Definitions

  • the invention relates to a method for rolling strips axially movable rollers.
  • roll wear Another influencing variable St is roll wear, which is primarily occurs where the rolled strip comes into contact with the rolls, and which reduces the diameter of the rollers.
  • JP 61-52915 discloses a method for influencing the roll gap profile, both thermal and wear-related Changes in crowning are determined and by shifting the work rolls be adjusted in such a way that as flat a strip as possible is rolled can be.
  • GB 2 198 981 A discloses differently designed rolls, by means of of which the thickness of the rolled strip can be influenced accordingly.
  • the rollers have a cut similar to the well-known CVC cut and, like the CVC rollers, serve the thickness of the strip influence in the border area, in the quarter area or in the middle area to be able to.
  • Roll materials are used whose wear is negligible is small, then at least one is disrupting the rolling programs Minimized influencing variable over the width of the rollers been. Because the roller wear is basically contrary to the increasing thermal crowning works, it takes part in the rolling process low-wear rollers even more noticeable.
  • the invention is therefore based on the object of an actuator to demonstrate the annoying thermal crowning effect counteract simple and inexpensive to free rolling plans to be able to design.
  • wear-resistant rollers with at least executed in one of their end regions with enlarged radii Rolls are shifted against each other in such a way that the rolled strip in its width with areas of smaller radius in Stand in contact and that with increasing warming and thus thermal Bombing by shifting the roller areas in opposite directions their larger radius' pushed over edge areas of the rolled strip become. This ensures that the edge region elevations of the Band that occur due to the increasing thermal crowning would be eliminated.
  • the amount of displacement can e.g. determined in a calculator be the thermal crowning based on a calculation model determined online, taking values about the contour of the roller, its elastic deformation, etc. can be used to achieve an optimal Move position and thus set a desired belt contour.
  • rollers of a pair of rollers are each in the end areas of their bales with opposite their middle area increased diameter are executed.
  • Figure 1 is an upper work roll 1 and a lower work roll 2 can be seen. Between the work rolls 1, 2 that is too rolling band 3 arranged.
  • the upper work roll 1 has a diameter on its right side on that with the diameter of the left side of the bottom Work roll 2 matches. They are shown very exaggerated two work rolls 1, 2 at their other two ends 4, 5 slightly larger diameter. In the contact area of band 3 with the work rolls 1, 2 is also shown greatly exaggerated Thermal crowning 6, 7 of the rollers 1, 2 can be seen.
  • the work rolls 1, 2 are opposite in the direction of arrows 8, 9 shifted against each other that their edge areas 4, 5 larger Diameter are shifted over the edge areas of the rolled strip.
  • Figure 2 shows an upper work roll 1 'and a lower work roll 2 ', the bale ends 4, 4' and 5, 5 'different Have diameter.
  • the slopes 10, 10 ', 11, 11' are also different so that different thermal crowning are compensable.
