Patent

CA 2648032

The invention relates to a strand guide roller (100) of a strand guide device for guiding a cast strand (200). The strand guide roller comprises at least one first and one second sectional roller arranged axially next to one another, wherein the first sectional roller has a roller journal (112-1) on its end face facing the second sectional roller. In addition, the strand guide roller comprises a centre bearing (120-1, 120-2) between the two sectional rollers for accommodating and mounting the roller journal of the first sectional roller. In order to improve the strand guide by an enlarged supporting surface for the strand (200), it is proposed according to the invention that the first and the second sectional rollers be connected to one another via a push-in connection outside the centre bearing. The centre bearing is then designed according to the invention merely as an unsplit individual bearing with a substantially smaller window width compared with a split centre bearing.

L'invention concerne un rouleau de guidage de barre (100) d'un dispositif de coulée continue pour guider une barre coulée (200). Le rouleau de guidage de barre comprend au moins un premier et un deuxième rouleau partiel disposés axialement l'un à côté de l'autre, le premier rouleau partiel présentant un tourillon de rouleau (112-1) sur son côté frontal tourné vers le deuxième rouleau partiel. En outre, le rouleau de guidage de barre comprend un palier central (120-1, 120-2) entre les deux rouleaux partiels, pour recevoir et supporter le tourillon de rouleau du premier rouleau partiel. Afin d'améliorer le guidage de barre par une plus grande surface d'appui pour la barre (200), le premier et le deuxième rouleau partiel sont connectés l'un à l'autre selon l'invention par le biais d'une connexion par enfichage à l'extérieur du palier central. Le palier central est alors uniquement réalisé selon l'invention en tant que palier unique non divisé, avec une largeur de fenêtre nettement plus petite par comparaison avec un palier central divisé.
