Abstract

L'invention concerne la production d'aciers à deux phases (2) obtenus par refroidissement ciblé après la dernière étape de déformation dans une cage de laminoir (1). Selon ce procédé, on ajuste une structure à deux phases composée de 70 à 90 % de ferrite et de 30 à 10 % de martensite. Afin de ne pas dépendre de la géométrie de l'acier et de la vitesse du feuillard, il est prévu selon l'invention d'effectuer le refroidissement sous forme de refroidissement par dispersion, dans une section de refroidissement (6) avec des étages d'eau de refroidissement (7) placés les uns à la suite des autres.
