Abstract
Procédé et dispositif de mise en oeuvre pour homogénéiser en température des produits métalliques, notamment des brames d'acier, destinés au laminage et ayant préalablement été soumis à un réchauffage non parfaitement homogène. L'invention consiste à faire défiler les produits 1 lors de leur transfert du four de réchauffage vers le laminoir, dans la zone d'action 9 d'un inducteur électromagnétique à champ glissant 5, 6 et à ne déclancher cette action que lors du passage des parties froides ou traces noires 2 présentes sur les produits 1. Ces traces noires sont détectées en amont de l'inducteur par un capteur de température 12 relié à un boitier de commande 14 contrôlant et regulant la mise en fonctionnement séquentielle de l'inducteur. L'invention procure un chauffage efficace et très sélectif en permettant une localisation précise de la zone de chauffe sur une partie prédéterminée du produit à traiter. Elle est particulièrement bien appropriée au traitement des produits de grandes dimensions, tels que les brames, en vue de l'atténuation ou de la suppression des taches noires, qu'elles présentent généralement à leur sortie du four de réchauffage.
