Definitions
- the invention relates to a rolling stand with at least one roller having an axis of rotation, which is mounted in two in the axial end regions of the roller arranged and each having a center plane having chocks, said roller employed with at least one adjusting element in the direction perpendicular to the conveying direction of the rolling stock can be.
- DE 24 28 823 A1 uses a spindle system with which a bending moment can be applied to the two roll chocks by displacing the spindle onto two shell-shaped shell elements. As a result, a bending moment is introduced into the roll chocks, which counteracts the bending moment caused by the deflection of the roll.
- a toggle-type linkage is used in order to exert a bending moment on the two chocks of the roller, which in turn counteracts the bending moment by which the roller is bent due to rolling force.
- Axially displaceable intermediate rollers with non-cylindrical outer contour are used in the solution according to DE 30 00 187 A1 and DE 22 06 912 A1.
- the principle used is based on the introduction of transverse and bending forces and thus bending moments in the corresponding rolls.
- the effect is usually not sufficient to compensate for the different deflection states of a rolling mill due to different Walzgutfesttechniken and widths. Therefore, additionally different crowned ground rolls are used or roll shifting systems are provided.
- These axial displacement systems operate either on the principle of internal load transfer or the variable equivalent crowning of two rolls (so-called Continuous Variable Crown - CVC system).
- the use of different spherical rollers is cumbersome. Displacement systems are also expensive and lead in particular in the case of load transfer to unwanted pivoting movements of the framework.
- the present invention has the object, a rolling stand of the type mentioned in such a way that it is possible in a simpler and less expensive manner and with as few elements as possible to initiate a bending moment counteracting the bending moment in the roll. It should be possible to dispense with elaborate mechanisms, while still ensuring that bending of the roller, which stem from the rolling forces, can be compensated as well as possible.
- each chock is connected to a bending lever and the adjusting element is arranged so that its contact force is introduced at a remote from the center plane of the chock in the bending lever and on this on the chock.
- the positioning element acts on a cross-member, which is connected via two joints, each with a bending lever.
- two adjusting elements are provided, which are arranged mirrored to a center plane of the roller. These can be connected via two joints, each with a bending lever. The two joints can be connected to each other via a crossbar.
- the at least one adjusting element is preferably a hydraulic piston-cylinder system.
- the one or more Anstellelemente can be supported on a stationary crosshead of the rolling stand.
- a structurally advantageous solution provides that the roller, together with the mounting pieces and bending levers, is arranged displaceably in the direction perpendicular to the conveying direction of the rolling stock in the roll stand between two side cheeks of the roll stand.
- the bending levers can surround the chocks laterally and form a sliding surface to the side cheeks.
- bending levers and the chocks means may be provided which are suitable for introducing a torque from the bending lever in the chock.
- this is a tongue-and-groove connection extending in the direction of the axis of rotation of the roller.
- the rolls mentioned here may be work rolls in duo-stands or back-up rolls.
- the proposed solution thus provides that the rolling force induced deflections of the set of rolls and the associated imperfections of the roll gap geometry are largely avoided by the rolling force itself bending moments on the rollers (in particular on the support rollers and the work rolls) are constructed, the bending effect of the rolling force-induced deflection of the rolls is opposite.
- the present invention is based on a scaffolding principle which prevents the unwanted rolling force-induced roller deformations predominantly and almost independently of rolling force and thus has the potential to manage with a minimum of active flatness adjustment systems. Nevertheless, the proposal according to the invention can also be combined with all known control systems.
- FIG. 1 shows schematically a work roll together with its two chocks and a bending bridge, wherein the roll is employed by a setting element, viewed in the conveying direction of the rolling stock,
- FIG. 2 an alternative to FIG. 1 embodiment of the device with two Anstellelementen
- FIG. 3 shows the device according to FIG. 1 seen from the direction A according to FIG. 1, FIG.
- FIG. 4 shows a mechanical replacement model for the device according to FIG. 1 with indication of the forces and geometry variables
- Fig. 5 shows the course of a ratio y / yunkomgiert over a ratio x / L for different values S / L.
- a rolling mill is shown in sections, which has a work roll 1 with a rotation axis a, which is mounted in two chocks 2 and 3 in a known manner.
- the work roll rolls a rolling stock, not shown, that is rolled in the conveying direction F (perpendicular to the drawing plane).
- the work roll 1 is pressed by means of a hydraulic adjusting element 4 against the rolling stock.
- the deflection of the roller 1 due to the contact with the rolling stock is superimposed on a counter-bending moment, which is generated by two bending levers 5 and 6.
- the two bending levers 5, 6 are rotatably connected to the built-in pieces 2, 3. They are in the middle region of the device at two joints G by means of two joints 8 and 9 with a traverse 7 tied, on which the adjusting element 4 acts.
- the adjusting element 4 is supported on a crosshead 10 of the roll stand.
- the roll length is indicated by L B and is smaller than the distance L of the center planes ME of the two chocks 2, 3. Also indicated is the distance / two rolling bearings, which are arranged in the chock 2, 3 and store the roll neck.
