Removal of copper from iron scraps by solidification refining

采用凝固精炼法去除铜，研究了Fe-C-Cu体系中Fe的脱除工艺。采用Fe-C-C熔体单向凝固方法，研究了凝固过程中Cu的偏析。此外，还发现Cu的偏析程度不依赖于体系中的初始Cu含量。这些发现证实了通过凝固精炼去除Cu的潜力。

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.
