| 摘 要： | 通过现场取样进行电镜观察检测，研究了管线钢精炼过程中钢中大尺寸CaO和CaS复合夹杂物形貌、尺寸和成分，并结合钢液中Ca-O和Ca-S平衡曲线、CaO和CaS热力学分析，对其形成机理和形成原因进行了研究.实验结果表明：夹杂物可能是由于钙处理时喂入了过量硅钙线造成的. |

| 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. |
