Abstract

L'invention concerne un procédé de laminage à chaud. Même en cas d'anomalie avant, pendant ou après l'assemblage des pièces métalliques, il n'est pas nécessaire d'interrompre la ligne de production. Lorsqu'à l'entrée d'un laminoir de finition (26), l'extrémité avant d'une pièce métallique suivante doit être assemblée avec l'extrémité arrière (10B) d'une pièce métallique précédente aux fins de laminage continu avec cette pièce (10), on décide s'il est possible de conduire une opération de laminage sans fin avant et après l'assemblage. Si cette opération est impossible, l'assemblage est suspendu et la pièce métallique suivante (12) est stoppée. Ainsi, après le passage de l'extrémité arrière (10B) de la pièce métallique précédente dans le laminoir de finition (26), la pièce métallique suivante (12) est retransférée et soumise au laminage de finition avec un réglage de laminage discontinu, et si une anomalie survient dans la partie assemblée après l'assemblage, la partie assemblée (11) est coupée, entre la machine d'assemblage et le laminoir de finition (26), et le matériel à laminer est introduit dans le laminoir de finition avec un réglage de laminage discontinu.
