- a steel strip or a non-ferrous non-ferrous metal strip as a steel strip or a non-ferrous non-ferrous metal strip.
- a bending force measuring element allows a substantially more precise evaluation of the deflection of a work roll, since the bending force actually acting on the work roll is measured and not a supposed bending force determined by conversion of the hydraulic pressure which is not immediately in effective bending due to hysteresis can implement.
- the bending force measuring element is installed as a replacement for a bolt in the eye of an eyelet of the formed as a piston-cylinder unit bending device.
- the bending force measuring element with the eyelet then forms the end of the piston-cylinder unit associated with the work roll or the chocks of the work roll, while its other end is connected to the roll stand.
- the bending force measuring element is installed axially parallel or coaxially in the work roll, preferably in its journal. For this purpose, a separate hole is required.

- the invention relates to a roll stand for rolling a rolled strip of metal, preferably of steel or of a non-ferrous metal.
- the rolling stand comprises two roll stands, one on the operating side and one on the drive side of the roll stand. Between the roll stands two work rolls and two each of the work rolls associated support rollers are rotatably mounted in chocks.
- the back-up rolls can be lifted vertically from their respective work rolls by means of hydraulic cylinders (see reference numeral 19 in Figure 1); the rolling stand is then in the so-called. Passed skimming operation.
- the work rolls 7, 8 are respectively moved via bending devices 11 associated therewith in the form of hydraulic cylinders, vertically to the direction of passage of the rolled strip.
- the hydraulic cylinders 11 are connected at their stator-side end via bending blocks 13 fixed to the respective bars 2 of the stand.
- the bending devices 11 act on guide frames 16, 17 and chocks 6 directly the stored in the chocks work rolls 7, 8, in order to move or bend.
- the hydraulic cylinders of the bending devices 11 are in the form of an eyelet 12 with an eye, in which case via a bolt 30 an articulated connection with the guide frame 16, 17 and thus indirectly with the work rolls 7, 8 is produced.
- this bolt is replaced by a bending force measuring element 30 in order to be able to determine precisely the bending force actually acting on the work roll; This is particularly important if a part of the cylinder pressure can not convert into effective bending force due to particular hysteresis due to friction.
- a drive device 20 is provided for driving the bending devices 11.
- the bending force measuring element 30 can also be installed directly in the work rolls 7, 8, then axially or ideally coaxially with the center line of the respective work rolls, preferably in their tenons.
- both the drive side AS and the operating side BS of the roll stand are represented by two bending devices or hydraulic cylinders 11, which each represent a spar of a roll stand. Between two bars or between the two bending devices 11, the bending force measuring element 30 of the corresponding roll stand is shown in each case.
- Figure 2 shows a first embodiment for an application of the direct bending force measurement according to the invention in the individual uprights of the rolling stand. It is shown a separate bending force control both for the drive side AS as well as for the operating side BS of the rolling mill 100.
- the actual bending force values determined by the two bending force measuring elements 30 per side AS, BS are preferably averaged before they enter the control as actual bending force.
- a comparison between a predetermined Soii-bending force and the averaged actual bending force for determining a control deviation and subsequently this determined control deviation serves as a control variable for an actuator in the form of a servo valve 50 for a purely force-controlled control of the bending devices 11.
- the control of the bending devices 11 takes place on the drive side AS and the operating side BS of the rolling mill respectively, ie all bending devices 11 on the drive side AS receive the same drive signals in accordance with the measured on the drive side control deviation and all Bending devices 11 on the operating side BS receive the same control signals in accordance with the control deviation measured on the operating side.
- Figure 3 shows an alternative second embodiment, wherein only a common control circuit for the drive side AS and the operating side BS of the rolling mill 100 is provided.
- the first embodiment not only the bending forces on the drive or the operating side, but the measured actual bending forces are averaged from both sides of the roll stand to a control input.
- the determination of a control deviation and the activation of a servo valve 50 is again carried out so that it carries out a symmetrical control of all operating devices 11 of the rolling mill stand.
- FIG. 4 shows a third exemplary embodiment, wherein the bending force measuring element 30 according to the invention provides actual bending force values for each individual wafer stand, and wherein these measured values are respectively provided in a bending stand 11 or for its associated bending devices 11. Hene control input.
