Zusammenfassung:PROBLEM TO BE SOLVED: To provide a control method of a camber for suppressing the generation of fluting marks which are generated in hot rolling. SOLUTION: In the pass of intermediate rolling by which the thickness of the material to be rolled is made into at least 20-60 mm, rolling conditions are controlled so that the tip part of the material to be rolled becomes an upward camber. Furthermore, the rolling conditions are controlled so that the upward camber becomes 0.5×10-4 to 2.0×10-4 mm-1 in the curvature of camber.
