Abstract

L'invention concerne un agencement de support d'une installation de coulée continue destinée à fabriquer des barres de forme rectangulaire, ledit agencement de support comprenant un ensemble latéral de rouleaux de support (2) agencé sous une coquille (1) et destiné à soutenir une barre sortant de la coquille (1). L'ensemble de rouleaux de support (2) présente au moins deux rouleaux de support (4) fixés de manière superposée sur un support commun (3). Un élément de retenue (5) est accouplé à la coquille (1), une zone supérieure du support (3) étant raccordée de manière articulée audit élément de retenue par l'intermédiaire d'un guidage horizontal (6) et une zone inférieure du support (5) étant raccordée de manière articulée audit élément de retenue par l'intermédiaire d'une articulation (7), au moyen d'un élément de guidage (8) orienté de manière inclinée vers le bas. L'ensemble de rouleaux de support (2) est ainsi protégé contre la surcharge.
