Definitions

  • the present invention relates to a method and an apparatus for rolling rolling.
  • the method and the device are preferably used in cold rolling.
  • cooling lubricants In cold and hot rolling of metallic strips, fluids are usually applied to the rolls and / or to the rolling stock to cool the rolls and strip to lubricate the joint and to permit roller and belt cleaning. These fluids are commonly referred to as cooling lubricants (KSS).
  • KSS cooling lubricants
  • the cooling lubricants In the case of the cooling function of rollers and belt, the cooling lubricants, especially during cold rolling, serve to dissipate the forming heat and the frictional heat. In the function of the lubrication of the active joint in the roll gap, the cooling lubricants are used to adjust the tribological conditions in the roll gap suitable and thus to ensure a corresponding surface quality of the rolled rolled material. With regard to the cleaning function, the cooling lubricants are used to clean the roller and the rolling stock and to remove dirt particles in order to achieve a good surface quality of the rolled strip.
  • the cooling lubricants can have an influence on the conditioning of the belt.
  • the coolants are also adjusted to be compatible with the upstream and downstream equipment within the process chain in the processing of the rolling stock, for example with regard to corrosion protection, cleaning in other process steps and / or avoiding discoloration of the rolled strip, for example, during annealing of the rolling stock. It is also desirable that the properties of the cooling lubricant remain substantially stable during use and no degradation takes place over time.
  • cooling lubricants which are used either as single-phase oil-based coolants or water-based coolants with dispersed oil-based droplets which are then present as emulsions.
  • the purely oil-based cooling lubricants have the disadvantage of water-based systems, the disadvantage of flammability and a poorer heat transfer and a low heat capacity. As a result, the productivity of such operated rolling plants is relatively limited.
  • Emulsions can have disadvantages in that the oil-based droplets within the emulsion first have to settle on the respective rolling surfaces or rolling-surface surfaces, so that the lubricant-active substances contained in them and the higher viscosity of the oil phase have an effect. Before entering the nip of the nip, separation of the continuous phase from the tribologically active substance is desired. This results in a delay of the effect, which either a limit of the rolling speed is achieved, or the distances between the stands must be made longer in order to achieve the required exposure time.
  • the terms "ultrafine filtration” or “ultra-fine filtration” are used to clarify that, in contrast to filtration and fine filtration, also that part of the particle spectrum is detected whose maximum longitudinal extent of a single particle is less than 5 ⁇ m.
  • Dirt particles which are smaller or equal to the order of magnitude of the oil droplets in the emulsion can not be removed from the cooling lubricant without at the same time discharging the oil phase from the cooling lubricant.
  • the properties of dispersed oil-based droplets based on water-based cooling lubricants can be degraded by mechanical, biological or chemical action.
  • degradation is used to simplify, if a detrimental change of a product property is referred to, without describing the mechanism underlying the change closer and without restrictive reference to the scientific classification in terms of physical, chemical, procedural, physiological, olfactory or any other product feature.
  • German Offenlegungsschrift discloses DE 101 43 407 A1 a method and a plant for cold rolling of strips, among others made of stainless steels.
  • the plant is a multi-stand tandem mill, with the first scaffolds driving comparatively high decreases and the last scaffolding determining the surface quality of the strip with a relatively small decrease.
  • the cooling lubricant used is an emulsion for which no ultrafine filtration is provided.
  • rolling oil is used as the lubricant on the last stand of the tandem mill with a relatively small reduction, and this rolling oil is microfiltered to ensure a high surface quality.
  • the British patent publication GB 729,615 on which the preambles of claims 1 and 11 are based, also a method and a system for rolling rolling, wherein a water-based cooling lubricant material is applied to the rolling stock and / or on at least one of the work rolls.
  • the water-based cooling lubricant is enriched before application with a water-soluble and tribologically active additive and the enriched coolant is collected in the outlet of a rolling stand, to be subsequently reused, ie reapplied.
  • the invention has the object of developing a known method and a known apparatus for rolling rolling to the effect that the surface quality of the rolled rolled material is further increased.
  • a method for rolling rolling stock whereby a water-based cooling lubricant is applied to the rolling stock and / or to at least one roll forming a roll gap.
  • at least one water-soluble additive which modifies the viscosity and also the lubricating properties in the active joint during the forming process is added to the water-based coolant lubricant prior to application to the rolling stock and / or the at least one roller, hereinafter referred to as "tribologically active" additive.
  • the use of the water-soluble and tribologically active additive in comparison with the use of oil-based cooling lubricants achieved that for certain applications, such as the high-speed rolling of aluminum and viscosity ranges can be used that are not available when using oil-based cooling lubricants or not feasible under industrial manufacturing conditions , This applies in particular to substances with a kinematic viscosity below 1.8 mm 2 / s at 40 ° C.
  • the cooling lubricant can be adapted accordingly to the respective individual rolling case, that is, for example, to the processed rolling stock or rolling material and the rolling conditions in the rolling gap.
  • the water-based coolant is applied together with the water-soluble and tribologically active additive depending on the rolling case on the rolling stock and / or on the roller gap forming rollers, preferably by adjusting the order conditions, particularly preferably by changing the flow temperature, the application pressure, the type of application , as well as the place of application. Accordingly, a certain concentration or layer thickness of the water-soluble and tribologically active additive is achieved on the rolling stock and / or on the corresponding roll (s) in order to be able to set the corresponding tribological conditions in the roll gap.
  • cooling lubricant circuit In order to form a cooling lubricant circuit effectively, excess cooling lubricant is collected after application to the rolling stock and / or the roll, then subjected to ultrafine filtration, and then the finely filtered coolant used again as a cooling lubricant for application to the rolling stock and / or the roll.
