A device for continuous or semi-continuous casting of metal comprising a cooled mold (22) and an induction coil (10) arranged at the top end of the mold. The mold comprises in its top end a plurality of hollow, old segments (22a, 22b, 22c, 22d, 22e, 22f, 22'b, 22'c, 22'd) separated from each other by partitions (26a, 26b, 26c, 26d, 26e), which all comprise an electrically insulating barrier. Both the mold segments and the partitions are oriented essentially in the casting direction. Each hollow top end mold segment comprises a core of a mechanically supporting bar or beam (25a, 25b, 25c, 25d, 25e, 25f, 25'a, 25'b, 25'c, 25'd, 25'e, 25'f) arranged within the hollow mold segment such that it is surrounded by the hollow mold segment. The core exhibits superior mechanical properties in relation to the mold.
On décrit un dispositif de coulée continue ou semi-continue de métaux, qui comprend un moule refroidi (22) et une bobine d'induction (10) disposée au sommet du moule. Le moule comprend, à son extrémité supérieure, une pluralité de segments du moule (22a, 22b, 22c, 22d, 22e, 22f, 22'b, 22'c, 22'd) séparés les uns des autres par des cloisons (26a, 26b, 26c, 26d, 26e) toutes munies d'une barrière isolante. Tant les segments du moule que les cloisons sont essentiellement orientés dans le sens de la coulée. Chaque segment du moule creux de l'extrémité supérieure comprend un coeur de barre ou de poutre de soutien mécanique (25a, 25b, 25c, 25d, 25e, 25f, 25'a, 25'b, 25'c, 25'd, 25'e, 25'f) disposé à l'intérieur du segment du moule creux et encadré par ce dernier. Le coeur présente des propriétés mécaniques supérieures en relation avec le moule.
