Abstract (en)
[origin: EP1946866A1] In a hot meal casting process for copper or copper alloy sheeting of at least 20 mm thickness, molten metal is discharged from a tundish through channels (2) at a defined angle e.g. 9 degrees to the horizontal. The moving molten metal is maintained at a predefined depth (H) within the tundish. The molten metal is maintained at the same level as it passes through a distribution vessel (1) and then passes almost without delivery pressure into the channel. The molten metal then pours uncovered into a hoop mould (3) with flow maintained until reaching the required depth (7). The molten metal flow speed through the discharge channel is limited by a roughened surface or mechanical elements. Hot metal surface vortices are prevented from mould escape by a rim (13). Gases emerging from the molten metal migrate to the void (11) above the hot metal flow.
