Abstract

L'invention concerne un procédé de régulation de l'épaisseur d'un produit plat en cours de laminage dans un laminoir à chaud et le dispositif de régulation correspondant Au niveau de chacune des cages du laminoir sur laquelles on opère le réglage, on maintient la pression de laminage constante, on mesure l'entrefer, on déterminé l'écart entre l'entrefer mesuré et une valeur de consigne correspondant à l'épaisseur du produit et on détermine la correction nécessaire de la valeur de la traction exercée sur la tôle entre la cage considérée et la cage amont pour ramener l'entrefer à sa valeur de consigne. Enfin, on effectue cette correction de la traction entre la cage considérée et la cage amont. L'invention s'applique au laminage de tôles et feuillards.
