Definitions

  • reaction forces are applied to the necks of the backing rolls to withstand and counter the pressure which the strip of sheet metal exerts on the rolls during rolling.
  • the backing rolls are thus forced to bend, their fibres being compressed by the strip, with resulting curving.
  • the working rolls follow the deformation of the backing rolls and, as a result, the rolled strip has a transverse section which, instead of being rectangular, tends to take on a form substantially like a biconvex lens, that is, with a greater thickness in the middle.
  • a roll comprising a cylindrical core and characterised in that it includes:
  • the support ring 14 has an axial length less than the axial length of the corresponding expansion ring 12 and hence of the chamber 13 in which it is axially movable.
  • backing roll may be used either in an existing four-high stand, or in a conventional six-high stand as an intermediate roll.
  • a backing roll according to the invention may be used together with conventional corrective loads further increasing the working precision. It will thus be clear that a backing roll according to the invention solves the technical problem previously explained, ensuring rolling results which are technically consistent, with reasonable production, installation and operating costs.
