Full cone air assisted spray nozzle for continuous metal casting cooling

A full cone liquid spray nozzle comprising:

• a nozzle body having a discharge orifice at a downstream end and an inlet at an upstream end for connection to a liquid supply, a liquid flow passageway extending through the nozzle body communicating between the inlet and the discharge orifice;
• a vane having an outer perimeter disposed in fixed engaging relation with the nozzle body liquid flow passageway upstream of the discharge orifice, said vane having a plurality of V-shaped passageways therein extending through the outer perimeter of the vane between an upstream face and downstream face of the vane;
• a whirl and mixing chamber defined by the liquid flow passageway between the vane and the discharge orifice;
• said V-shaped passageways each having a pair of opposed sidewalls at an acute angle to each other that define a straight line apex at an angle to and in a different plane than the longitudinal axis of the vane, said opposed side walls of each V-shaped passageway extending from the straight line apex of the passageway to an outer perimeter of the downstream face of the vane,
• said V-shaped passageways intersecting the downstream face of the vane at a position offset from an axial center of the vane so as to form a solid generally circular end face surface that is defined by a circle through the apexes of the V-shaped passageways and a plurality of surface area legs that extend outward from the circular end face surface when viewed towards the downstream face of the vane, and said surface area legs having a radial length greater than the radius of said circular end face surface defined by the apexes.

• said vane including an upstream cylindrical section that defines said upstream end face and a downstream frustoconical section that defines said downstream end face, and
• said frustoconical section being disposed within a cylindrical section of said liquid passageway with a tapered side of the frustoconical sections extending inwardly in spaced relation from said cylindrical section in a downstream direction.
