摘要：
A submerged entry nozzle (10) for introducing molten steel into a casting mold is disclosed. The nozzle includes a nozzle structure defining a central bore (16) and two transverse exit ports (20a, 20b) communicating with the bottom of the central bore, the central bore terminating at an upwardly dish-shaped bottom surface (18) that extends to the periphery of the nozzle structure and forms the lower surface regions (23a, 23b) of the exit ports, whereby molten steel flowing across the upwardly dish-shaped bottom surface is directed outwardly and upwardly from the nozzle structure.
