Abstract

L'invention concerne une unité de rouleau de guidage de barre (33, 33a) destinée au guidage d'une barre métallique dans une machine pour la coulée continue (2). L'unité comporte un rouleau de guidage de barre (26) qui peut être ajusté individuellement contre la barre, un support de rouleau (28, 28a), un dispositif de réglage (30) et une traverse (32, 32a). Le rouleau de guidage de barre (26) qui peut être ajusté individuellement est relié au support de rouleau (28, 28a) et le dispositif de réglage (30) est relié au niveau d'une extrémité au support de rouleau (28, 28a) et au niveau de l'autre extrémité à la traverse (32, 32a). L'unité comprend en outre un segment de guidage de barre (101) et un guidage de barre (8). On obtient une unité de rouleau de guidage de barre (33, 33a) particulièrement avantageuse quand le dispositif de réglage (30) est relié de manière mobile en translation et en rotation à la traverse (32, 32a) ou au support de rouleau (28, 28a) au moyen d'au moins un support (43).
