METHOD AND DEVICE FOR MANUFACTURING COLD ROLLED METAL SHEETS OR STRIPS, AND METAL SHEETS OR STRIPS OBTAINED

摘要

Method of producing metal sheets or strips by rolling a metal sheet or strip through cold rolling mills, characterized in that at least two work rolls (2) are textured according to a surface pattern consisting in a regular deterministic bidimensional pattern in the form of unit cells of spots, said spot being obtained through an electron beam irradiation (12) and in that the wavelengths in the longitudinal direction [ lambda L] of the rolls and in the transverse direction [ lambda L] of the rolls are less than 1.5 mm.
