Abstract

L'invention concerne un procédé permettant de faire fonctionner un train de laminoir, selon lequel les paramètres d'une cage de laminoir (2) du train de laminoir sont prescrits à un ordinateur de commande (3) d'un train de laminoir. Dans le cadre du calcul d'un plan de passes, l'ordinateur de commande (3) fixe des grandeurs (F, δF, G, δs, V) décrivant une passe de laminage de la cage de laminoir (2), qui décrivent la fente de laminage produite et son asymétrie, en relation avec des données initiales (b, d, T) d'un produit plat (1) à laminer et des données relatives à la cage. Les données initiales (b, d, T) contiennent au moins la largeur (b), l'épaisseur moyenne (d) et la résistance moyenne du produit à laminer (1). L'ordinateur de commande (3) détermine dans le calcul du plan de passes, au moyen des données initiales (b, d, T), des données relatives à la cage et des grandeurs (F, δF, G, δs, V) fixées, un biseau de sortie (K) attendu et/ou ou une lame de sabre (K') attendue pour le produit à laminer (1). L'ordinateur de commande (3) modifie selon une stratégie de biseautage qui lui est prescrite de l'extérieur au moins une des grandeurs (F, δF, G, δs, V) pour que le biseau de sortie (K) obtenu approche au moins un biseau de sortie théorique et/ou que la lame de sabre (K') approche au moins une lame de sabre théorique. L'ordinateur de commande (3) transmet les grandeurs modifiées obtenues (F, δF, G, δs, V) à un dispositif d'automatisation de base (8) de la cage de laminoir (2), de sorte que le produit à laminer (1) est laminé dans la cage de laminoir (2) conformément aux grandeurs modifiées (F, δF, G, δs, V).
