ABSTRACT:
A submerged entry nozzle for flowing liquid metal therethrough includes a vertically disposed entrance pipe section having a generally axial symmetry and a first cross-sectional flow area. A transition area having the first cross-sectional flow area with two or more front walls and two or more side walls reduces the thickness of the first cross-sectional area by providing a convergent angle of the front walls and increases the width of the first cross-sectional area by providing a divergent angle of the side walls thereby producing a second cross-sectional area of the transition area which is generally elongated and of planar symmetry. The flow of liquid metal from the transition area is divided into two streams angularly deflected from the vertical in opposite directions.
