Abstract

L'installation de coulée continue des métaux, de l'acier en particulier, dan s laquelle la busette immergée (8) est entourée par un inducteur électromagnétique annulaire (1) à champ magnétique tournant autour de l'axe de coulée destiné à entraîner en rotation axiale avec lui le métal en fusion, s e caractérise en ce que, cet inducteur étant de type polyphasé à champ magnétique traversant, pourvu d'une paire de pôles saillants (3) par phase, chaque pôle saillant présente à son extrémité en regard de la busette un rétrécissement latéral (12) qui augmente la distance séparant les extrémités polaires (4) entre elles. On réalise ainsi un inducteur de grande compacité à forte puissance, délivrant un champ traversant intense jusque dans la partie centrale de la busette et ce avec un courant primaire à fréquence élevée de manière à obtenir une mise en rotation efficace du métal liquide en transit dans la busette. L'invention s'applique avantageusement à la coulée continue de brames mettant en oeuvre une busette immergée à ouïes de sorties latérale s.The continuous casting plant for metals, in particular steel, in which the immersed nozzle (8) is surrounded by an annular electromagnetic inductor (1) with a magnetic field rotating around the casting axis intended to drive into axial rotation with it the molten metal, is characterized in that, this inductor being of the polyphase type with a traversing magnetic field, provided with a pair of salient poles (3) per phase, each salient pole having at its end opposite the nozzle a lateral narrowing (12) which increases the distance separating the polar ends (4) between them. A highly compact high power inductor is thus produced, delivering an intense through field into the central part of the nozzle and with a high frequency primary current so as to obtain efficient rotation of the liquid metal in transit through the nozzle. nozzle. The invention is advantageously applied to the continuous casting of slabs using a submerged nozzle with lateral outlet openings s.
