CA 2253873

A liquid-cooled ingot mould for continuously casting thin steel plates has two side walls (2) opposite each other, a copper plate (8) and a steel support plate (9). The copper plates (8) which delimit the mould cavity (4) are detachably connected to the support plates (9) by metal bolts (12) made of a CuNiMnFe alloy. The metal bolts (12) are welded to the copper plates (8) using a nickel ring (13) as welding filler material. Channels for coolant (10) are provided in the copper plates (8) and cooling bores (11) are provided in the area of the cross sectional plane (QE) of the metal bolts (12).

Coquille à refroidissement par un liquide, pour la coulée continue de brames d'acier minces, présentant deux parois latérales larges (2) composées chacune d'une plaque en cuivre (8) et d'une plaque support en acier (9). Les plaques en cuivre (8) délimitant une cavité de moulage (4) sont fixées amovibles sur les plaques supports (9) au moyen de boulons (12) en alliage CuNiMnFe. Les boulons (12) sont soudés aux plaques en cuivre (8) en utilisant complémentairement une bague en nickel (13) comme métal d'apport. Des canaux de refroidissement (10) sont ménagés dans les plaques de cuivre (8), des trous de refroidissement (11) étant par ailleurs prévus dans la zone des plans transversaux (QE) des boulons (12).
