Abstract (en)
[origin: US2010000278A1] A strip has a left and a right side. The strip is rolled in a rolling stand. Stresses occurring in the strip at the feed and exit sides are detected by corresponding measuring sensors positioned on the left and right sides of the strip. The detected stresses are fed to a control unit for the rolling stand. The control unit determines a measurement for the transversal positioning of the strip in relation to the rolling stand using the relationship Z=ZLE*ZLA-ZRE-ZRA, where Z is the measurement. ZLE, ZLA, ZRE and ZRA are the individually detected stresses. The control unit determines a correcting variable for correcting the transversal positioning of the strip using the measurement for the transversal positioning and controls the rolling stand according to the correcting variable.
