Analysis of Element Distribution Character in Thickness Direction of Continuously Cast Continuously Rolling 10CrNiCu Steel Plate

  • 摘要: 采用激光原位分析技术,研究了连铸连轧10CrNiCu钢板中各元素在板厚方向的分布,结果表明:C在钢板下表面含量高,上表面含量低;P、S偏析微区弥散分布;Mn、Ni、Cr、Si基本沿板厚中心对称分布,为中心正偏析,Cu的分布最均匀。元素的偏析度基本与原子半径大小成反比关系,C的偏析度最大,P、S、Si偏析度居中,Mn、Cr、Ni、Cu的偏析度较小。
    Abstract: The element distribution character in thickness direction of continuously cast continuously rolling 10CrNiCu steel plate was studied by laser in situ analysis technology. The results show that the content of C in lower surface is higher than that of upper surface, the segregation micro zone of P and S scatter finely, Mn, Ni, Cr, Si are central positive segregation and distribute symmetrically along the center line of the steel plate, Cu is well-distributed, the relationship between segregation and radius of element atom is inverse proportional, the segregation of C is most significant, the segregation of P, S, Si are medium, the segregation of Mn, Ni, Cr, Cu are minute.
