Definitions

  • the invention relates to a method for operating a rolling mill, in particular a strip rolling mill, with, for example, a plurality of duo or quarto roll stands connected in series.
  • the support and work rolls In order to counteract the entanglement of the rolls and the tensions caused thereby in the strip, the support and work rolls have been installed in the roll stand offset according to the expected entanglement in the running direction of the rolling stock, but without an exact position of the roll axes relative to one another during the subsequent rolling process . Even when using additional roll bending devices, the desired results cannot be achieved.
  • the object of the invention is to insert the rolling mill rolls with their chocks into a rolling stand such that the rolling mill rolls are always aligned with their axes in the vertical plane during the rolling process.
  • a method is provided according to the invention in which, before the occurrence of rolling force, the chocks of the duo rollers or, in the case of the four-high rolling mill, the chocks of the support rollers are brought into contact with the stator side lying in the direction of the transverse component from the rolling force and are held in this defined position during the rolling process solely by the force obtained from the rolling process.
  • a device for performing the method is designed so that each chock is assigned at least one actuating cylinder provided on one side in the roller stand.
  • actuating cylinders are used which, when loaded with their pistons, protrude into the stator window from one side and bring the chocks into the stator window against the opposite stator side. The pistons are then withdrawn so that no additional force acts against the chocks from the cylinders during rolling, which could adversely affect any thickness control that may be present.
  • Cylinders whose pistons extend into the stator window are known per se (FR-PS 1 503 319).
  • the known cylinders are in no way used to bring an installation piece against a stator side in a defined manner.
  • cylinders are provided which are assigned exclusively to the upper support roller chock, in such a way that they are flush with one another, so that when the cylinders are acted upon, the pistons extend from each stator side into the stator window and clamp the chock in the stator window between them .
  • the hydraulic locking of the upper support roller chock should make it easier to change the work roll.
  • each of the chocks 3 are assigned to the support rollers 2 and, when loaded with their pistons 8, which then protrude into the stator window 6, press against the chocks until they fit perfectly against the surfaces 6a of the roller stand 1 or the stator window 6 opposite the actuating cylinders 7.
