Abstract
Description
- 1. Field of the Invention
- The invention relates to a multi-high roll stand with a plurality of driven support rolls and with a number of working rolls frictionally driven by the support rolls, wherein the working rolls form a rolling gap which defines the thickness of rolling stock guided between the working rolls in a rolling direction.
- 2. Description of the Related Art
- For rolling a rolling stock, for example, in a rolling mill, a roll stand can be used. The roll stand is often a so-called multi-high roll stand and comprises a plurality of working rolls and a number of support rolls. The support rolls are conventionally driven by a correlated drive wherein each support roll is in frictional contact with a correlated working roll. By means of the thus provided frictional drive action, each working roll is then driven by the correlated support roll. The working rolls act together onto opposed sides of the rolling stock wherein the thickness of the rolling stock, guided between the working rolls through the multi-high roll stand, is determined by the roll gap formed between the working rolls. The thickness of the rolling stock guided through the multi-high roll stand can be adjusted by means of a corresponding variation of the pressing force, which is also referred to as rolling force, of each working roll.
- When processing comparatively high-quality rolling stock such as, for example, steel or stainless steel, it may be important, in particular, for the so-called skin pass rolling step of such a rolling stock, that the respective multi-high roll stand is configured for covering a comparatively wide rolling force range. A control provided for this purpose, by which, inter alia, the thickness of the rolling stock is adjusted, thus covers with its value range also a comparatively large rolling force range. However, for such a system the essential components are conventionally configured such that measuring errors, such as, for example, errors in the rolling force measurement, depend on the maximum value of the respective measured value. In particular in the case of a rolling force measurement, whose value range covers a comparatively wide rolling force range, the absolute measuring error is thus comparatively large.
- On the other hand, in the so-called skin pass rolling of IF (interstitial free) steel, it is necessary to adjust, even for such multi-high roll stands, comparatively small rolling forces. Accordingly, for a multi-high roll stand, which is to be used, on the one hand, for skin pass rolling of IF steel and, on the other hand, for covering a generally comparatively large rolling force range, the measuring error for determining the rolling force can be greater than the actual rolling force required for skin pass rolling of IF steel. The thickness and/or skin pass rolling control for such a multi-high roll stand is thus comparatively imprecise.
- It is an object of the present invention to provide a multi-high roll stand of the aforementioned kind which, on the one hand, can be used for a comparatively high rolling force range and, on the other hand, can be adjusted especially precisely, even for comparatively small rolling forces, with respect to its roll gap and thus with respect to the thickness of the rolling stock. Moreover, a method for operating such a multi-high roll stand is to be provided which makes possible, even for comparatively small rolling forces, a particularly precise thickness control of the rolling stock.
- In accordance with the present invention, this is achieved in regard to the multi-high roll stand in that the working rolls are movable in a direction substantially parallel to the rolling direction for adjusting the gap width of the roll gap.
- The invention in this connection is based on the consideration that the thickness adjustment of the rolling stock can be realized with an especially high precision in that it is carried out via an adjusting parameter having a comparatively large adjusting stroke. The actual adjusting parameter for the thickness adjustment, i.e., the position of the respective working roll perpendicularly to the rolling direction for forming the roll gap, however, has a comparatively minimal stroke adjustment. It is therefore transformed into a parameter with comparatively large adjusting stroke, i.e., the position of the working roll in a direction parallel to the rolling direction. When adjustments are carried out, the working roll rolls on the surface of the spatially stationary support roll so that a defined relation between the position of the working roll perpendicularly to the rolling direction and its position in the rolling direction results. In particular in this area directly below the support roll the geometric conditions are such that a comparatively generous spatial movement of the working roll in the rolling direction results in only a minimal change of its position in the direction perpendicularly to the rolling direction.
- Conventionally, a rolling mill is configured for passing the rolling stock therethrough substantially in a horizontal rolling direction. Advantageously, in an adaptation to this configuration, the working rolls are accordingly movable substantially horizontally for adjusting the gap width of the roll gap.
- For a particularly reliable automated thickness adjustment of the rolling stock, a control device is correlated advantageously with the multi-high roll stand. It is expediently connected at the output side with a number of adjusting devices, each one being correlated with a working roll, respectively, for adjusting the position of the working roll in the rolling direction. The control device presets in this connection a nominal or preset adjusting value for each adjusting device, respectively, for positioning the respective working roll in the rolling direction wherein the respective adjusting value is selected as a function of a measured actual value of the thickness of the rolling stock.
- For the adjusting devices acting on the working rolls different configurations can be provided, for example, in the form of rotary spindles. Advantageously, the adjusting devices are, however, hydraulic adjusting devices with which an specially high adjusting precision can be obtained.
- For a timely and particularly reactive control, a direct loading of the control device with a measured value characteristic of the thickness of the rolling stock is advantageously provided. For this purpose, the inlet side of the common control device is advantageously connected with a measured value (measurement) transponder for determining the thickness of the rolling stock.
- In order to be able to have available in the way of a selectable rolling program a suitable pre-defined operating parameter for a plurality of different purposes, according to a further expedient embodiment a memory component is correlated with the common control device in which a number of nominal values for the thickness of the rolling stock can be stored. As a function of the actual use of the roll stand, it is possible in a very simple way to switch between different rolling programs in that a new currently desired valid nominal value for the thickness of the rolling stock is selected, respectively, from the nominal values stored in the memory component.
