Abstract

L'invention concerne un dispositif de guidage de barre (1), notamment pour une installation de coulée continue de brame d'acier, comprenant un certain nombre de segments (2) qui supportent une barre (3) sur deux côtés (4, 5) opposés l'un à l'autre au moyen d'éléments de soutien (6, 7). Selon l'invention, pour guider la barre (3) dans un sens de transport (F), les éléments de soutien (6, 7) sont disposés dans au moins un cadre inférieur (8) et au moins un cadre supérieur (9), lesdits cadres (8, 9) étant disposés sur au moins un longeron central (10). L'invention facilite le remplacement de segments ou de parties de ceux-ci en ce que des moyens (11) sont prévus pour déplacer ledit cadre supérieur (9) et/ou ledit cadre inférieur (8) par rapport audit longeron central (10) dans le sens de transport (F) ou à l'opposé de ce dernier.
