Abstract

L'invention concerne un procédé et un dispositif d'équilibrage de la température de rouleaux (3, 5, 7), en particulier de rouleaux (3, 5, 7) d'une cage de laminoir (1). La cage de laminoir (1) comprend essentiellement des rouleaux de travail (3), des rouleaux de support (7) et éventuellement au moins un rouleau intermédiaire (5). Les rouleaux intermédiaires (5) sont situés avantageusement entre les rouleaux de travail (3) et les rouleaux de support (7). Pour équilibrer la température des rouleaux (3, 5, 7), les rouleaux (3, 5, 7) sont exposés à un moyen d'équilibrage de température et/ou une source de chauffage (17). Selon l'invention, les rouleaux de travail (3) et l'un au moins des rouleaux intermédiaires (5) et/ou éventuellement l'un au moins des rouleaux de support (7) sont équilibrés en température. L'équilibrage en température des rouleaux de travail (3) et des rouleaux intermédiaires (5) permet d'effectuer notamment un ajustement rapide de la température du profil de laminage au profil du produit laminé (2), en particulier dans la zone du traitement de la matière. Cela conduit à une amélioration de la planéité du produit laminé (2) après le processus de laminage.
