Abstract Some adjustment of cold rolling technology was done to remove fin defect of cold rolled strip, but it couldn’t remove the defect completely. At the same time bright brand was found on surface of hot strip, and it was found that the position of bright band on hot rolled strip might be corresponded to the position of fin defect. It was proved that the bright band was local high point of hot strip formed by nonuniform wear of the roller. Through optimizing roller shape of hot rolling mill the bright brand on hot rolled strip and fin defect of cold rolled strip were eliminated.

Key words： fin defect of cold rolled strip bright brand of hot rolled strip roller shape medium thin slab continuous casting and rolling
