Patent number: 7854154Abstract: The invention relates to a method for controlling a rolling process, in which a metal strip is rolled flat by use of at least one roller. It is known from the prior art that the relative position of a neutral point represents a measure of the instantaneous stability of a rolling process. However, traditional methods for calculating the position of the neutral point do not accurately represent the actual properties of metal and therefore have only limited usefulness for predicting the stability of a rolling process. In order to allow better control of a rolling process for rolling a metal strip with regard to the actual behavior of the metal strip, the invention proposes a new method for calculating the relative position of the neutral point, in which in particular the flat yield stress ke and the hydrostatic pressure pNH at the neutral point are incorporated.Type: GrantFiled: November 30, 2006Date of Patent: December 21, 2010Assignee: SMS Siemag AktiengesellschaftInventor: Hartmut Pawelski

Patent number: 7854155Abstract: 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.Type: GrantFiled: October 26, 2006Date of Patent: December 21, 2010Assignee: SMS Siemag AktiengesellschaftInventors: Peter Sudau, Olaf Norman Jepsen
