A method for improving the running-out of a metal rolled strip (1), the rolled trailing strip end (1a) of which exits out of a respectively last roll stand (2) of a multistand rolling mill (3) at a rolling speed, wherein during rolling between two consecutive roll stands (F1, F2, F3 . . . Fn) the strip tension (a) is adjusted to stabilize the strip position, provides that shortly before the rolled trailing strip end (1a) exits the developing rolling force differences are measured separately for each roll stand (F1, F2, F3 . . . Fn), that from this the pivot value (16) and the pivot direction are derived for forming a corrective value for the adjustment of the rolls (10, 11) and that the adjustment is corrected.
A method for improving the running-out of a metal rolled strip whose trailing strip end exits the last roll stand of a multistand rolling mill at rolling speed, with strip tension being adjusted during rolling between two consecutive roll stands to stabilize strip position, wherein shortly before the rolled trailing strip end leaves a stand the difference in rolling forces developing between the drive side and the service side are measured separately for each roll stand, that from this a pivot value and a pivot direction of the rolling force difference is derived so as to form a corrective value for positioning of the rolls and the position is corrected.
A rolling mill for the hot rolling of a metal rolled strip, particularly a thin steel strip, with a plurality of roll stands operating on a rolling line, the working rolls and support rolls of which are driven on the drive side so as to maintain the strip tension for stabilization of the passage and for a high rolling speed, and with measuring devices being provided on the drive side and the service side for measuring the rolling force wherein the rolling forces on the drive side and on the service side can be determined as a rolling force difference by means of force-measuring sensors shortly before the metal trailing strip end exits, that an evaluation unit for the rolling force difference of the metal trailing strip end and a computer for computing a pivot value for the adjustment of the rolls during passage of the metal trailing strip end are provided.
A method of operating a rolling system having at least three roll stands that grip a metal strip and advance it in a feed direction with each stand having a service side and a drive side spaced transversely apart relative to the direction, the method comprising the steps of:
