Abstract (en)
[origin: WO2017140605A1] The invention relates to a planishing roll having a surface structure, in particular for producing flat products from a metallic material, in particular from a steel material. In order to devise an improved planishing roll having a surface structure, the surface structure according to the invention has a material ratio of 2% at a depth of 0.2 µm to 9 µm, preferably at a depth of 0.8 µm to 5.5 µm, the depth is measured, starting from a zero line, in the direction of an axis of rotation of the planishing roll, the zero line runs parallel to the axis of rotation of the planishing roll and, starting from the surface of the planishing roll, the zero line is displaced in the direction of the axis of rotation of the planishing roll until the material ratio of the planishing roll is 0.1%. The invention further relates to a method for planishing a flat product made of a metallic material, in particular from a steel material, by using said planishing roll, and to a flat product produced by said method.
