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 . . . <k< . . . I and for the target center flatness after the subsequent passes, pass-specific interval ranges are also specified in each case, and in that the successive calculation of the control variables and profile values is then carried out taking into account such additional specifications as well.

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 for drying a strip (3) or sheet metal that runs through a rolling mill is characterized in that the strip (3) or the sheet metal is cooled to a lower temperature in a cooling section by means of a coolant, in particular a cooling liquid, down-stream of a hot strip mill (1) or, in case of sheet metal, after passing through at least one roll stand (2), and in that the coolant, in particular the cooling liquid, and subsequently the moisture remaining on the strip (3) or the sheet metal is removed from the strip (3) or sheet metal by means of a drying apparatus (10).

Abstract: The invention relates to a method for rolling strips in the roll stand of a rolling mill, wherein said roll stand consists of two axially displaceable working rollers which are provided with a CVC-grinding or a similar contour and whose curved profile is expressed in a third or higher-order polynom and, simultaneously with simple handling of working rollers with large possibilities of adjusting the profile and flatness, the aim of said invention is to homogenize the working rollers wear.

Abstract: The invention relates to a method for providing at least one work roll (1, 2) for rolling strip-shaped rolling stock (3), wherein the work roll (1, 2) is provided to interact with a second roll (4, 5), particularly with an intermediate or backup roller and be supported by said second roll, wherein the second roll (4, 5) has a background area (6) in the axial end regions thereof.
