Research Abstract

Removal of Cu by solidification refining with the segregation of Cu in.-Fe in Fe-C-Cu system was investigated as a removal technology for tramp-elements from iron-scraps. The segregation of Cu during solidification was clarified with the one-directional solidification method of Fe-C-C melt. In addition, it was found out that the degree of segregation of Cu does not depends on the initial Cu content in the system. These findings confirm the potential of the removal of Cu by solidification refining.
