Abstract (en)
[origin: WO2019215045A1] The invention relates to a method for dynamic nip control during flexible rolling of metallic strip material, having the following steps: specifying (V10) a target thickness profile (1) having defined target corner points (E) and profile sections (2', 2'', 3', 3'') therebetween, each pair of profile sections which adjoin at a target corner point having different average gradients; flexibly rolling (V40) the strip material (11) according to the target thickness profile (1); measuring (V50) an actual thickness profile (14) of the flexibly rolled strip material (11'); determining (V60) actual corner points (E') corresponding to the target corner points (E) and actual intermediate points (S') corresponding to the target intermediate points (S); determining (V70) corner point comparative values (ΔD, ΔL) from the target corner points (E) and the corresponding actual corner points (E') and intermediate point comparative values (ΔD', ΔL') from the target intermediate points (S) and the corresponding actual intermediate points (S'); controlling (V80) a nip (12) in accordance with the corner point comparative values (ΔD, ΔL) and the intermediate point comparative values (ΔD', ΔL').
