The invention concerns a refractory assembly for a device for regulating a pouring flow rate. Downstream from a pouring channel (7), it is comprised of at least two refractory plates (1, 2) perpendicular to one axis of the channel (Z-Z) and equipped with the respective orifices (10, 20). The device includes, upstream from the plates, means for injecting a fluid (F) capable of cooperating mechanically with the pouring (C). According to the invention, this injection is effected upstream from the plates and in an angular sector of the channel (7) less than 360~, in the direction of displacement (X-X) of the sliding plate (1) toward its stop position.

Ensemble réfractaire pour un dispositif destiné à réguler une vitesse de coulée, qui est situé en aval d'un canal de coulée (7). Ledit ensemble comporte au moins deux plaques réfractaires (1, 2) perpendiculaires à un axe du canal (Z-Z) et équipées d'orifices respectifs (10, 20). En amont des plaques, ledit dispositif comporte un moyen d'injection d'un fluide (F) capable de coopérer mécaniquement avec la coulée (C). Selon la présente invention, cette injection est effectuée en amont des plaques et dans un secteur angulaire du canal (7) inférieur à 360·, dans le sens de déplacement (X-X) de la plaque coulissante (1) vers sa position d'arrêt.
