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 liquid inlet defined by an upstream strainer and a downstream high impact attachment tube for accelerating liquid flow. A one-piece multi-stage liquid straightening vane segment is disposed within a central liquid flow passage of the nozzle assembly for more effectively reducing liquid turbulence of the high pressure liquid flow with resultant improved control in the tightness of the thin, flat spray panner. The one-piece vane segment further is adapted for efficient assembly and replacement in the spray nozzle assembly without the need for handling and precise alignment of a plurality of individual vane elements.
