Claims (4)

  1. Segment de guidage (3a, 3b) équipé de rouleaux dans une installation de coulée continue, dans lequel au moins certains rouleaux comprennent respectivement au moins deux corps de rouleaux alignés (4, 5, 6) avec des tourillons terminaux (4b, 6a) montés dans des roulements internes (6a, 8a) et externes (7a, 10a), les roulements internes (4b, 5a, 5b, 6a) se présentant en roulements libres sous la forme de roulements à rouleaux complets très performants et les roulements externes (7a, 10a) se présentant en roulements fixes, caractérisé en ce que, entre les deux corps de rouleaux (4, 6) et dans l'alignement avec eux, est monté à flottement axial un autre corps de rouleau (5) avec ses deux tourillons terminaux (5a, 5b) dans des feulements libres (8b, 9a) sous la forme de roulements de rouleaux complets très performants, la mobilité axiale libre du corps de rouleau central (5) est limitée par des butées (11, 12a, 12b, 13) efficaces entre les tourillons intérieurs (4b, 6a) des corps de rouleaux externes (4, 6) et les deux tourillons (5a, 5b) du corps de rouleau central (5).
  2. Segment de guidage selon la revendication 1, caractérisé en ce que les roulements fixes (7, 10) se présentent sous la forme de roulements pendulaires.
  3. Segment de guidage selon la revendication 1 ou 2, caractérisé en ce que les deux tourillons externes (5a, 5b) du corps de rouleau central (5) et/ou les tourillons internes (4b, 6a) des corps de rouleaux externes (4, 6) portent, sur leurs côtés frontaux, les butées (11, 12a, 12b, 13) conformées en plaques d'appui, qui limitent le jeu axial du corps de rouleau central (5) de manière qu'à l'état froid des corps de rouleaux (4, 5, 6), il soit inférieur ou égal à la mobilité axiale autorisée des roulements libres du corps de rouleau central (5) et supérieur à la somme des dilatations thermiques axiales maximales des corps de rouleaux (4, 5, 6).
  4. Segment de guidage selon l'une quelconque des revendications 1 à 2, caractérisé en ce que les bagues des roulements libres des corps de rouleaux externes (4, 6) sont décalées axialement l'une vers l'autre à leur état froid de sorte qu'elles se trouvent dans leur position de roulement optimale à l'état chaud.
