ABSTRACT:
Iron oxide scale particles are removed from the surface of a mechanically descaled steel strand using jets of compressed air. The strand is moved along a central axis of a housing in continuous fashion through an upstream entrance opening, an entrance nozzle region, a central chamber region, an exit nozzle region and a downstream exit opening. Compressed air jets are directed into both the entrance and exit nozzle regions toward the central chamber region creating a venturi effect which draws air through the entrance and exit openings; thereby preventing dislodged scale particles from escaping into the atmosphere.
