Patent CA-2277959-A1 (CA)
Inventor: VUIGNIER ERIC
IPC: B22D11/16
Filed: 1998-01-07
Abstract: The invention relates to a method for automatic, vertical continuous casting of metals, in particular aluminium alloys, in a casting facility comprising several moulds.  According to the said method, the liquid metal is fed from a furnace along a spout to the moulds and guided, via nozzles with adjustable through-flow, to the moulds 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 mould 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 moulds at a pre-set starting time (t S) is at substantially the same starting level (N S) at which the casting table starts being lowered for the production of the metal strands. The metal level (N) is adjusted simultaneously during filling between the initial level (N0) at the initial time (t0) and the starting level (N S) at the starting time (t S) in all moulds on the basis of time (t) in accordance with a set-point curve N = f(t) which is identical for all moulds. The slope dN/dt of the set-point curve is greater in a range (A) starting from the initial level (N0) and smaller in a range (B) in relation to the starting level (N S) than the mean slope (N S - N0)/(t S-t0) between the initial and the starting level.
