Abstract (en)

[origin: WO2013160166A1] A metal strip (1) is roughed in a roughing mill (2), then cooled in a cooling device (3) and finally finish-rolled in a finishing train (8) with multiple rolling stands (9). At the latest when the metal strip (1) runs into the cooling device (3), initial values of a first property of the metal strip (1) are recorded in a spatially resolved form in the direction of the width of the strip and are fed to a rolling model (20). By means of the rolling model (20), expected values of a second property of the metal strip (1) are determined for a location that lies at or behind the first rolling stand (9) of the finishing train (8), in a spatially resolved form in the direction of the width of the strip. The expected values depend on the respective initial values and on the respective activation values (S) of the cooling device (3). The activation values (S) of the cooling device (3) are determined by means of the rolling model (20) in a spatially resolved form in the direction of the width of the strip in such a way that the expected values are made to approximate desired values of the second property in a spatially resolved form in the direction of the width of the strip. The cooling device (3) is activated in a way corresponding to the determined activation values (S).
