a method and apparatus for multi-stage rolling stand, the measurement control one or any of its strip stress and flatness of special steel foil or special steel strip cold rolling at 20 roll feed rolling mechanism especially

摘要

[Challenge] And achieves the adjustment conditions that have been changed in the adjustment member respectively, based on the flatness error is analyzed and measured accurately, so obtain a higher flatness of the final product whereby the rolling speed can be increased. [MEANS FOR SOLVING PROBLEMS] It includes a control circuit of one (4) at least include the adjustment of a plurality of members (3), or any of its strip stress special steel strip (1) and flatness in cold rolling multistage rolling stand (2) Methods and apparatus for measurement control one, is detected by comparing stress vector and (8) a predetermined reference curve (9) (10) flatness error, then strip width elapsed flatness error (10) is ( Adjustment of each flatness error related quantities that are decomposed stress vector of related quantities in (8) can be approximated mathematically analysis component (11) was determined by the real number (C1 ... Cx) for 7) to ensure control and precise control by supplied (12a, 12b) to the control module that comes with each operating a (3) members.
