Abstract
A device in connection with equipment for continuous or semi-continuous casting of metal, in particular direct mold (DC) casting of aluminum in the form of a billet or wire billet. The device includes a mold with a cavity or a mold (3) that is provided with an inlet connected, via supply channels (6, 18) and a distribution chamber (5), to a metal reservoir (13) and an outlet arranged in the mold with a support and devices for cooling the metal. In connection with the supply channels (6, 18) between the metal reservoir (13) and the molds (3), a metal lifting container (15) is arranged at an inlet (16) to the metal reservoir (13) via a channel (18) and to the distribution chamber (5) and the molds (3) via an outlet (17) via another channel (6). The metal lifting container is sealed from the surroundings and has a connection socket (19) for connection to a vacuum source so that, when a casting operation starts, metal is sucked into the metal lifting container and lifted to a level that is higher than the level of the distribution chamber (5) above the molds (3).
