Dans cette invention, une unité de mesure de cambrure de pointe calcule une valeur de mesure de cambrure de pointe au niveau d'une partie pointe de matériau de laminage sur la base d'une quantité de méandres du matériau de laminage détectée par un détecteur de quantité de méandres. Une unité de calcul de nivellement de rectification de cambrure calcule une quantité de nivellement de rectification de cambrure sur la base de la valeur de mesure de cambrure de pointe. Une unité de définition de nivelage de pointe définit une longueur de commande de nivellement de pointe et une quantité de correction de nivellement de pointe pour réduire la cambrure de pointe pour un dispositif de nivellement de réduction de chaque cage de laminage. Une unité de commande de nivellement de réduction ajuste le dispositif de nivellement de réduction à une position d'ajout de quantité de correction de nivellement de pointe avant que le matériau de laminage n'entre dans chaque cage de laminage et ajuste la position du dispositif de nivellement de réduction de sorte que la quantité de correction de nivellement de pointe diminue progressivement après que la longueur de laminage au niveau de chaque cage de laminage ait atteint la longueur de commande de nivellement de pointe.
