Definitions

  • the invention is based on a roll stand for rolling strips straightened, with work rolls that rest on backup rolls Support intermediate rolls, the work rolls and / or the Back-up rolls and / or the intermediate rolls against each other axially are arranged displaceably and wherein at least the Work rolls and / or the intermediate rolls one over the Entire roll length extending curved or have a cylindrical contour.
  • annular recesses according to the invention can be in their shape and size arbitrarily chosen and thus the to rolling strips can be optimally adjusted. It is after an advantageous embodiment of the invention possible, annular recesses for the intermediate rolls choose which in shape and size from the Cut-outs in the work rolls differ.
  • the work rolls (13a, 13b) and the intermediate rolls (12a, 12b) are each one-sided at one of their roller ends provided annular recess (15a, 15b, 16a, 16b) and so arranged that these recesses (15a, 15b, 16a, 16b) above and below the rolling stock (14) with respect to Work rolls (13a, 13b) and the intermediate rolls (12a, 12b) opposite each other in the area of the band edges.
  • FIG. 3 shows the same strip widths and the same rolling load 1 with a roller arrangement according to the invention resulting symmetrical roll gap profiles applied.
  • the limited to the band edge area allows Freedom of positioning an individual influence on the Band edge in terms of flatness and profile (edge drop). It is thus possible with the roller arrangement according to the invention, Profile and flatness independent of belt edge and belt center from each other by appropriate shift of work or the intermediate rollers.
