A method and apparatus for flowing liquid metal through a casting nozzle includes an elongated bore having at least one entry port, at least one upper exit port, and at least one lower exit port. A baffle is positioned proximate to the upper exit port to divide the flow of liquid metal through the bore into at least one outer stream and a central stream, the outer stream flowing through the upper exit port and the central stream flowing past the baffle and toward the lower exit port. The baffle is adapted to allocate the proportion of liquid metal divided 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 throughput of liquid metal through the casting nozzle.
