- a scale scrubber which is arranged upstream of or in relation to the direction of movement upstream of a final scaffold, is generally operated at maximum pressure and volume flow for the high-pressure water. This is done for the purpose of achieving the highest possible descaling on the surfaces of the hot rolling stock.
- a disadvantage of such operation of a scale washer is the great need for energy for the production of high-pressure water.

- the hitherto known approaches for descaling workpieces are subject to the disadvantage that classification into primary and secondary scale defects and the distinction between rolled-in residual scale as a result of previously insufficient descaling and scaling down dropped during the rolling process is not feasible.
- 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 provides a device for descaling a workpiece, preferably a hot-rolled material, which is moved relative to the device in a direction of movement.
- the device comprises at least a first jet nozzle arrangement with a plurality of jet nozzles, from which a liquid, in particular water, can be applied to a surface of the workpiece under high pressure.
- the device comprises a control device and a surface inspection device that is signal-technically connected to the control device. This surface inspection device is disposed downstream of and close to the jet nozzle assembly with respect to the direction of movement of the workpiece, and enables detection of scale on the surface of the workpiece.

- the specific energy input, with which a surface of the workpiece is acted upon by the liquid discharged from the jet nozzles is controlled, preferably regulated, by means of the control device as a function of the signals of the surface inspection device.
- 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.
- the specific energy input is determined according to the present invention from the impact pressure, with which the liquid impinges on a surface of the workpiece, and the specific volume flow per width of the workpiece, ie the volume flow of the liquid sprayed onto the workpiece divided by the spray width in relation to the movement direction of the workpiece.
- the impact pressure depends on the pressure with which the liquid is supplied to the jet nozzles, the sprayed volume flow, and the distance the jet nozzles from the surface of the workpiece.
- the specific energy input is dependent on the feed rate at which the workpiece is moved in the direction of movement.
- a change in the specific energy input, as a function of the signals of the surface inspection device, can take place by adapting the abovementioned parameters, namely by means of the control device, as explained in detail below.
- the control device is program-technically set up in such a way that on the basis of the signals of the surface inspection device also a regulation of the specific energy input is possible.
- a surface quality for the workpiece can be determined and then compared with a predetermined desired value. If it is subsequently determined by means of the control device that the surface quality of the workpiece falls below the predetermined nominal value, then the specific energy input is increased. Conversely, this means that if the surface quality of the workpiece exceeds the predetermined setpoint, then the specific energy input is reduced accordingly.
- Such adjustment or adaptation of the specific energy input, based on the signals of the surface inspection device is controlled according to a preferred embodiment of the invention, d. H. by providing a corresponding control loop in the control device.
- actuators for controlling and / or regulating the specific energy input are the system pressure descaling, the height adjustment of the jet nozzles, ie the change in the distance of the jet nozzles to the surface of the workpiece, the connection / disconnection of an additional jet nozzle assembly, and the feed rate of the workpiece to disposal.
- reduction of the specific energy input namely for the case that the surface quality of the workpiece determined by the surface inspection device exceeds a predetermined setpoint, a smaller amount of high-pressure liquid is advantageously required, and thereby a reduced cooling of the workpiece is achieved.
- Such reduced cooling may be used to lower a furnace temperature or lower the energy requirement for a subsequent rolling process, ie, downstream of the jet nozzle assembly.
- reducing the temperature of the workpiece increases the final temperature of the product, allowing the product range to be extended to smaller end-uses.
- the wear of system components of the device according to the invention or of the entire descaling system is also advantageously reduced. This applies to both the jet nozzles themselves, as well as to a large extent the associated pumps and piping and all wetted parts.
- the device comprises a high-pressure pump unit signal-connected with the control device, which is in fluid communication with the jet nozzles of the jet nozzle arrangement.
- This high-pressure pump unit can be controlled by means of the control device, preferably regulated, in order to change the pressure with which the liquid is supplied to the jet nozzles.
- the descaling pressure with which the liquid impinges on a surface of the workpiece also changes correspondingly to desalt it as desired.
- the high pressure pump unit may have a plurality of individual pumps.
- the high-pressure pump unit can be equipped with at least one frequency regulator, or preferably with a plurality of frequency regulators.
- a pump or the pumps of the high-pressure pump unit is / are connected via this frequency regulator to an electrical supply network, wherein the respective frequency regulator is control technology connected to the control device. Accordingly, it is possible to control or regulate the frequency regulator of the high-pressure pump unit by means of the control device in such a way that the pressure with which the fluid is supplied to the jet nozzles of a jet nozzle arrangement is also adjusted or changed to a slight extent or with small steps, preferably also steplessly can be.
- the control device namely as a function of the signals of the surface inspection device.
- the jet nozzle assembly is mounted on a height-adjustable bracket with an actuator, wherein the actuator is connected by signal technology with the control device. If the surface quality ascertained by the control device on the basis of the signals of the surface inspection device should fall below a predetermined desired value, the distance of the jet nozzle arrangement to the surface of the workpiece can be reduced by suitable control of the actuator by means of the control device, with the result that thereby the impact pressure the liquid or the descaling pressure increases.
- the feed rate of the workpiece can be adjusted to adapt the specific energy application in accordance with the control device, if the overall process allows.
- Another advantage of the present invention is that, thanks to a reliable surface finish signal of the workpiece detected immediately downstream of the jet nozzle assembly, it is possible for the device to have only a single pair of jet nozzle assemblies, ie above and below the workpiece.
- a device according to the invention can be limited to such a pair of jet nozzle arrangements, whereby considerable investment costs for the also reduced high-pressure pump unit and associated connecting pipes can be saved. This in turn results in a space saving for the high-pressure pump unit, a reduction of the scroll and a relief of the water management, which supplies the high-pressure pump unit with liquid.
