Abstract: A method for producing metal strip in a rolling mill, so that as a result of a more accurate manufacturing of metal strips in the future, a more precise forecasting of the profile contour of the metal strip can be obtained over the width of the metal strip, as well as a more precise setting of the profile actuator of the rolling mill. A forecast value is calculated for the profile contour within the context of the simulation of the rolling process before the rolling of the metal strip. In contrast to that, the calculation in the simulation is not conducted prior to the rolling, but instead it is obtained by a post-calculation after the rolling of the metal strip has been carried out.

Abstract: A method ascertains control variables for active profile and flatness control elements for at least one rolling stand for hot rolling metal strip with a plurality of i=1 . . . I successive passes and for ascertaining profile and center flatness values for the hot-rolled metal strip. The occurrence of fluctuations in the center flatness of the metal strip after the individual passes and the resulting disadvantages for the rolling stability and the product quality are prevented. The method provides that, also for the target center flatness of the metal strip after a predetermined pass k with i=1 . . .
