The invention relates to a method for specifically adjusting the surface structure of rolling stock (3) during cold rolling in skin pass mills. The aim of the invention is to partially transfer the surface structure of the working roll (2) onto the rolling stock (3). To this end, the change of roughness of the rolling stock (3) in the rolling process of a single- or multiple-stand, preferably two-stand skin pass mill is calculated in an optimization calculation in which the tolling parameters are varied according to the mill capacity using a tribological model that mathematically describes the friction conditions in the roll gap (1). The results obtained are then used to readjust at least a part of the rolling parameters used for calculation.
Method for systematically adjusting the surface structure of rolling stock during cold rerolling in temper rolling mills, in which there is a partial transfer of the surface structure of the working rolls (2) to the rolling stock (3), characterized by the fact that the change in roughness of the rolling stock (3) in the rolling process of a single-stand or multiple-stand, preferably two-stand, temper rolling mill is calculated with an optimization calculation, in which the rolling parameters are varied according to the available mill capacity, with the use of a tribological model that mathematically describes the friction conditions in the roll gap (1), and the results obtained in this way are used to preset at least some of the rolling parameters used in the calculation.
