<p>A spray nozzle (12) particularly useful for directing a liquid coolant onto continously cast metal shapes. The spray nozzle (12) includes a nozzle body (18) having a liquid flow passageway (21) communicating with a discharge orifice (22) and a vane (30) disposed within the passageway (21) upstream of the discharge orifice (22). The vane (30) has a central orifice (35) for creating an axial flow stream and a plurality of circumferentially spaced angled passages (36) for tangentially directing a plurality of liquid flow streams which create liquid turbulence, breakdown and intermixing with axial flow stream such that liquid emitted from the discharge orifice (22) is adapted for more uniform cooling of a cast metal notwithstanding changes in liquid pressure commensurate with changes in the rate at which the metal is cast.</p> |
