Abstract

L'invention concerne un procédé permettant d'améliorer à la fois la capacité de production d'un four (6) et la qualité métallurgique des produits traités dans ce four dans lequel un produit métallique (1) de préférence plat défile dans ce four successivement à travers une zone de réchauffage (8) du produit (1) puis une zone de chauffage (9) du produit dans laquelle sont disposés des moyens de chauffage. On dispose au moins un brûleur oxy­combustible dans la zone de préchauffage (4) du four, la distance entre l'axe de la flamme à la sortie du brûleur oxy-combustible et le plan dans lequel défile ledit produit dans le four (6) étant comprise entre 2 D et 6 D, de préférence entre 2,5 D et 5 D, D étant le diamètre de l'orifice équivalent dudit oxy-brûleur (7).
