CA 2300388

The invention relates to an ingot arrangement (1) in a continuous casting installation, comprising an ingot mould (2A) and an oscillating holding device (4) used for causing said ingot mould to swing when in a casting position (2a). The ingot arrangement consists, in a separable manner, of an interchangeable part (2a) and a stationary part (4, 11, 12, 12', 71). To replace the interchangeable part, it is separated from the stationary one and moved using a conveying means (23), at least along a partial path, from its position of operation into an area (29) beneath the casting position (2a). This enables, especially in multiline casting installations, the interchangeable part to be transported during the casting process and, for example, along paths comprising straight (23') or arciform segments (23''), to any purposefully selected position (2b) and to be replaced by a new interchangeable part by reversing the steps of the method. Such a method allows for an interchangeable part to be replaced in multiline installations with no interference with the casting process in any adjacent ingot arrangement.

L'invention concerne un agencement de lingotière (1) d'une installation de coulée continue, qui comprend une lingotière (2a) et un dispositif de maintien oscillant (4) servant à faire osciller la lingotière en position de coulée (2a) et qui est composée, de manière séparable, d'une pièce interchangeable (2a) et d'une pièce stationnaire (4, 11, 12, 12', 71). Pour remplacer la pièce interchangeable, on la sépare de la pièce stationnaire et on la déplace, au moyen d'un dispositif de transport (23), au moins le long d'une trajectoire partielle, de sa position de service dans un espace (29) en dessous de la position de coulée (2a). On peut ainsi, en particulier pour des installations de coulée à plusieurs lignes, transporter la pièce interchangeable, pendant la coulée et, par exemple, le long de trajectoires à segments rectilignes (23') ou en arc (23''), vers une position quelconque sélectionnée à dessein (2b), et la remplacer par une nouvelle pièce interchangeable en inversant ces étapes de procédé. Il est ainsi possible de remplacer une pièce interchangeable dans des installations à plusieurs lignes sans nuire à la coulée au niveau d'un agencement de lingotière voisin.
