A method and apparatus for measuring and controlling the flatness and / or the degree of a stainless steel strip or a stainless steel foil during the cold rolling in a cluster mill, in particular in a 20 - rollers - sendizimir - rolling mill

摘要

A method and a device for the measurement and control of the flatness and / or the degree of a stainless steel strip (1) during the cold rolling in a cluster mill (2) with at least one of several control elements (3) comprising a control circuit (4) ensures a more accurate measurement and regulation in that a departures from flatness (10) by comparison of a voltage kon vector (8) with a predetermined reference curve (9) is determined, then the course of the flat unit error (10) over the width of the strip (7) in an analysis module (11) mathematically approximated in proportional tension vectors (8), and the broken down by real numerical values given plan and beauty - error components in (c1.. cx) respectively associated control modules (12a; 12b) for actuating the respective adjustment member (3) are supplied to.
