Abstract

L'invention concerne un procédé et un dispositif pour produire des pièces de métal de dimensions déterminées, en particulier en ferro-alliages ou métaux non ferreux, à partir de la phase liquide. A cet effet, on utilise une installation de coulée en bande produisant une bande continue de métal d'épaisseur déterminée, ainsi qu'une installation de coupe qui divise la bande en pièces. Pendant la coulée et le refroidissement, un tracé de points de rupture est imprimé à la surface de la bande au moyen d'un outil de frappe (1), ce tracé déterminant les dimensions optimales prédéfinies du produit après division de la bande.
