Abstract

Procédé et installation de laminage et de refroidissement de barres en acier à teneur en carbone moyenne à élevée. La barre est laminée à grande vitesse et à température élevée et elle est aussitôt enroulée et déposée sur un convoyeur. De l'eau chaude est projetée sur les spires pour ramener leur température à une valeur légèrement supérieure à celle du point de transition A3 . Puis on fait débuter la transformation de l'acier tout en le refroidissant à l'air et pendant que la plus grande partie de la barre se transforme, on la refroidit encore plus rapidement Application à la fabrication de barres d'acier.
