To bring about a direct effect on the fluid streams exiting the mould dip tube (2) of moulds in continuous casting moulds (1) of a continuous casting plant for casting liquid metals, in particular liquid steel materials for producing slab and thin slab products with format widths of 750 to 3500 mm and format thicknesses of 30 to 500 mm, said casting plant being equipped with an electromagnetic braking device for improving the product quality, it is proposed to dispose at least two poles (10) per mould broad side (3) symmetrically with respect to the perpendicular reference line (4) of the mould dip tube (2) such that the primary axes (12) of the poles' outlet cross section (11a) are aligned at a specific angle (.alpha.1, and .alpha.2) relative to the perpendicular reference line (4) of the mould dip tube (2).

L'invention concerne les lingotières de coulée continue (1) d'une installation de coulée continue destinée à la coulée de métaux liquides, en particulier de matériaux liquides à base d'acier pour la production de brames et de brames minces avec des largeurs de 750 à 3500 mm et des épaisseurs de 30 à 500 mm, qui est équipée pour améliorer la qualité du produit d'un dispositif de freinage électromagnétique. Pour agir directement sur les jets liquides sortant du tube plongeur (2) de la lingotière (1), il est proposé, selon l'invention, de disposer sur chaque grand côté (3) de la lingotière au moins deux pôles (10) placés symétriquement par rapport à la droite verticale de référence (4) du tube plongeur (2) afin que leurs axes principaux (12) de la section de sortie (11a) forment avec la droite verticale de référence (4) du tube plongeur (2) un angle déterminé (a1 ou a2).
