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 chann el (Z-Z) and equipped with the respective orifices (10, 20). The device include s, 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.
