Abstract: Equipment for the semi-continuous direct chill (DC) casting of sheet ingot or slabs of different dimensions, in particular for rolling purposes, including a mold frame (2) with a pair of facing long side walls (3) and a pair of facing short end walls (4). The walls of the mold define an upwardly open inlet for the supply of metal and a downwardly facing outlet provided with a starter block (5) on a movable support which prior to each casting closes the opening. The equipment includes a device for changing the mold dimensions where at least one end wall can be displaced to enable casting of ingots with different sizes, and it further includes a device for indirect and direct cooling of the metal during casting. The equipment also includes apparatus for flexing the long side walls (3) of the mold, thereby enabling adjustment of the flexible middle part of the long side walls (3) inwardly or outwardly to adapt to the desired sheet ingot size, the desired casting speed and/or alloy composition.

Abstract: Metal filling equipment for continuous casting mould/s, in particular mould/s for the semi-continuous direct chill (DC) casting of aluminium sheet ingot or slabs of different dimensions, in particular ingot or slabs for rolling thin aluminium sheet or strips. The equipment includes a closed metal filling box or container (10) provided above the mould/s (2). The box receives metal from a holding furnace (not shown) through a launder or metal transfer channel (11 ). The metal flow to the box is controlled by means of a valve device (16), whereby the metal filling box is provided with air evacuating means (20) to obtain elevated metal level inside the box during casting. Metal distributor outlets in the form of insulated pipe stubs (18) are provided for each mould, protruding downwardly from the bottom of the metal filling box (10). With the described metal filling box is obtained improved metal distribution and even metal temperature across the mould/s.

Abstract: A device in connection with equipment for continuous or semi-continuous casting of metal, in particular direct mould (DC) casting of aluminium in the form of a billet or wire billet, comprising a mould with a cavity or mould (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 mould with a support and devices for cooling the metal. In connection with the supply channels (6, 18) between the metal reservoir (13) and the moulds (3), a metal lifting container (15) is arranged that is connected at an inlet (16) to the metal reservoir (13) via a channel (18) and to the distribution chamber (5) and the moulds (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 designed to be sucked into the metal lifting container and lifted to a level that is higher than the level of the distribution chamber (5) above the moulds (3).