- the arrangement is symmetrical overall, ie mirror-image to a center plane M w of the roller. 1
- FIG. 2 differs from that according to FIG. 1 only in that here two setting elements 4 are used.
- the comments on Fig. 1 apply here otherwise.
- FIG. 3 shows in the view A according to FIG. 1 how the roller 1 together with chocks 2, 3 and bending levers 5, 6 is displaceably arranged in the vertical direction in the rolling stand.
- the roll stand on two side cheeks 11 and 12, the respective sliding surfaces 13 and 14 have, so that the bending lever 5, 6 can slide vertically up and down.
- a scaffold loaded by a rolling force distribution would be set up in the same manner - centrically and in the same width - as the rolling stock acting on the work roll.
- a rotating roller can not be hired in the middle by one or more standing adjusting cylinders - the location of the introduction of rolling force can only be the chock with the roller bearing.
- the aim of the present solution is to use the basic principle of ideal rolling force application, namely along the roll mantle.
- the loaded in the same way as employed roller experiences no bending moment - both locally and as a whole.
- the roll axis remains straight.
- the fact that the rolling force can be initiated only on the chocks and not along the roll shell, means that a compensating bending-back torque can not be initiated locally, but also only on the chock in the roll.
- the Anstellzylinderkraftkraft is not centrally applied to the chocks or roller bearings, but at a suitable distance. The resulting moment must be initiated by a sufficiently stable mechanism in the chock.
- Fig. 1 shows such an arrangement with a central adjusting cylinder.
- the contact force can also be applied by a plurality of cylinders, as shown in Fig. 2 with two Anstellzylindern. It is essential that a suitably dimensioned distance of the load application point to the chock is present and the connection of the bending lever with the chock can transmit a moment.
- the combination of chock and bending lever must be designed so that the chock can not be wedged in the stator window and can not be moved in the sequence for employment. Furthermore, the changeability of the support roller must be ensured.
- the movability of the roll can be achieved, for example, by the fact that the cheeks of the bending lever comprise the outer sides of the piece of construction and the movement takes place between the cheeks and the roll stand, as can be seen in FIG.
- the chock is designed so that the compensating bending moment is introduced by a superimposed on the other forces pair of forces on the chock, the lines of action of the force pair should correspond approximately to the positions of the radial roller bearings to largely avoid torque loads on the bearings.
- the adjusting cylinder bears on the one hand on the force-transmitting bridge, consisting of the two bending levers (including traverse), on the other hand, it relies on the crosshead of the rolling mill.
- the same principle can also be applied to the non-actively employed and generally lower set of rolls, whereby the setting cycle Linder can be replaced by a Passlinienangnagna or simply by a fixed pressure piece.
- the pivoting of the framework takes place, at least in the case of a central adjusting cylinder, preferably by the appropriately equipped balancing cylinder. Due to the lower hysteresis of these small cylinders, this also requires more precise pivoting.
- the Zylinderanstellkraft F A acts centrally on the traverse 7 of the bending bridge, which comprises the two bending levers 5 and 6 in addition to the traverse 7, wherein the connection between the bending levers 5, 6 and the traverse 7 via joints 8 and 9 takes place.
- the roller 1 is simplified as a round bar with over the length of constant cross-section shown and centrally loaded with a single force F w from the rolling process.
- the system does not experience any asymmetries in this simplified representation and is weight-free, so that the balancing forces FBI and F B2 compensating the weight of the roller and its attachments are equal to zero.
- the bending levers 5, 6 and the roll chocks 2, 3 are combined to form a body - ultimately, a division into two components is optionally only a lighter structural design.
- the connection of roll chock / bending bridge takes place in this replacement system by simple fixed bearing whose distance in the chock / is.
- the chock centers (center planes ME) have the bearing center distance L, the distance of the joints 8, 9 from the respective chock centers is S.
- the restoring compensation moment M « is determined to be
- E is the modulus of elasticity of the roll material
- I is the area moment of inertia.
- This function is shown as a function of the distance parameter S in FIG. 5.
- S / L 0.5 means that the bending lever is the maximum length, d. H. has half the bearing center distance and thus the rebound moment is greatest.
- FIG. 5 shows, for this simplified example, that a substantial compensation is to be expected for bending lever lengths of about 30% of the bearing center distance L.
- L bearing center distance
- the system according to the invention is preferably also used in combination with the previously known systems for roll gap influencing.
- variable lever lengths S that is, locations of the hinge points G
- active control can be used for active control.
- the invention enables a simple scaffolding design, with the property that the roll force induced deformations of the set of rolls are compensated automatically, without external intervention and properly dimensioned.
- the same would be achieved with conventional design only with significantly thicker back-up rolls or a complex, active flatness correction system.
- the roll would have to be more than 70% thicker in order to have a similar behavior to the mechanism according to the invention. This would have an enormous enlargement of the framework with corresponding additional costs.
