Abstract (en)
Disclosed is a continuous cast method, wherein a melt (4) is supplied into a frame-shaped mould through a top opening of the mould by a nozzle (5) having at least two opposing ports (9), until a surface level (10) of the melt (4) reaches a steady state position above the ports (9), and wherein in a steady state condition, an at least superficially solidified casting (13) is drawn through a bottom opening of the mould opposite to the top opening, at a velocity corresponding to the flow rate of the melt (4), thus basically keeping the surface level (10) in the steady state position. In order to reduce spillings and related drawbacks during the starting procedure, the invention suggests that a splash shield (16) is mounted to the nozzle (5) and prevents spillings of the melt (4) protruding from the ports (9) from hitting the mould, and that the splash shield (16) is molten by the surrounding melt (4) at least in the steady state condition.
