Abstract

On coule l'acier dans un moule (1) dont au moins la section de sortie présente une largeur inférieure ou égale à 60 mm, et on extrait de ce moule une brame (2) ayant une épaisseur inférieure à 60 mm et présentant une peau solidifiée. On soumet la brame à un refroidissement secondaire au cours duquel on forme une couche in­ interrompue de liquide de refroidissement sous pression (3) sur au moins une partie de la surface de la brame, et on assure l'écoule­ ment du liquide de refroidissement sur la surface de la brame dans le sens de la progression de celle-ci.
La vitesse de coulée est supérieure à 3 m/min, et est de préférence comprise entre 6 m/min et 20 m/min.
On refroidit la brame, pendant le refroidissement secondaire, jusqu'à une température de surface inférieure à 800°C, et de préférence inférieure à 600°C. La brame mince peut être directement laminée à chaud.
