The invention relates to a device and a method for descaling a workpiece, which is in motion in relation to the device in a movement direction (X). The device () comprises a rotor head (), which is rotatable about an axis of rotation (R), which is inclined diagonally at an angle (γ) with respect to an orthogonal on a surface () of the workpiece (). Furthermore, the device comprises multiple jet nozzles (), which are attached on the rotor head (), wherein a liquid (), in particular water, is dispensable onto the workpiece () at an angle of attack (α) inclined to the surface () of the workpiece () from the jet nozzles (). The jet nozzles () are fixedly attached on the rotor head () such that during rotation of the rotor head () about its axis of rotation (R), the spraying direction (S) of the liquid () dispensed from the jet nozzles (), with respect to a projection in a plane parallel to the surface () of the workpiece (), is aligned opposing, i.e., at a spraying angle (β) of approximately 180°, the movement direction (X) of the workpiece (). 110121014161816122012. A device () for descaling a workpiece () , preferably a hot rolled stock , in motion in a movement direction (X) in relation to the device () , comprising at least one rotor head () rotatable about an axis of rotation (R) , to which multiple jet nozzles () are attached , wherein a liquid () , in particular water , can be dispensed from the jet nozzles () onto the workpiece () at an angle of attack (α) inclined with respect to an orthogonal on a surface () of the workpiece () ,{'b': 16', '14', '14', '18', '16', '20', '12', '12', '16', '22', '14', '18', '16', '20', '12', '18', '20', '12', '22, 'characterized in that the jet nozzles () are attached to the rotor head () in such a way that during rotation of the rotor head () about its axis of rotation (R), the spraying direction (S) of the liquid () dispensed from the jet nozzles (), with respect to a projection in a plane parallel to the surface () of the ...
