The invention is directed to a strand guide for producing strands in the form of slabs, blooms, and billets resulting in a central running of the strand in the strand guide stands and accordingly in highly reliable casting - even at casting speeds of up to 6m/min. This high level of casting reliability is achieved by means of strand guide stands in which the rolls have a slightly concave surface line (cambering of the strand) resulting in the surprising elimination of the weaving motion of the strand in the direction of the narrow sides and accordingly ensuring that the strand runs centrally with reference to the center axis in its main direction of progress.
L'invention concerne un guide pour métal coulé en continu qui permet de produire du métal coulé en continu, sous forme de brames, de blooms et de billettes. Ce guide pour métal coulé en continu permet à celui-ci de passer de manière centrée dans les cadres de guidage, ce qui permet d'atteindre une grande fiabilité de coulée, même à des vitesses de coulée allant jusqu'à 6 m/mn. A cet effet, les cadres de guidage comportent des rouleaux qui suivent une génératrice légèrement concave (bombage du métal coulé), ce qui élimine le risque d'oscillation de ladite barre en direction des petits côtés, garantissant ainsi que le métal coulé passe de manière centrée par rapport à l'axe médian, dans la direction de sa trajectoire.
