Abstract

Procédé de chauffage par induction d'une pièce métallique dans lequel on chauffe de façon continue une pièce allongée au moyen d'une bobine de chauffage par induction. Il est caratérisé par le fait que l'on maintient la partie terminale de la pièce et la bobine de chauffage par induction dans un état où il n'y a entre elles aucun mouvement relatif, pour effectuer un chauffage préliminaire de la partie terminale de la pièce pendant un temps prédéterminé et obtenir ainsi une distribution pratiquement uniforme de température de chauffage sur toute la pièce. Application aux tubes d'acier.
