Patent ID: 6948346

Claim:
Method for systematically adjusting 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 ), wherein a 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 rolling parameters are varied according to an available mill capacity, with the use of a tribological model that mathematically describes friction conditions in the roll gap ( 1 ), and results obtained in this way are used to preset at least some of the rolling parameters used in the calculation with target values, wherein the calculation of the tribological model is performed in such a way that the rolling stock ( 3 ) has a constant roughness after the last stand at all rolling speeds (v) (calculation of the rolling parameters as a function of the rolling speed v) and the overall degree of temper rolling (sum of the degrees D of temper rolling of the individual stands) is held constant.
