Method and apparatus for continuous casting, more particularly continuous casting of steel that can easily provide steel of good quality that has no central segregation and central porosity. In other words, in the method and apparatus, central defects are to be eliminated by identifying the solidifying conditions in the full range from the meniscus (the surface position of the upper portion of molten metal) to the crator end (a final solidifying position), and more particularly the pressure drop of liquid phase caused by the liquid-phase current between dendrites induced in turn by the solidifying contraction in a casting direction in the solid-liquid coexisting phase based on the operating conditions such as the type (profile) of continuous casting machines, type of steel, cross-sectional configuration/size of a cast piece and casting speed, casting temperature and cooling conditions, calculating conditions causing internal defects and generated positions, and applying an electromagnetic volume force (Lorentz Force) in the casting direction in the vicinity of the positions where the internal defects are generated.

Procédé et appareil de coulée en continu, plus particulièrement de coulée en continu d'acier, qui permet d'obtenir facilement de l'acier de bonne qualité exempt de ségrégation et de porosité centrales. En d'autres termes, avec le procédé et l'appareil de la présente invention, on élimine les défauts en identifiant les conditions de solidification sur toute la zone, du ménisque (la position de surface de la partie supérieure du métal fondu) à l'extrémité du cratère (une position finale de solidification), et plus particulièrement la chute de pression de la phase liquide provoquée par le courant de phase liquide entre des dendrites induites à leur tour par la contraction de solidification dans un sens de coulée de la phase de coexistence solide-liquide sur la base des conditions de fonctionnement telles que le type (profil) des machines de coulée en continu, le type d'acier, la taille/configuration transversale d'une pièce coulée et la vitesse de coulée, la température de coulée et les conditions de refroidissement, en calculant les conditions provoquant les défauts internes et les positions générées et en appliquant une force électromagnétique sur un volume (force de Lorentz) dans le sens de coulée à proximité des positions d'apparition des défauts internes.
