The experiments for cold rolling of stainless steel and carbon steel sheets were made to measure the friction coefficients between rolls and a material, the surface characteristics of rolled sheets such as roughness, gloss and the width spread ratio of sheets. Then, the relations between the friction coefficient and the roll surface profiles, rolled sheet characteristics in cold rolling of steel sheets was discussed. As a result, it has been shown that the friction coefficient for the #800 axial-directionally-polished rolls is smaller than that for the #800 circumferential-directionally-polished rolls , and that the friction coefficient in cold rolling decreases with increase in the ratio of flat area on rolled sheet surface.
