Definitions

  • the invention relates to a roller stand in a closed frame construction, especially for heavy roll stands for the rolling of sheets and strips, consisting of two the stand window for receiving and guiding the Stand spars delimiting roll chocks with mutually parallel Inner surfaces and the upper and lower crossheads connecting the uprights.
  • Rolling mills of conventional design basically consist of two stands, in which the rollers, which run in bearings supported by chocks, arranged are.
  • the stands are connected to each other at the top and bottom by cross-connecting parts connected; Cross-connection parts and stands form the rolling stand.
  • the stands take as load-bearing structural parts of the rolling stand all in the rolling process occurring forces. Therefore, the stand must have high strength with low Have shape change and at the same time the favorable arrangement of all elements of the Enable scaffolding.
  • one-piece versions of the Stand in closed frame construction preferred;
  • the rolling Resulting of the rolling force is directed approximately perpendicularly, so that on the Overall system two equally large opposing forces act which the Try to push the crossheads apart.
  • the crossheads, which are fixed to the uprights are only subjected to bending.
  • the largest Tension in the stand can be assumed on the stand bars in the window areas, because the stand bars - in addition to the tensile stresses - due to the acting bending moment be bent towards the window.
  • the stand window is constricted, i.e. the clear distance between the inside of the uprights is reduced by the Rolling load.
  • the object of the present invention is based on those described Problems, a roller stand in a closed frame construction like this to design that - while avoiding stress concentrations in the stand - the constriction of the stand window resulting from the rolling forces between the uprights is minimized to an acceptable level.
  • the invention proposes that the Column window facing away from the outside of each column, from the Crossheads starting to reduce the cross-sectional areas of the uprights back up towards the stand window, the smallest Column cross section in the middle area between the upper and lower Crosshead lies.
  • each uprights are concave in the longitudinal direction running contours, so that the cross-sectional areas of the uprights, from starting from the crossheads, continuously up to the middle area of the Reduce the uprights.
  • the reduction by an in Longitudinal circular arc shape of the outside of each Stand spar is writable.
  • the center of the radius of the contour descriptive circular arc lies in the middle area outside of the uprights.
  • each uprights in the longitudinal direction have parabolic contours, or for example the bending line correspond to a beam on two supports.
  • each upright prefferably forms in the longitudinal direction as contours that can be described by polygons, in In extreme cases, the polygon could be formed from three points.
  • FIG. 1 is a three-dimensional, highly simplified representation Roller stand shown in a closed frame design, which in the Introduction to the description is described as the prior art.
  • the roll stand is overall designated 1. It consists of the two uprights 2 and 3, the are connected to each other via the upper 4 and lower crosshead 5. Inside the through the formation of this stand, the closed frame remains stand window numbered 6, the one formed on the stand spars 2 and 3 Inner surfaces 7 flat and with respect to the respective opposite upright 2 and 3 are formed in parallel planes.
  • the upper crosshead 4 of the Roller stand 1 has a hole for the pressure nut, which is related is irrelevant with the present invention.
  • the uprights 2 can be seen and 3 cross sections on that between the upper crosshead and lower crosshead have the same dimensions.
  • FIG. 2 schematically shows the deformation of the stand which occurs when the rolling forces Y and Y 'bend apart the upper and lower crossheads 4, 5 of the roll stand 1 in the vertical direction.
  • the uprights 2 and 3 as shown by the broken line 8 shows, bend inwards and reduce the clear width of the upright window.
  • the extent of this structural retraction of the stator window 6 depends on the size of the effective forces Y and Y ', the dimensions L1 and L2 of the stator crossheads 4 and 5 and stator bars 2 and 3 and their resistance moments J 1 .
  • the uprights 2 and 3 are tapered in the direction of the stand window 6.
  • the Provide outer sides 10 of the uprights with a contour that by a Circular arc with the radius R is writable, the center of the circle with the radius R on an imaginary, through the center 11 of the roll stand 1 horizontal is outside the stand.
  • the radius R is in Embodiment chosen so that the degree of retreat of the two Upright stiles 2 and 3 approx. 30% of the unstrangled stile according to FIG. 1 is.
  • a roll stand is used for calculation purposes a total height of 14,900 mm and a stator beam thickness of 960 mm went out.
  • the height of the lower and upper crosshead was 2300 mm accepted.
  • the degree of constructive retreat of the outside of each Stand spar was made with 250 mm for variant 1 and 295 mm for variant 2 assumed, both based on the uprights of a generic Roll stand according to Figure 1 with an assumed spar thickness of 960 mm.
  • FIG a roll stand according to the invention in a three-dimensional diagram and in Dependence on the percentage rolling force shown. It can also be seen here that - even with 100% rolling force - a clear one in the center area of the stand decreasing, towards zero reduction in constriction takes place, so that a roller stand designed according to the invention in a simple manner Solves task.
