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 () that is provided with an inlet connected, via supply channels () and a distribution chamber (), to a metal reservoir () and an outlet arranged in the mold with a support and devices for cooling the metal. In connection with the supply channels () between the metal reservoir () and the molds (), a metal lifting container () is arranged at an inlet () to the metal reservoir () via a channel () and to the distribution chamber () and the molds () via an outlet () via another channel (). The metal lifting container is sealed from the surroundings and has a connection socket () 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 () above the molds ().

Arrangement related to equipment for continuous or semi-continuous casting of metal

A method and equipment for continuous or semi-continuous casting of metal, in particular directly-cooled (DC) casting of aluminum, including at least one mold () with a mold cavity () that is provided with an inlet () linked to a metal store and an outlet with devices () for cooling the metal so that an object in the form of an extended string, rod or bar is cast through the outlet. The metal is supplied to the mold () in such a way and with such regulation that the metallostatic pressure in the contact point (solidification zone) against the mold wall is virtually zero during casting.
