Abstract

The invention relates to a device and a method for descaling a workpiece that is in motion relative to the device in a movement direction (X). The device (10) comprises a rotor head (14) which can rotate about an axis of rotation (R) that is tilted, at an angle (Gamma), at an incline with respect to an orthogonal line to a surface (20) of the workpiece (12). The device also comprises a plurality of jet nozzles (16) mounted on the rotor head (14), wherein a liquid (18), particularly water, can be emitted from the jet nozzles (16) onto the workpiece (12) at an angle of incidence (ALPHA) at an incline to the surface (20) of said workpiece (12). The jet nozzles (16) are mounted rigidly on the rotor head (14) such that, when said rotor head (14) rotates about its axis of rotation (R), the spraydirection (S) of the liquid (18) emitted from the jet nozzles (16) is directed counter relative to a projection into a plane parallel to the surface (20) of the workpiece (12), i.e. at a spray angle(Beta) of approximately 180 DEG to the movement direction (X) of the workpiece (12).

Description

technical field [0001] The invention relates to a device and a method for descaling workpieces which are moved in a direction of motion relative to the device. The workpiece is in particular a hot-rolled workpiece. Background technique [0002] It is known from the prior art to spray water at high pressure onto the surface of the workpiece in order to descale workpieces, in particular hot-rolled workpieces. In order to descale the workpiece surface flawlessly, high-pressure water jets are usually sprayed from multiple nozzles of the descaler. In this context, descalers in hot rolling plants are components which are designed to descale, ie to remove impurities consisting of iron oxide from the surface of the rolling stock. [0003] WO 2005 / 082 555 A1 discloses a descaler with which scales are removed from a rolling stock moving relative to the descaler by means of jets of high-pressure water jets. The descaler comprises at least one row of nozzle heads across the width of ...
