Abstract

Procedimiento para producir banda laminada en caliente a partir de material de laminación fundido en colada continua y/o prelaminado en la zona austenítica, con estructuras y propiedades homogéneas, a partir de acero sin aleación o con aleaciónbaja, enel que el material de laminación es laminado en caliente en paso continuo en un tramo de laminación de acabado en dos o más pasadas en la zona austenítica, partiendo de una temperatura T >= Ar3 + 30º C, con un grado de deformación total de eh >= 30 %, y a continuación es laminado en caliente en varias pasadas en la zona ferrítica con un grado de de formación total de eh >= 60 % y seguidamente es bobinado, caracterizado porque el material de laminación es laminado en caliente continuamente en el tramo de acabado en forma consecutiva en la zona austenítica, en la zona de dos fases y en la zona ferrítica, porque el material de laminación es enfriado intensivamente después de cada pasada durante la laminación en caliente por medio de la utilización selectiva de grupos de refrigeración colocados en el tramo de acabado, y porque el enfriamiento intensivo se termina después de concluida la transformación ferrítica.
