ABSTRACT:
A spray nozzle assembly for directing thin, straight line, high pressure liquid spray onto moving steel slabs for penetrating and removing scale buildup in steel processing operations. The spray nozzle assembly includes a high impact attachment tube for accelerating liquid flow, a tungsten carbide spray tip at a discharge end of the high impact attachment tube for directing a flat spray pattern, an inlet defined by a strainer at an upstream end of the high impact attachment tube, and a staged vane section intermediate the inlet and spray tip for reducing liquid turbulence in the flow passageway. The vane section comprises a pair of axially spaced vanes each having a plurality of radial vane elements that define a plurality of laminar flow passageways, with the laminar flow passageways of one vane being circumferentially offset to the laminar flow passageways of the other vane.
