Title
(EN) SYSTEM FOR CONTROLLING A ROLLING MILL AND METHOD OF CONTROLLING A ROLLING MILL
(FR) SYSTEME DE COMMANDE D'UN LAMINOIR ET PROCEDE DE COMMANDE D'UN LAMINOIR
Abstract
(EN)
The invention generally relates to a method of controlled rolling of a metal strip moving through a rolling mill. The method comprises: monitoring a plurality of input control parameters; and generating a plurality of responsive operational control parameters in the rolling mill to selectively control the rolling mill and selectively control a plurality of output parameters of the rolling mill. A control system for controlled rolling of a metal strip moving through a rolling mill is also provided.
(FR)
L'invention concerne un procédé permettant de commander le laminage d'une bande métallique traversant un laminoir. Ce procédé consiste à surveiller une pluralité de paramètres de contrôle d'entrée et à produire une pluralité de paramètres de contrôle opérationnel dans le laminoir pour commander de manière sélective le laminoir et une pluralité de paramètres de sortie du laminoir. L'invention concerne également un système de commande destiné au laminage d'une bande métallique traversant un laminoir.
