Title: Proceso simplificado de la laminacion en caliente de un acero estructural con titanio como elemento microaleante.
Inventor: LOPEZ SERRANO VICTOR
IPC: C21D8/02

Granted: 2011-11-08
Abstract: Proceso simplificado de laminación en caliente
de un acero estructural con titanio como elemento microaleante. 
     Simplificación del proceso de laminación en
caliente en un tren de laminación de aceros estructurales
conteniendo Ti y N y con relación Ti/N comprendida entre 1 y 3,
preferentemente próxima a 2. El tamaño de grano austenítico
recristalizado se reduce muy poco entre pasadas, ya que se parte de
un grano austenítico inicial muy pequeño correspondiente a la
temperatura de recalentamiento. La presente invención propone un
menor número de pasadas. El afino del grano ferrítico final se
obtendría por endurecimiento previo de la austenita, lo que se
consigue realizando las últimas pasadas a temperaturas próximas a
A_{r3}, seguido de enfriamiento inmediato tras el paso por el tren
de laminación, a una velocidad de enfriamiento próxima a 20ºC/s.
