅鈣線造成的.

     

    Abstract: The morphology,size,and composition of inclusions were studied by scanning electron microscopy(SEM) in pipeline steel during refining process. The Ca-O equilibrium curve,Ca-S equilibrium curve,and the stability diagrams of inclusions(CaO and CaS) were discussed to explain the formation mechanism of CaO and CaS complex inclusions. The results show that the excessive addition of Ca-Si wireis the reason causing the formation of CaO and CaS complex inclusions.
