1. A method for extruding molten metals, in particular alloys with a relatively high melting point, e.g. steel, wherein the molten metal is conveyed via at least one melt feed line (2), e.g. a duct, from a melt container (1), a pan or the like, to a substantially horizontally arranged chill (4) connected with the container in a fluid-tight manner and preferably fluid-cooled, through an outlet opening of a nozzle block (3), which opening has a smaller cross-sectional area than the chill (4), and the billet is drawn backwards out of the chill (4), preferably stepwise, possibly with a partial step, characterised in that the melt is conveyed substantially tangentially into a substantially horizontal part (8, 10) of the melt feed line (2), thus effecting rotation of the melt around the longitudinal axis (12) of the part (8), and thereafter the rotating melt is conveyed into the chill (4). |
