Abstract

: Bobine de chauffage inductif. Un tube de refroidissement (?) est incorporé dans chaque conducteur (C1) de la bobine, Le transport du courant dans ce conducteur est réparti entre des brins (B1...B12) qui restent appliqués en contact thermique contre ce tube même dans des zones de transposition ou de vrillage où ce conducteur a subi des déformations particulèrement intenses. Ce conducteur présente au moins un vrillage d'un demi-tour entre les bornes électriques de la bobine. L'invention s'applique notamment en sidérurgie, pour le chauffage au défilé de rives de produits plats. FIGURE A PUBLIER : Fig. 7
