Abstract
A nozzle head for descaling rolling stock, said rolling stock moving relative to said nozzle head, is adapted to be mounted for rotation about an axis of rotation relative to a surface of said rolling stock. Said nozzle head comprises a plurality of nozzles adapted to spray a liquid on said rolling stock, wherein said nozzles are positioned at different radial distances from said axis of rotation.
Claims14
A nozzle head for descaling rolling stock moving relative to said nozzle head;
- wherein said nozzle head is adapted to be mounted for rotation about an axis of rotation relative to a surface of said rolling stock;
- wherein said nozzle head comprises a plurality of nozzles adapted to spray a liquid on said rolling stock;
- and
- wherein said nozzle head comprises a first group of at least three of said nozzles positioned at a first radial distance from said axis of rotation, and a second group of at least two of said nozzles positioned at a second radial distance from said axis of rotation, wherein said second radial distance is smaller than said first radial distance;
- and
- wherein a number of nozzles in said second group of said nozzles is smaller than a number of nozzles in said first group of said nozzles.
A device for descaling rolling stock, the device comprising a plurality of nozzle heads, each of the plurality of nozzle heads being adapted to be mounted for rotation about an axis of rotation relative to a surface of said rolling stock;
- wherein each said nozzle head comprises a plurality of nozzles adapted to spray a liquid on said rolling stock;
- and
- wherein each said nozzle head comprises a first group of at least three of said nozzles positioned at a first radial distance from said axis of rotation, and a second group of at least two of said nozzles positioned at a second radial distance from said axis of rotation, wherein said second radial distance is smaller than said first radial distance;
- wherein a number of nozzles in said second group of said nozzles is smaller than a number of nozzles in said first group of said nozzles;
- and
- wherein the plurality of nozzle heads is arranged vertically and/or horizontally across a width of said rolling stock, and/or arranged circularly across said rolling stock.
A method for descaling rolling stock, comprising:
- rotating a nozzle head about an axis of rotation relative to a surface of said rolling stock, said nozzle head comprising a plurality of nozzles;
- and
- spraying a pressurized liquid on said rolling stock from said nozzles;
- wherein said nozzle head comprises a first group of at least three of said nozzles positioned at a first radial distance from said axis of rotation, and a second group of at least two of said nozzles positioned at a second radial distance from said axis of rotation, wherein said second radial distance is smaller than said first radial distance;
- and
- wherein a number of nozzles in said second group of said nozzles is smaller than a number of nozzles in said first group of said nozzles.