- the individual control of the individual roll stands shown in Figure 4 are particularly well suited for locating errors in the bending devices of a roll stand, when z. B. is determined that a predetermined desired bending force value by the control device 20 'can not be permanently adjusted and achieved, but if a constant deviation remains non-zero permanently.
- Figure 5 shows a combined bending force-cylinder position control, separated by way of example for the drive side and the operating side of the rolling mill 100.
- an evaluation of the actual positions of the hydraulic cylinders of the bending devices 11 determined by position sensors 14 takes place per side in each case separately in addition to the evaluation of the bending force.
- the measured actual positions of all cylinders are averaged per side and fed to a position-target-actual comparison within the control device 20 '.
- the result of this comparison is a control deviation e p with respect to the average position of the cylinders.
- a control deviation e k in relation to the average bending force per side is determined analogously to FIG.
- Figure 6 shows an advantageous application example of such a combined bending force position control, namely in the form of a roughness control.
- the roughness of the rolled strip 200 to be rolled is determined on its surface with the aid of a roughness detector Ra in which it travels along a measuring track over the rolled strip.
- the roughness detector Ra provides a measurement signal Ist-Ra representing this actual roughness of the strip after the rolling process.
- the control devices 20 'for the drive side AS and the operating side BS of this measurement signal is in each case with a predetermined desired roughness compared to adjust the position or the bending force of the corresponding work roll in accordance with the roughness deviation resulting from this comparison. This is done in particular during a temper rolling operation of the roll stand, ie in which the support roll is lifted off the work roll in each case.
- the work roll press with a certain force everywhere on the surface of the rolled strip. This means that, in order to realize the desired roughness on the surface of the rolled strip, bending force-based regulation of the bending devices 11 is to be provided in principle, which ensures that, given a predetermined thickness of the rolled strip, the work roll always has the required constant bending force or rolling force whose surface acts.
- this can be done in such a way that, if the force acting on the rolled strip falls below a predetermined threshold, because the rolled strip has a locally thinner area than the predetermined thickness, the position of the work roll in the context of the subordinate position control to the reduced Thickness of the rolled strip can be adjusted. Concretely, then z. B. the upper work roll are lowered so far that the force acting on the rolled strip bending force or rolling force again exceeds the predetermined lower threshold and thus the required roughness can be realized.
- FIG. 6 shows a mode of operation for the waiter assembly which is alternative to the regulation, namely a control operation in which the activation means 20 is designed in the form of a control means 20 ".
- This control operation is suitable both for carrying out a rolling operation and for carrying out a test of Bending devices 11 with regard to their proper functioning.
- control device 20 in the form of the control device 20 "gives, for example, a desired bending force signal to the work roll, whereby in principle - unlike a control - no control takes place, whether a desired set bending force also actually realized at any time of rolling.
- a test of the individual bending devices can be carried out with the aid of the control device 20 "simply in such a way that the control device 20" outputs a signal B-SoII, which represents the desired bending force, to the bending device 11, and then that in the following Work roll set bending force using the bending force measuring element 30 is detected.
- the bending force detected by the measuring element 30 is then subsequently compared in an evaluation device 40 with the originally specified desired bending force B-SoII.
- a deviation between the desired bending force and the actual bending force B-Ist determined in this comparison can then be interpreted as an increased wear of either the bending blocks 13, the cylinders or the rods of the bending devices 11 or the bending frames 16 and 17, respectively, and to a Control center.
- FIG. 8 shows a predetermined desired hysteresis for a single bending device 11.
- the hysteresis represented hatched represents an allowable tolerance range for the relationship between force F and path S in a bending device 11.
- the control device 20 "just described with reference to FIG. 7 advantageously enables the simultaneous presetting of a desired path and a desired force and the downstream evaluation device 40 makes it possible to compare these preset desired values with actually measured bending forces and traveled paths for a single bending device 11 If it is then determined in this comparison that a value pair of actual path S1 and associated measured actual bending force F1 determined for this bending device lies outside the hatched desired hysteresis, this indicates a malfunction of the bending device 11. Conversely, the position leaves of a pair of values S2 / F2 within the desired hysteresis on a proper function of the bending device 11 infer.
- the separate detection of the bending force by the bending force measuring element 30 provided according to the invention is preferably used in cold rolling mills. Not only are cold rolling mills for steel in question, but also cold rolling mills for non-ferrous metals, aluminum, copper or copper alloys.
