Title of Invention

AN AIR ASSISTED SPRAY NOZZLE

Abstract An air assisted spray nozzle assembly, having particular utility in spraying liquid coolants in continuous metal casting systems, which is adapted for operation with substantially reduced air consumption. The nozzle body includes a pre- atomizing unit that has a relatively small sized pressurized air inlet, a liquid impingement post with a uniquely configured impingement face for enhancing liquid breakdown and intermixing with a pressurized air stream from the air inlet, and an expansion chamber configured to reduce eddy currents that detract from efficient pre- atomization of the liquid. The spray nozzle further includes an elongated spray tip supporting barrel adapted for releasable mounting in the pre-atomizing head in predetennined rotational orientation relative to its longitudinal axis for properly receiving and supporting a removable spray tip.
