CA 2547188

The invention relates to a reel driving device for rolling mills, said device comprising an upper driving roll (1') and a lower driving roll (1). The aim of the invention is to improve said reel driving device in such a way that the rolled product is not damaged by the rolls (1, 1'), that the rolled product does not adhere to the rolls (1, 1'), and that the driving rolls (1, 1') can be economically created as standard expendable parts. To this end, the lower driving roll (1) comprises a steel roll axle (2) to which a cast envelope (3) adheres and/or onto which said cast envelope is shrunk and/or the upper driving roll (1') comprises a cast envelope (3') held between two clamping elements (5) arranged on an axle (2').

L'invention concerne un dispositif d'entraînement d'enrouleuse pour laminoirs, qui comprend un rouleau d'entraînement supérieur (1') et un rouleau d'entraînement inférieur (1), lequel doit être développé de façon telle que le produit laminé ne soit pas endommagé par les rouleaux (1, 1'), que le produit laminé ne reste pas collé aux rouleaux (1, 1') et que les rouleaux d'entraînement (1, 1') puissent être réalisés de façon économique sous forme de pièces d'usure classiques. A cet effet, il est proposé que le rouleau d'entraînement inférieur (1) comporte un axe (2) en acier sur lequel est collée et/ou emmanchée une enveloppe coulée (3) et/ou que le rouleau d'entraînement supérieur (1') présente une enveloppe coulée (3') qui est maintenue entre deux éléments de serrage (5) disposés sur un axe (2').
