Embodiment Construction

[0031] Refer below Figure 1 to Figure 6 Various embodiments of the present invention will be described in detail. In the drawings, the same technical features are correspondingly denoted by the same reference numerals. Furthermore, it should be pointed out that the representation in the drawings is basically simplified and in particular not shown to scale. In some of the figures, a Cartesian coordinate system is drawn in order to spatially orient the device according to the invention with reference to the workpiece to be descaled and moved.

[0032] The device 10 according to the invention is used for descaling a workpiece 12 which is moved relative to the device 10 in the direction of movement X. FIG. The workpiece may be a hot rolled piece of the moving bypass device 10 .

[0033] The device 10 according to the invention has a jet nozzle assembly with a plurality of jet nozzles from which a liquid, in particular water, is ejected at high pressure onto the surface of the ...

Abstract

The invention relates to a device and a method for descaling a workpiece that moves in relation to the device in a direction of movement. The device comprises a rotor head (14) that can rotate about an axis of rotation (R) that is obliquely inclined at an angle in relation to an orthogonal line to a surface of the workpiece. The device also comprises a plurality of jet nozzles (16.1; 16.2; 16.3) mounted on the rotor head (14), wherein a liquid, particularly water, can be emitted from the jet nozzles (16) onto the workpiece at an angle of incidence obliquely to the surface of said workpiece. The plurality of jet nozzles (16.1; 16.2;16.3) is mounted on the rotor head (14) at a radial distance (s1 ; s2; s3) of different lengths from the axis of rotation (R) thereof, wherein a larger volume flow (V1; V2; V3) of liquid is emitted from a jet nozzle (16.1; 16.2; 16.3) that is at a larger radial distance from the axis of rotation (R) than a jet nozzle that is at a shorter radial distance fromthe axis of rotation (R).

Description

technical field [0001] The invention relates to a device and a method for descaling a workpiece which is moved relative to the device in a direction of movement. 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 connection, what is called a descaler in a hot rolling plant is a component which is arranged to remove scale, ie to remove impurities consisting of iron oxide, from the surface of the rolling stock. [0003] WO 2005 / 082555 A1 discloses a descaler with which a rolling stock moving relative to the descaler is descaled by means of jets of high-pressure water jets. The descaler includes at least one row of nozzle heads across ...
