Abstract (en)
[origin: WO2006002784A1] A method and device for measuring and adjusting the evenness and/or tension of a stainless steel strip (1) during cold rolling in a 4-roll stand (2) provided with at least one control loop (4) comprising several actuators (3), resulting in more precise measurement and adjustment due to the fact that an evenness defect (10) is determined by comparing a tension vector (8) with a predefined reference curve (9), whereupon the characteristic of the evenness defect (10) along the width of the strip is broken down into proportional tension vectors (8) in an analysis building block (11) in a mathematically approximated manner and the evenness defect proportions (C1...Cx) determined by real numerical values are supplied to respectively associated control modules (12a; 12b) for actuation of the respective actuator (3).
