<p>The invention relates to a casting nozzle with diamond-shaped internal geometry, to a casting nozzle with a plurality of orifices and to a process for flowing a liquid metal therethrough. According to the invention, the casting nozzle includes an elongate bore having at least one upper exit port (182) and at least a lower exit port (176). A baffle (178) is positioned in the proximity of the upper exit port (182) to divide the liquid metal flow through the bore into at least one outer stream and a central stream, the outer stream flowing through the lower exit port (176). The claimed process provides for the liquid metal flow through the casting nozzle while dividing the flow between the outer stream and the central stream, so that the effective discharge angle of the outer stream exiting through the upper exit port varies based on the flow rate of the liquid metal through the casting nozzle.</p> |
