Abstract (en)
[origin: WO9120168A1] A cooling pipe (T) is incorporated in each of the coil's conductors (C1). Current flow in this conductor is split between cords (B1...B12) which remain in thermal contact with the pipe even in transposition or twist areas where the conductor has been particularly intensely deformed. Said conductor has at least one 180 twist between the electrical terminals of the coil. The coil can be used particularly in metallurgy for on the fly heating of the edges of flat materials.
Abstract (fr)
Un tube de refroidissement (T) 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.
