Abstract (en)
[origin: WO9739844A1] Method for the maintenance of rolls/shells for rolling materials, e.g. light metals/aluminium, and casting of such materials in rolling mills, characterized in that the small ridges which are created on the surface of the roll during operation are removed continuously or periodically with a suitable machining tool being adapted to leave the surface layer of the roll essentially intact. The control of the machining tool may either be an active system which localizes the positions of the ridges, or a passive system which in a chosen way follows the surface.
