CHARACTERISTICS OF ROLLING LOAD, STRIP SHAPE AND STRIP SURFACE IN COLD-ROLLING OF STAINLESS-STEEL FOIL

A demand of stainless steel foil has been recently increasing in electronic apparatuses, electric cells and construction materials. Main subjects in cold rolling of stainless steel foil are strip shap like flatness and fine wrinkles, and surface conditions of rolled strip like gloss and roughness. This paper shows the characteristics of rolling, strip shape and strip surface in cold rolling of stainless steel foil which were obtained by experiments of cold rolling in a twelve-high cluster mill. Main results are as follows. Controllability of strip shape increases more by using doubled-tapered intermediate rolls than by using single-tapered ones. Surface gloss of rolled strip increases with the decrease of surface roughness of work rolls and rolling speed, and with the increase of reduction in thickness.
