Equipment for continuous, horizontal casting of metal, in particular aluminium, the equipment including an insulated reservoir or pool (2), which is designed to contain liquid metal, and a releasably attached mould (3), which can be removed from the pool (2), with an insulating plate (19) with holes (25, 26) which communicate with the mould, the mould (3) including a preferably circular mould cavity (17) with a wall (12, 13) of permeable material for the supply of oil and gas. The wall provides primary cooling to the metal being cast and at least one slit or nozzles (16) arranged along the circumference of the cavity for the direct supply of coolant, providing secondary cooling at the metal. The primary cooling is so designed that it may be increased or reduced. That the insulating plate (19) is replaceable and, depending on the type of alloy and the cooling required, is designed to extend along the permeable material (12, 13) (at 24) in the cavity (17).
Equipement servant au coulage horizontal continu de métal, en particulier d'aluminium, et comprenant un réservoir isolé (2) conçu pour contenir du métal liquide et un moule (3) fixé amovible qu'on peut retirer du réservoir et qui comporte une plaque isolante (19) pourvue d'orifices (25, 26) communiquant avec le moule (3), ce dernier présentant une cavité (17), de préférence, circulaire possédant une paroi (12, 13) en matériau perméable pour l'alimentation en huile et en gaz. Cette paroi assure un premier refroidissement au métal en cours de coulée et au moins une fente ou des ajutages (16) situés le long de la circonférence de la cavité permettent d'effectuer une alimentation directe en réfrigérant, ce qui assure un deuxième refroidissement au métal. Il est possible d'augmenter ou de diminuer le premier refroidissement. On peut remplacer la plaque isolante (19) et, en fonction du type d'alliage et du refroidissement nécessaire, il est possible de l'étendre le long du matériau perméable (12, 13) (à 24) de la cavité (17).
