The device for casting thin metal products comprises one or two rolls (1) driven in rotation and having cooled walls, and side walls (3) defining a casting space (4). The surface of each roll is divided into at least three circumferential zones, at least one (5) of said zones having a roughness (Rz) greater than the roughness of the other zones (6). This device permits carrying out the process according to the invention in which solely certain longitudinal zones of the skins of cast metal solidified on contact with the cooled walls of the rolls are preferentially driven along.
