In a continuous casting of steel slab, a molten steel is provided having an oxygen concentration of not more than 35 ppm and is supplied from a tundish into a continuous casting mold through a straight immersion nozzle having an open end at the forward end thereof, the mold consisting of a combination of a pair of narrow face mold walls and a pair of wide face mold walls. A traveling magnetic field generating device is disposed on a central area of the outer surface of the wide face mold walls. While the open forward end of the nozzle is positioned in the magnetic field region of the traveling magnetic field generating device, a traveling magnetic field which is perpendicular to the wide face mold walls and which is traveling upward is applied to a flow of the molten steel discharged from the nozzle, thereby controlling the flow. Preferably, an upper or lower static magnetic field generating device or both of them may be also used.

Dans une installation de coulée continue, un acier en fusion est produit avec une concentration en oxygène d'au plus 35 ppm; l'acier est déversé par un panier de coulée dans un moule continu par l'intermédiaire d'une lance droite en immersion dont l'extrémité débouche dans un moule, celui-ci consistant en la combinaison d'une paire de parois à face étroite et d'une paire de parois à face large. Un dispositif générateur de champ magnétique se déplace le long de la partie centrale de la surface extérieure des parois larges du moule. Pendant que l'extrémité ouverte de la lance est positionnée dans la région du champ magnétique en déplacement longitudinal, un champ magnétique ascendant et perpendiculaire aux parois à large face du moule est appliqué au métal en fusion s'écoulant de la lance pour en contrôler le débit. De préférence, on pourra aussi utiliser un générateur de champ magnétique statique descendant ou ascendant, ou les deux.
