摘要: 采用化學分析和低倍酸浸實驗方法研究了低碳高硫易切削鋼連鑄坯的C、Si、Mn、P、S的成分偏析特征并分析其形成原因.結果表明,連鑄坯的C、Si、Mn、P、S的偏析度均在0.9~1.1之間,S、P元素存在中心負偏析,低倍酸浸實驗檢測發現連鑄坯存在中心疏松.分析認為,中心疏松是導致中心元素負偏析的主要原因.

Abstract: The characteristics and reasons of C,Si,Mn,P,S composition segregations in low carbon high sulfur free cutting steel were researched by chemical analysis and hot hydrochloric acid. The results show that the segregation degree of elements (C, Si, Mn, P, S) is between 0.9 and 1.1,S and P elements are negative segregation at the billet center region,and the center area of continuous casting billet is porosity. The analyses show that the center porosity is the main reason of element negative segregations at the center area.
