Definitions
- the invention has for its object to optimize the descaling of workpieces in terms of surface quality, while also reducing the need for energy and high-pressure liquid to a required minimum.
- This object is achieved by a device for descaling a workpiece having the features specified in claim 1, and by a method according to claim 10.
- Advantageous developments of the invention are defined in the dependent claims.
- the invention is based on the essential finding that a surface inspection device is arranged close to the location of the jet nozzle arrangement.
- the feature "near-field" in the sense of the present invention means that the surface inspection means is positioned downstream of the jet nozzle assembly and immediately adjacent thereto with respect to the direction of movement of the workpiece past the jet nozzle assembly at a feed rate , This makes it possible to monitor the result of exposure to the surfaces of the workpiece with a liquid under high pressure and the resulting Entzu matterss- quality and possibly influence, in particular before the workpiece further production steps such. B. undergoes further rolling operations.
- a device 10 according to the invention has a jet nozzle arrangement with a plurality of jet nozzles, from which a liquid, in particular water, is sprayed onto a surface of a workpiece under high pressure.
- the jet nozzle arrangement can be formed from a rotor head rotatable about an axis of rotation (FIG. 1) or from a spray bar (FIG. 2), as explained in detail below.
- jet nozzles 16 are provided from which a liquid 18 (symbolized in simplified dashed lines in FIG. 1) is sprayed under high pressure onto a surface 20 of the workpiece 12 in order to descalate the workpiece 12 suitably.
- FIG. 1 a liquid 18 (symbolized in simplified dashed lines in FIG. 1) is sprayed under high pressure onto a surface 20 of the workpiece 12 in order to descalate the workpiece 12 suitably.
- control device 22 the high-pressure pump unit 24 and the surface inspection device 26 the same contexts apply to the embodiment of FIG. 2 as for the embodiment of FIG. 1, these technical components not being shown in FIG. 2 for the sake of simplicity.
- the descaling quality is continuously monitored by the surface inspection device 26. This can be close to the location and immediately adjacent to a jet nozzle arrangement, for. Example, in the form of a rotor module pair or a spray bar pair 38, be determined whether the desired surface quality for the workpiece 12 reaches a predetermined target value. If this is not the case, then by a suitable control of the high-pressure pump unit 24 and the / provided for this frequency regulator / s 25 by means of the control device 22, the pressure with which the liquid 18 is supplied to the jet nozzles 16, wherein, if necessary, also a further pump of the high-pressure pump unit 24 is switched on.
