A process for the continuous casting of the metal is disclosed, in particular of steel, for producing billets and blooms with a polygonal or approximately round cross-section. In order to improve chilling within the mould, thus achieving a better casting quality, and to optimize the casting process in the case of various operations, steels is introduced in a mould (3) with a cross-section at the pouring side that has sections (2) with bulges (9) distributed around the circumference of the mould cavity (6). The bulging skin that is created in the mould (3) is formed along at least a partial length of the mould (3). The extent of bulge elimination (9) is determined by setting a corresponding level of the bath within said partial length of the mould (3) as a function of the casting parameters.
L'invention concerne un procédé de coulée continue de métal, notamment d'acier, pour la production de billettes et de blooms, de section polygonale ou presque ronde. Afin d'obtenir un meilleur refroidissement à l'intérieur de la coquille et par conséquent une meilleure qualité de coulée et afin d'optimiser le procédé de coulée lors de diverses opérations, l'acier est introduit dans une coquille (3) dont la section transversale, côté coulée, comporte des sections (2) munies de bosses (9), qui sont reparties autour du creux du moule (6), La croute bombée qui se forme dans la coquille (3) est formée sur au moins une partie de la longueur de la coquille (3). En outre, la proportion de redressage de la bosse (9) est définie par détermination d'un niveau de bain approprié, pour la partie de la longueur concernée de la coquille (3), en fonction des paramètres de coulée.
