Abstract
Dans un procédé de laminage à froid d'une bande métallique (B) entre les cylindres de cages de laminage (C1, C2, C3) disposées l'une à la suite de l'autre, on apporte en temps réel une modification à la consigne de serrage des cylindres d'au moins une (C2, C3) desdites cages (C1, C2, C3) pour compenser les défauts de faux-rond des cylindres de ladite cage (C2, C3) et on évalue ladite modification en analysant en fréquence un signal de mesure de traction de la bande (B) immédiatement en amont de ladite cage (C2, C3) et en extrayant du signal de mesure de traction, les variations périodiques du signal dont les fréquences correspondent aux vitesses de rotation desdits cylindres, de manière à obtenir un signal de compensation proportionnel aux variations périodiques. On améliore sensiblement le temps de réponse de la régulation de compensation et l'homogénéité en épaisseur de la bande (B) en sortie de laminage. Le dispositif de compensation (P'2, P'3) est relié aux moyens de serrage (A2, A3) de la cage (C2, C3) et à un capteur de traction (T2, T3) situé immédiatement en amont de la cage (C2, C3).
