Definitions

  • the invention relates to a method for lubricating rolls, in particular of work rolls of a roll stand and rolled rolled and conveyed between these rolled strip, wherein a lubricant-gas mixture, a lubricant-water-gas mixture, a lubricant-water mixture and / or a grease-medium mixture is applied to the rollers or the rolled strip on the upstream side.
  • the rolling stand comprises a plurality of mutually supporting rollers, such as a work roll, which comes directly into contact with the rolling stock and in turn rolls on a usually larger support roll or an intermediate roll.
  • Roll-gap lubrication systems are integrated in many hot rolling mills for rolling a metal strip. These are used to improve the surface quality of the work roll and the strip and now belong to the usual equipment of a rolling mill on which high-quality tapes are to be produced.
  • the system in which water as a carrier medium is mixed together with oil and applied to the rolled strip or the working or backup roll is widely used.
  • lubrication is common.
  • lubricant is applied to the rolled strip and / or the work roll and / or injected into the roll gap.
  • the mixture of oil and water takes place far away from the mill stand.
  • an emulsion is used, which is prepared in a complex process in a circulation system, cleaned and fed back to the lubrication system.
  • WO 03 002277 A1 From the WO 03 002277 A1 are a method and apparatus for cooling and / or lubricating rollers, in particular of the work rolls, a rolling stand known in which water in the form of sprays as a cooling medium and oil, an oil-air mixture, an oil-water mixture, a Oil-water-air mixture or fat mixtures can be used as a lubricant.
  • a combined use of supercooling of the belt and roll surface and the roller lubrication on the scaffold inlet side is proposed, in which the two media - water and lubricant - the rolls or the strip fed separately and to different application sites of the roll surface be applied. Separate feeds to the spray bars are provided for water and the lubricant respectively.
  • this object is achieved by a method having the features of claim 1.
  • the aim of the new lubrication method is to produce the lubricant shortly before use or application, similar to hot rolling, and thus to avoid expensive preparation in a closed circuit.

  • the advantage of the new lubrication process in the cold rolling process is that the oil concentration in the lubricant can be changed very quickly and flexibly. This allows the lubricant to be optimally adjusted to different materials to be rolled, to different belt speeds, to changing approvals and to the respective rolling stand. Furthermore, different oils and lubricating media for different applications can be provided.
