Abstract

L'objectif de l'invention est de permettre la production d'aciers biphasés par un refroidissement contrôlé en deux étapes du feuillard laminé à chaud, à l'issue du formage, quelle que soit la longueur de la section de refroidissement de l'installation de laminage de coulée continue et quelles que soient les conditions locales. A cet effet, outre le maintien de la composition chimique de l'acier de base dans des limites définies de façon précise, l'invention se caractérise en ce que le refroidissement en deux étapes est effectué d'une température de laminage final Tfinish telle que A3 - 100 K < Tfinish < A3 - 50 K à une température d'enroulement Tcoiling < 300 °C (< température de départ du martensite), la vitesse de refroidissement V1,2 au cours des deux étapes de refroidissement étant comprise entre 30 et 150 K/s, de préférence entre 50 et 90 K/s. La première étape de refroidissement a lieu jusqu'à ce que la courbe de refroidissement entre dans la plage de la ferrite, puis la chaleur dégagée par la conversion de l'austénite en ferrite est utilisée pour maintenir de façon isothermique la température de feuillard atteinte Tconst. pendant un temps de maintien ≤ 5 s jusqu'au début de la seconde étape de refroidissement.
