Definitions

  • the invention relates to a lubricating device for applying a lubricant during rolling, in particular cold rolling, a rolling stock.
  • the rolling stock is a metallic rolled strip, which is guided through a nip between two rotating work rolls of a roll stand in order to reduce the thickness of the rolled strip.
  • the lubricant With the lubricant, the friction between the rolled strip and the work rolls in the nip is reduced.
  • the lubricant is applied with the lubricating device, for example on a work roll or on a support roller or before the nip on the rolling stock.
  • Such lubricating devices usually have nozzles for spraying the lubricant.
  • the arrangement of the nozzles depends on several parameters. In particular, it depends on the distance between the nozzles and the surface on which lubricant is to be applied. This distance results in turn from technological requirements of lubricating profile production as well as from space requirements on existing rolling stands. Further, the nozzle arrangement depends on the spray angle of the nozzles to be used, which affects the distance of the nozzles from each other. The complex dependence of the nozzle arrangement on such parameters makes it difficult to design a lubricating device that can be used for various rolling stands and rolling processes or that can be flexibly adapted to different rolling stands and rolling processes.
