  • Patent number: 6260603
    Abstract: A method for automatic, vertical continuous casting of metals, in particular aluminium alloys, in a casting facility having several molds. According to the method, the liquid metal is fed from a furnace along a spout to the molds and guided, via nozzles with adjustable through-flow, to the molds which are initially closed off by the dummy blocks arranged on a lowerable casting table. The metal through-flow volume of each nozzle is adjusted individually for each mold on the basis of an initial time (t0) and an initial metal level (N0) at which adjustment of the metal level begins, in such a way that the metal in all molds at a pre-set starting time (tS) is at substantially the same starting level (NS) at which the casting table starts being lowered for the production of the metal strands.
