Abstract (en)
[origin: WO2009016086A1] The invention relates to a method and a control device for performing the method for adjusting a state (S1, S2, S3) of a rolling stock (G, GX), particularly a near-net strip, defined at least by an out-of-parallel condition and/or a curvature of the rolling stock (G, GX), the rolling stock (G, GX) being transitioned from an initial state (S1) into an intermediate state (S2) by rolling by means of a roll stand (1), particularly a leader stand, and by impressing a stress (s) onto the rolling stock (G, GX) by means of additional processing means (7, 8), and the rolling stock (G) being transitioned from the intermediate state (S2) thereof into a final state (S3) by means of at least one processing aggregate (A1, A2, A3,..., AN). By determining whether rolling stock (G, GX) should be fed into the at least one processing aggregate (A1, A2, A3,..., AN), the intermediate state of said rolling stock requiring a non-zero out-of-parallel condition and/or curvature in order to achieve a predetermined final state (S3'), and the roll stand (1) and/or the processing means (7, 8) being controlled and/or regulated as a function thereof in order to adjust the required intermediate state (S2), a method and a control device can be provided that increase the shape reliability of an ultimately parallel, non-curved rolling stock.
