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

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.
