Abstract

L'invention a trait au domaine de la coulée continue des métaux en fusion et notamment de l'acier. Le procédé selon l'invention consiste à soumettre le bain métallique, au sein de la lingotière, à un brassage électromagnétique, crée par un champ magnétique non stationnaire, glissant le long des parois de la lingotière dans le sens remontant jusqu'au niveau de la surface libre du métal coulé et à régler l'action de ce champ, en fonction de la profondeur désirée d (en mm) de la localisation des amas d'inclusions non métalliques à l'intérieur des produits coulés, de manière que la densité de force volumique F (en N/m** 3) agissant dans le bain métallique satisfasse à la relation F = 35 d**2 + 260 d. Le procédé selon l'invention permet de repousser à volonté les amas d'inclusions vers le centre des produits coulés jusqu'à des profondeurs prédéterminées, choisies par l'opérateur en fonction des traitements de laminage ultérieurs, de manière à obtenir à coup sûr une bonne qualité de surface de ces produits sans avoir recours à un flammage préalable. L'invention peut être appliquée à tout produit coulé en continu quels que soient sa composition ou son format.The invention relates to the field of the continuous casting of molten metals and in particular of steel. The method according to the invention consists in subjecting the metal bath, within the mold, to electromagnetic stirring, created by a non-stationary magnetic field, sliding along the walls of the mold in the direction up to the level of the free surface of the cast metal and adjust the action of this field, depending on the desired depth d (in mm) of the location of clusters of non-metallic inclusions inside the cast products, so that the density of volume force F (in N / m ** 3) acting in the metal bath satisfies the relation F = 35 d ** 2 + 260 d. The method according to the invention makes it possible to push the clusters of inclusions at will towards the center of the cast products to predetermined depths, chosen by the operator as a function of the subsequent rolling treatments, so as to undoubtedly obtain a good surface quality of these products without the need for prior flame treatment. The invention can be applied to any continuously cast product whatever its composition or format.
