The invention relates to a method for processing a continuously cast metal slab or strip, in which the slab or strip is passed between a set of rotating rolls of a rolling mill stand in order to roll the slab or strip. According to the invention, the rolls of the rolling mill stand have different peripheral velocities, and the difference in peripheral velocity is at least 5% and at most 100%, and the thickness of the slab or strip is reduced by at most 15% for each pass. The invention also relates to metal plate or strip produced using this method.
L'invention concerne un procédé de traitement d'une plaque ou d'une bande de métal fondu, dans lequel la plaque/bande est soumise au laminage par passages successifs entre les cylindres du laminoir. Selon l'invention, les cylindres du laminoir tournent à des vitesses périphériques différentes, la différence de vitesse périphérique étant de 5 % min. et 100 % max.. L'épaisseur de la plaque/bande est réduite d'au moins 15 % à chaque passage. Par ailleurs, l'invention concerne une bande/plaque de métal produite au moyen de ce procédé.
