ABSTRACT:
Apparatus for removing surface layers from workpieces, especially for descaling hot rolled stock moved with respect to the apparatus, by spraying highly pressurized fluid, especially pressurized water on both sides of the rolled stock from rows of nozzles extending across the workpiece width and each including a plurality of nozzle heads is characterized in that the nozzle heads rotate and each nozzle head comprises at least one nozzle, preferably a plurality of nozzles uniformly distributed around its circumference. The number of nozzles, the rotary speed of the nozzle heads, and the speed of relative motion between the rolled stock and the apparatus are tuned such that desired average intensity and depth of removal are obtained.
