Abstract

PURPOSE:To produce the dull finishing roll having the life equivalent to that by an electrical discharge machining method and yet has uniform satin patterns and roundness by applying the combination of shot blast method dull finishing and nitriding to the roll using hardened forging steel. CONSTITUTION:The surface of a roll using hardened forging steel material (preferably of chromium content of about 3 to 5wt%) is shot blasted to form a dull finished surface and is then applied with nitriding (preferably ion nitriding method), whereby the worked surface is hardened.
