Abstract

L’invention porte sur un procédé de préchauffage d’au moins un cylindre de travail de laminage comportant des phases de : détermination d’un profil de dilatation thermique cible, détermination d’un profil de température moyenne effective de segments longitudinaux du cylindre de travail, et d’un profil de température moyenne cible ;activation d’une pluralité d’inducteurs répartis le long du cylindre de travail pour réduire un écart entre la température moyenne effective et la température moyenne cible. Figure pour l’abrégé : Fig.1A
