Abstract

A method for producing a metal sheet with raised lines uses a rolling mill including a roll stand and produces a metal sheet including, on each of an upper surface and a lower surface, a plurality of raised lines extending in a rolling direction. The method includes a preparing step, an incorporating step, and a forming step. In the preparing step, grooved rolls are prepared, each of the grooved rolls including a plurality of grooves in an outer peripheral surface. In the incorporating step, the grooved rolls are incorporated in the roll stand as an upper roll and a lower roll, respectively. In the forming step, a workpiece is rolled by the rolling mill and is formed into a metal sheet with raised lines formed corresponding to the respective grooves of the grooved rolls.
