Definitions

  • the invention relates to a roll stand with two work rolls mounted in chocks in the roll stand and supporting the work rolls. the upper and lower back-up rolls also mounted in the roll stand. and, if necessary, intermediate rolls provided between the work and backup rolls. wherein the work rolls are arranged in a vertical plane extending parallel to the roll axes and are adjustably supported therein, and one of the roll pairs is provided with a roll bending device for bending the rolls of this roll pair in a plane parallel to the rolling direction.
  • a generic roll stand is known for example from DE 33 31 339 C1.
  • This known rolling mill proposes. to provide the intermediate rolls of a roll stand with work rolls, support rolls and intermediate rolls arranged between work rolls and support rolls with a roll bending device with which the intermediate rolls can be bent in planes parallel to the rolling direction.
  • This Rolling mill should be mastered a problem of rolling mill technology, which consists in the production of a flat or tension-free strip. Since rolls generally bend over the length of the bale under the rolling load, even if large support rolls are used, a thickness error occurs regularly across the width of the material to be processed, which leads to different strip elongations across the width of the rolling stock. This means waviness of the strip, which can only be prevented incompletely by crowning the work rolls, because the deflection of the rolls depends on the rolling force and also changes with their change and changes in the strip width.
  • the generic roll stand is designed so that the intermediate rolls are provided with a roll bending device.
  • the constructive design of such roll bending devices leads to difficulties, especially since the space requirement of such bending devices severely impairs the accessibility of the rolling mill and the arrangement of such bending devices, for example on the work rolls, is not readily possible, which is why known rolling mills of this type usually the work rolls are designed as drag rolls.
  • the present invention lies The object of the invention in such a way that the other parts of the rolling mill, in particular the drive configuration and the devices for changing the rolls, are not affected by the devices for bending the rolls.
  • each chock of the work rolls is pivotally mounted about a central vertical axis in the stand window of the roll stand and each work roll is bendable about the pivot axes of its two chocks in the horizontal plane parallel to the rolling direction.
  • the invention therefore proposes to rotate the chocks in a horizontal plane, so that the necessary bending devices become very simple. This is particularly the case if, according to a further feature of the invention, it is provided that the chocks of the work rolls are provided on both sides with the bearing shells facing the stator, which correspond to correspondingly designed guide strips in the stator window, the common radii centers of the guide strips and bearing shells of each chock the vertical axis about which the chock is pivotable.
  • the chocks of the work rolls are provided with extensions protruding from the stator window, on which bending cylinders act which are supported on the roll stand on both sides of the chocks.
  • the proposals of the invention can very easily and easily introduce a horizontal bending moment via the roller bearings into the work rolls without the need for complex bending devices. For example, hinder the installation and removal of the work rolls.
  • extension-side bending cylinders are positively connected to the extensions of the chocks with the interposition of the roller lock.
  • the present invention allows the work rolls to be driven in a particularly advantageous manner, the drive of the work rolls not being affected by the actual bending device due to the constructive work roll bending device.
  • the work rolls are bendable in opposite directions. This measure allows a particularly favorable vertical Achieve bending shape so that even with very thick back-up rolls the work rolls can have a favorable influence on the flatness and the profile of the rolling stock.
  • the only drawing figure shows a roughly simplified representation of a horizontal section through the rolling stand of the invention at the level of the rolling stock plane.
  • the rolling mill shown is configured for flat products and in the example has four rolls, namely two work rolls, which are designated by 2, and two backup rolls (not shown).
  • the cut runs through the four stand posts labeled 1, in which the one visible work roll 2 is mounted with its chocks 3.1, 3.2.
  • the chocks at 3.1 and 3.2 are provided on both sides in the direction of the stand 1 with bearing shells 4, which correspond to guide strips 5.1 and 5.2, which are arranged in the stand window on the stands 1.
  • the chocks 3.1, 3.2 with their bearing shells 4 are in a manner not shown in the guide rails 5.1, 5.2 vertically, ie perpendicular to the plane of the drawing.
  • the bearing shells 4 and the guide strips 5.1, 5.2 have such curved bearing surfaces that their common center of radius lies on the vertical axis X, about which the chocks 3.1, 3.2 can be pivoted.
  • the chocks 3.1 3.2 In order to pivot the chocks 3.1 3.2, they are provided with extensions 6 protruding from the upright windows, on which bending cylinders 8.1, 8.2 act, which in turn are fixed at 9 on uprights 1 of the roll stand.
  • the bending cylinders 8.2 On the drive side where the Drive spindle can be seen at 10, the bending cylinders 8.2 are connected directly to the extensions 6 of the chock 3.2 and connected to the stand 1.
  • the bending cylinders 8.1 actuate simultaneously displaceable plates 7, with which the chock 3.1 on the expansion side can be locked with the stand 1.
  • the plates engage in recesses 11 on the extensions 6 of the chock 3.1, the plates 7 being able to be pivoted, for example, about pivot axes 12 into a locking position and into an unlocking position.
  • the bending cylinders 8.1 not only take on the function as bending cylinders for the work rolls 2 about the axes 6, but also have the function of the locking cylinders which are
  • the rollers 2 are held by the support rollers (not shown), so that when bent in the dashed form, a vertical displacement component also results, with which the flatness and profile of the strip can be influenced.
  • the roll gap as in known methods, can be adjusted in its vertical extent across the width.
  • the invention represents a particularly structurally simple solution which allows the roll change of the work rolls to be carried out without problems and does not hinder the drive of the work rolls, if desired.