- With respect to the method for operating a multi-high roll stand, the object is solved in that the thickness of the rolling stock is adjusted by a movement of the working rolls in a direction which is substantially parallel to the rolling direction.
- The adjustment of the position of the working rolls in the rolling direction is advantageously performed by means of a comparison of a currently determined value of the thickness of the rolling stock with the nominal value for the thickness of the rolling stock.
- The advantages obtained with the invention reside in particular in that by the movement of the working rolls in the rolling direction for the purpose of adjusting the gap width of the roll gap the thickness of the rolling stock is affected indirectly and by means of a control parameter with a comparatively large adjusting stroke. In particular as a result of the geometric conditions between the support rolls and the working rolls, the displacement strokes of the working rolls, i.e., the positional changes required for obtaining a predetermined change in the gap width of the roll gap, are especially large so that the sensitivity and precision for adjusting the gap width of the roll gap are particularly high. Moreover, the position adjustment of the working rolls in a direction substantially perpendicular to the rolling force is such that a coupling to the rolling force is realized only by the deflection within the working roll itself. Moreover, for such an adjustment of the gap width of the roll gap the stand friction is especially minimal.
- One embodiment of the invention will be explained in the following with the aid of the only drawing FIGURE showing a multi-high roll stand.
- The FIGURE shows a multi-high roll stand1 as a four-high stand and comprises an upper working roll and a
lower working roll support roll 6, 8, respectively. Theworking rolls working rolls - The
support rolls 6, 8 are driven by a drive, not illustrated in detail, receptively, and are rotated about their central axis. Eachworking roll support roll 6, 8 so that it is entrained by the respective correlated drivensupport roll 6, 8 by friction. -
Rolling stock 10 is guided between theworking rolls working rolls roll gap 12 in a direction substantially perpendicular to the rolling direction x which roll gap determines the thickness of therolling stock 10 leaving the multi-high roll stand 1. - The multi-high roll stand1, on the one hand, is configured for loading the
rolling stock 10 by means of a rolling force, that is substantially oriented perpendicularly to the rolling direction x, across a comparatively large rolling force area. In this connection, by means of an adjusting device, not illustrated in detail, the rolling force is adjustable at thesupport rolls 6, 8 and is transmitted by means of theworking rolls rolling stock 10. The multi-high roll stand 1 is configured for comparatively minimal rolling forces, as they are required, for example, for skin pass rolling of IF steels, as well as for comparatively high rolling forces and is thus particularly flexible with regard to its use. - On the other hand, the multi-high roll stands1—particularly for comparatively small rolling forces—is configured for an especially precise adjustment of the thickness of the rolling
stock 10. For this purpose, acontrol device 20 is correlated with the multi-high roll stand 1 via which theworking rolls roll gap 12, are movable in a direction substantially parallel to the rolling direction. For this purpose, each workingroll roll adjusting system adjusting system 22 correlated with the workingroll 2 comprises in this connection a hydraulically actuated adjustingpiston 26 which is loadable by means of an adjustingdevice 28 configured as a pressure transponder with an adjusting pressure. In analogy, theadjusting system 24 correlated with thesecond working roll 4 comprises an adjustingpiston 30 which is loadable by means of an adjustingdevice 32 in the form of a pressure transponder with adjusting pressure. - For adjusting the position of each
working roll data lines device data lines devices respective adjusting device working roll - The
common control device 20 is configured for readjusting the position adjustment of the working rolls 2, 4 in the rolling direction x as a function of the thickness of the rollingstock 10. For this purpose, the input side of thecommon control device 20 is connected by means of thedata line 40 with a measured value (measurement)transponder 42, configured to determine the thickness of the rollingstock 10. The common control device readjusts by means of the adjusting values S the positions of the working rolls 2, 4 in the rolling direction X until the thickness of the rollingstock 10 measured by the measuredvalue transponder 42 corresponds to a nominal (preset) value Sw. The nominal value Sw, as a function of a predetermined use, can be selected from a plurality of nominal values Sw provided in adata memory system 44 connected to thecommon control device 20. - As a result of the continuously maintained contact provided by the rolling force between each working
roll support roll 6, 8, the respective workingroll support roll 6, 8 correlated therewith. As a result of these boundary conditions, the movement of the respective workingroll roll roll gap 12. As a result of the geometric conditions with regard to the arrangement of the working rolls 2, 4 substantially centrally between the support rolls 6, 8, a comparatively generous spatial movement of the working rolls 2, 4 in a direction parallel to the rolling direction x causes only a minimal change of their position in a direction perpendicular to the rolling direction x. Accordingly, across a comparatively large adjusting stroke in the direction parallel to the rolling direction x, a comparatively minimal and thus high-resolution change of the gap width of theroll gap 12 can be obtained. Accordingly, the control of the adjustment of theroll gap 12 is of relatively high precision even for comparatively minimal rolling forces. - While specific embodiments of the invention have been shown and described in detail to illustrate the inventive principles, it will be understood that the invention may be embodied otherwise without departing from such principles.
