Abstract

Provided is a method for manufacturing a roll for reducing, wherein the occurrence of fin flaws and edge flaws can be suppressed. A roll for reducing used in a three-roll reducing mill is prepared. Next, while the roll for reducing is being rotated about a roll axis, a ridge part (52) formed in an adjacent section between a caliber part and a flange part is cut to round the ridge part (52). In the step for rounding the ridge part (52), in a ridge part region (RA52) within a range of 3.0 mm in a roll axis direction with the top of the ridge part (52) as the center, the average of curvature radii measured at 0.5 mm pitch is set to 2.5-3.0 mm, and the difference between the maximum value and the small value of the curvature radii is set to 1.0 mm or less.
