The invention relates to a continuous casting mold for casting molten metals, particularly steel materials, at high casting rates to form polygonal billet, bloom, and preliminary section castings (1) and the like. Said mold is comprised of a tubular mold (2) made of copper or of copper alloys whose entry cross-section (3) on the pouring-in side (4) has both a cross-section (5), which is enlarged compared to the exit cross-section (6) on the casting exit side (7), and corner radii (8). The continuous casting mold can be improved in a technologically process-oriented manner with regard to requirements concerning the cooling processes. To this end, the inner geometric cross- sectional shape (9) and the associated dimensions (10) are provided so that they are analogous to the amount of solidification heat, which is capable of being locally dissipated, at a chosen casting rate and are analogous to the extension of the tubular mold (2).
L'invention concerne une coquille de coulée continue destinée à la coulée de métaux liquides, notamment de matériaux d'acier, à des vitesses de coulée élevées, sous forme de barres de coulée polygonales (1) en billette, en bloom ou en ébauche et similaires. Ladite coquille est composée d'une coquille tubulaire (2) en cuivre ou alliage de cuivre dont la section transversale d'entrée (3), côté entrée de coulée (4), présente une augmentation de section (5) par rapport à la section transversale de sortie (6), côté sortie de barre (7), ainsi que des coins arrondis (8). L'invention vise à améliorer technologiquement ladite coquille de coulée en matière de processus de refroidissement. A cet effet, la forme géométrique (9) de la section transversale et les dimensions correspondantes (10) sont choisies en fonction de la capacité locale de dissipation de la chaleur de solidification pour une vitesse de coulée définie, et de la dilatation de la coquille tubulaire (2).
