Abstract

SECTION DE PRECHAUFFAGE A FLAMME DIRECTE POUR LIGNE CONTINUE DE TRAITEMENT DE BANDES METALLIQUES Section de préchauffage à flamme directe pour lignes continues de traitement de bandes métalliques (B) comprenant une zone de liaison entre une zone active (14) équipée de brûleurs aptes à fonctionner en mode dit sans flamme et une zone récupérative (11) de préchauffage de la bande par échange avec les fumées de combustion provenant de la zone active, ladite zone de liaison ayant des chambres (18, 19) aptes à orienter l’écoulement des fumées de sorte qu’elles s’écoulent frontalement par rapport à la bande en sortie de la zone active et en entrée de la zone récupérative selon la direction d’écoulement des fumées. Figure pour l’abrégé : 7DIRECT FLAME PREHEATING SECTION FOR CONTINUOUS METAL STRIP TREATMENT LINE Direct flame preheating section for continuous metal strip processing lines (B) comprising a connecting zone between an active zone (14) equipped with burners capable of operating in so-called flameless mode and a recuperative zone (11) for preheating the strip by exchange with the combustion fumes coming from the active zone, said connection zone having chambers (18, 19) capable of directing the flow of the fumes from so that they flow frontally with respect to the strip at the exit from the active zone and at the entrance to the recuperative zone in the direction of flow of the fumes.
