ABSTRACT:
The present invention provides an improved submerged entry nozzle (SEN) for use in a continuous casting machine. The SEN includes a connection end adapted to attach to a slide gate mechanism, a discharge end including a bifurcated port, a tapered bore extending between the connection end and the discharge end, and a flow control structure positioned within the discharge end. The flow control structure includes divergent flow control surfaces extending downward along opposite sides of a contiguous edge, each downwardly extending divergent flow control surface flaring in an outward direction toward a respective perimeter defining an outside edge of the bifurcated port and communicating therewith.
