The working roller has a cylindrical center portion defining a central axis, the center portion having an outer surface defining a lamination surface; and first and second frustoconical portions extending from first and second ends of the center portion respectively. When the central axis is straight, an angle between the outer surface of the center portion and an outer surface of each of the first and second frustoconical portions is less than 0.05 degrees. A width of the center portion is greater than a width of each of the first and second frustoconical portions. The width of the center portion is less than a sum of the widths of the first and second portions. A rolling mill having two such working rollers is also disclosed.
