Abstract

Procédé pour couler en continu en succession différentes qualités d'acier, dans lequel on coule une première qualité d'acier puis une deuxième qualité d'acier dont la composition chimique est différente de celle de la première. On arrête la coulée de la premiere qualité d'acier liquide dans le moule, on immerge un corps de refroidissement sensiblement dans la partie centrale de la première qualité d'acier dans le moule, on forme autour de ce corps de refroidissement une couche solidifiée se raccordant à une coque solidifiée développée à partir de la paroi du moule et on verse la deuxième qualité d'acier liquide dans le moule avant que la surface de la première qualité d'acier liquide au-dessus du corps de refroidissement ne soit solidifiée.A process for continuously casting different grades of steel in succession, in which a first grade of steel is cast and then a second grade of steel, the chemical composition of which is different from that of the first. The casting of the first grade of molten steel in the mold is stopped, a cooling body is immersed substantially in the central part of the first grade of steel in the mold, a solidified layer is formed around this cooling body. connecting to a solidified shell developed from the wall of the mold, and the second grade of molten steel is poured into the mold before the surface of the first grade of molten steel above the cooling body is solidified.
