Definitions

  • the invention relates to a method and apparatus for cooling and / or lubrication of rolls and / or rolling, in which from a plurality of nozzles / rows of nozzles on the one hand a cooling medium on the rollers and for lubrication on the other hand, a base oil is applied to the rolling stock before the nip, wherein the nozzles / nozzle rows can be adjusted individually and independently of each other.
  • a hot rolling process and a hot rolling mill for metal strip have become known from one or more rolling mills.
  • a cooling liquid is sprayed in a narrow area extending immediately in front of the nip, with both the jackets of the work rolls and the metal strip being acted upon.
  • the temperature at the surface of the jackets of the work rolls is adjusted so that at least immediately before the nip, a temperature is reached, which is below the boiling temperature of the cooling liquid.
  • a method and a device are known in which the concentration of an emulsion of rolling oil is influenced in a targeted manner and the emulsion or dispersion is collected and separated again after it has left the nip or, respectively, before it leaves the nip.
  • the focus of this solution lies in the current production of the emulsion and the separation of the media involved.
  • EP 0 794 023 A2 shows a device and describes a method in which a lubricant, separated from water, obliquely applied in the nip and directly to a rolling stock.
  • a lubricant separated from water, obliquely applied in the nip and directly to a rolling stock.
  • FIGS. 1 to 4 is shown and explained in the description that the Schierstoff comes into contact with the cooling water and mixed with it and washed off. This mixture must then be collected and separated. For this purpose, several tanks and separation devices are necessary.
  • JP 59 169 608 A It is known that a mineral oil is sprayed during hot rolling on the surfaces of the work rolls, the cooling water was previously removed from these surfaces.
  • a lubricant is sprayed by means of nozzles 3 directly to the work rolls 1 and through further nozzles 3 directly to the support rollers 2. Since both the work rolls and the backup rolls are loaded with a lubricant, an increased use of lubricant is necessary in order to comply with the required rolling properties during hot rolling.
  • the known cooling and / or lubricating methods or devices have in common that in the applied emulsions of the lubricating film, consisting of the carrier medium water and the actual lubricating shares (additive or oil) does not arrive effectively in the nip.
  • the lubricating film consisting of the carrier medium water and the actual lubricating shares (additive or oil) does not arrive effectively in the nip.
  • additive or oil additive or oil
  • the invention is therefore an object of the invention to provide a method and an apparatus of the type mentioned without the disadvantages mentioned and in particular to achieve significantly improved lubrication in the nip and to minimize consumption.
  • the invention is based on the surprising finding confirmed by numerous experiments that with the direct application of exclusively the lubricating additive or oil, which is used sealed or separated from the cooling medium, the lubricating additive unfolds its full effect in the roll gap.
  • a proposal of the invention provides that the base oil is applied to the inlet side on the top and / or on the underside of the preferably cold-rolled rolling stock. Both top and bottom application may be appropriate depending on the material properties of the rolling stock.
  • cooling medium is advantageously applied to the rolls both on the inlet side and outlet side, washing of the work rolls can be achieved simultaneously with the strip cooling, even before the rolls have completed their rotation to the inlet side. As it turns out, not only the service life of the work rolls is substantially increased, but in addition to almost sparkling bare rolls and the Walzgutober perennial be much cleaner.
  • a media barrier for example, between the nozzle / nozzle rows for applying the cooling medium to the rollers and the nozzle / nozzle rows for applying the base oil to the rolling stock.
  • a seal in the form of a bulkhead arranged. The cooling medium is thereby kept safe from the oil or additive remotely or separately, so that the applied directly to the rolling surface additive / oil can not be washed off.
  • a base oil nozzle / nozzle row arrangement is directed vertically onto the surface of the rolling stock and another base oil nozzle / nozzle row arrangement obliquely into the roll gap.
  • the manufacturing and assembly costs can be limited.
  • the nozzles / nozzle rows can be set independently of one another or subjected to different pressures.
  • coolant nozzles / rows of nozzles arranged on the outlet side can advantageously also be directed onto the rollers.
  • the single figure shows a side view of a roller assembly according to the invention with nozzles / nozzle rows for the rolling stock, the nip and the rollers.
  • a rolling stock 3 is rolled in the direction of passage indicated by the arrow 4; the rolling stock or strip 3 is deformed in the nip 15 between the work rolls 1, 2.
  • nozzles / nozzle rows 7, 7 'and 8, 8' or 9, 9 'are arranged, of which the nozzles / nozzle rows 9, 9' are not shown Apply supply source supplied cooling medium to the surface of the work rolls 1, 2.
  • the nozzles / nozzle rows 7, 7 ', 8', 8 'or 9, 9' arranged in the exemplary embodiment in nozzle bars 14, 14 ' can be acted upon separately and set independently of one another and subjected to different pressures.
  • the obliquely directed to the nip 15 additive / Oil nozzles / nozzle rows 8, 8 'with a pressure of 2 to 7 bar and the large amount of the cooling medium on the work rolls 1, 2 applying nozzles / nozzle rows 9, 9' are supplied with a pressure of 2 to 10 bar.
  • the large amount of cooling medium is held separated by the in the embodiment as a bulkhead 12, 12 'formed seal of the small amount of additive / oil, which thus fully effective in the nip 15 reaches the deployment.
