Abstract (en)

[origin: EP0075322A2] The method uses cold rolling, which is finished off with a skin pass, during which the surface roughness of the thin sheet is produced by means of skin-pass rolls roughened by a fine-grained inorganic blast medium. The skin-pass rolls used for this purpose have a ground surface blasted by a blast medium which is of a hardness - according to the Mohs' scale - of about 9 and above. <IMAGE>
