Skin pass rolls texturing for surface topography formation - using chemical etching engraving and increasing depth of texture by grinding, for improved tribology

摘要

Surface topography or texture is formed on the surface of rolls for skin passes on sheet by transferring a design by a photographic process to the roll surface and the pattern is produced by chemical engraving. The depth of the texture may be increased by grinding. ADVANTAGE - Improves tribology or has decorative effect.
