摘要： The present invention relates to a hot rolling high-pressure fluid descaling method and descaling apparatus. The apparatus comprises at least one descaling unit, a axial direction of a main pipe header of the descaling unit and a rolling stock transportation direction intersect. Each nozzle ejects fluid onto a surface of the rolling stock to form an impact region. The adjacent impact regions are presented in an alternate pattern on the surface of the rolling stock. The center lines of the impact regions along a longitudinal direction are spaced apart by a specific distance, and the center lines are essentially perpendicular to the rolling stock transportation direction. The interference caused by the rebounding of the jet sprays from the adjacent nozzles is reduced. Hence, the descaling quality is improved, that is, the roll-in-scale in the surface of the products is reduced and the surface quality of the products is enhanced.
