An ingot mould has energetically cooled metal walls (1, 3) having means in their upper portion for decreasing the intensity of the heat flow extracted from the cast metal (2), such as a coating (6, 15) of a less conductive metal than that of the walls, or grooves (31) provided in said walls. On top of the walls is provided a heat insulating feeder bush (7) associated with gas injection means terminating in nozzles distributed on the inner periphery of said ingot mould. During the casting, the free surface of the liquid metal is maintained at the same level as the feeder bush, wherein the solid skin (21) only starts to solidify at the upper edge of the metal walls (3). The invention is particularly useful for the continuous casting of steel.
La lingotière comporte des parois métalliques (1, 3) énergiquement refroidies pourvues dans leur partie supérieure de moyens pour réduire l'intensité du flux thermique extrait du métal coulé (2), tels qu'un revêtement (6, 15) de métal moins conducteur que celui des parois, ou des rainures (31) réalisées dans ces parois. Ces parois sont surmontées d'une rehausse thermiquement isolante (7) associée à des moyens d'injection d'un gaz débouchant en jets répartis sur le pourtour intérieur de la lingotière. Lors de la coulée, la surface libre du métal liquide est maintenue au niveau de cette rehausse, le début de solidification de la peau solide (21) commençant seulement au niveau du bord supérieur des parois métalliques (3). Application notamment à la coulée continue de l'acier.
