Abstract

L'invention concerne les dispositifs pour la régulation de l'épaisseur de produits laminés. Le dispositif est doté d'un module 24 de correction du volume de fluide dans le circuit hydraulique fermé d'écartement des cylindres de travail, et d'un module logique 25 raccordé au module de correction. La quantité de fluide dans le circuit hydraulique fermé est changée en fonction de la valeur du signal d'écart de l'épaisseur du laminé par rapport à la valeur prescrite. Le passage du signal dans le module de correction est interdit ou autorisé par un module spécial 21 de retard dû à la position aval de la jauge d'épaisseur. Application automatisation de laminoirs à tôles.
