かじりが防止される。(Problem to be solved by the invention) In rolling, steel plates are manufactured by transferring the uneven pattern on the roll surface onto the steel plate surface, but the press formability of the steel plate depends on the mechanical properties such as the r value and elongation of the steel plate. In addition, steel plate surface roughness and lubricating oil have a large influence. Generally, the lubricating oil accumulated on the four parts of the concavo-convex pattern is evenly supplied to the convex parts, thereby improving lubrication conditions and improving press formability, that is, preventing mold galling.

The surface of a rolling work roll is coated with a photosensitive resist agent or film, and the resist layer is cured by intermittently irradiating high-density energy while rotating the roll. The uncured portion of the roll is cleaned to form one or more motifs on the roll surface, and the roll is anisotropically etched with a chemical etching agent to form etch bits on the roll base material to form the desired motif. 1. A method for forming an uneven pattern on the surface of a dull roll for rolling a steel plate, the method comprising: obtaining a resist hardening layer, and then cleaning and peeling off a hardened resist layer. 2. By forming a hard metal plating film on the surface of a rolling work roll, coating the surface of the plating film with a photosensitive resist agent or film, and intermittently irradiating high-density energy while rotating the roll. , the resist layer is cured, the uncured portion of the roll is cleaned to form one or more motifs on the roll surface, the roll is anisotropically etched with a chemical etching agent, and the plated layer is etched with etch bits. 2. The method according to claim 1, wherein the desired motif is obtained. 3. According to claim 1 or 2, the roll surface is coated with a different material after anisotropic etching is performed using a chemical corrosive agent to form an etch bit to obtain a desired motif, and then the hardened resist film layer is peeled off. the method of.
