Abstract (en)
[origin: EP0618020A1] A method for rolling the strip (3;4) in a hot-strip mill (6) having at least two rolling stands (6,7) with horizontally adjustable upper and lower work rolls (10,11) each of which is supported directly or by way of an intermediate roll on a back-up roll (9), or in a reversing stand on which at least two passes are performed, in which the strip is subjected to state control, for which purpose profile-and flatness-determining final control elements act on the strip, makes it possible to meet the requirements relating to the profile accuracy and flatness of the strip despite flexible rolling programs if a target contour for the profile of the strip (3;4) is specified, for the achievement of which two groups of final control elements act successively on the strip, the final control elements (12,13) of the first group being brought into action when the thickness of the strip is above the critical thickness and primarily influencing the contour of the strip in its central area relative to the centre of the strip, while the final control elements (12,13) of the second group are brought into action when the thickness of the strip in the region of the edge is below the critical thickness. <IMAGE>
