Abstract

La présente invention propose un système et une méthode de contrôle de l'intégrité d'un four contenant des matières en fusion, et qui donnent un avertissement préalable d'une rupture potentielle ou d'un état d'équipement opératoire en utilisant des outils statistiques multivariés. De multiples modèles à plusieurs variables sont utilisés en association pour fournir un statut du procédé et gérer une dérive du procédé à long terme. Les divers résultats du modèle sont alors utilisés conjointement pour arriver à une conclusion, laquelle indique que le système permet un arrêt automatique du procédé pour empêcher une perte catastrophique de l'intégrité du four.
