Definitions

  • the invention relates generally to the technical field of rolling a metal rolling stock, in particular a rolling led in a nip between two work rolls, wherein a lubricant is used for the purpose of lubrication.
  • liquid or gaseous treatment media are used in the rolling of metallic rolling stock, for example a metal strip, for the purpose of lubrication and cooling.
  • These treatment media are different depending on the type of rolling process: in hot rolling, in which the rolling stock is heated to several 100 ° C, a water-oil emulsion is usually used; during cold rolling, in which the temperature of the rolling stock is usually below 100 ° C. before the rolling process, the lubrication in the roll gap is usually carried out by a cold rolling oil, wherein a cooling liquid is additionally used.
  • the invention is based on the object to provide a method and apparatus for applying a lubricant when rolling a metallic rolling stock, in which the lubricant consumption is minimized.
  • the medium used for roller gap lubrication is not a rolling fluid but a spray, that is to say a mixture of rolling oil and a carrier gas.
  • the lubricant is divided into finely distributed liquid droplets in an atomizer and introduced into the roll gap by means of the carrier gas. This application or introduction into the roll gap can take place either by spraying onto the surface of the work rolls, and / or onto the surface of the rolling stock entering the roll gap. Due to the homogeneous application of the lubricant as a spray, the lubricant consumption can be kept comparatively low.
  • the present in droplet form of lubricant very selectively wets only those areas of the surface of work roll and / or rolling, which are decisive for the friction during rolling.
  • the decisive factor is merely that a sufficient amount of oil for lubrication reaches the nip; this can in principle be achieved by spraying on the surface of the work rolls or on the surface of the incoming rolled strip, or on both surfaces.
  • the concentration of the lubricant in the nip is significantly higher. This increases the efficiency of the lubricant used, because just as much rolling oil passes into the rolling gap as required depending on the type of rolling stock to reduce friction in the nip is.
  • the invention Seen in the width direction of the rolled strip, the invention enables a uniform application of the lubricant. This reduces the risk that set in the nip in the width direction different friction conditions.
  • spray nozzles which are arranged in a row and in each case produce a spray jet which is essentially flat when viewed in cross-section.
  • the individual cross sections can overlap in the edge area.
  • a fan-shaped overall spray can be generated, with which the lubricant can be introduced homogeneously and selectively into the roll gap.
  • spray nozzles which have at least two outlet openings. Depending on the shape of these at least two outlet openings, it is very easy to achieve a uniform surface concentration of the lubricant during application.
  • nozzles that are spherical have curved mouthpiece.
  • two symmetrical C-shaped slots are provided with respect to an axis of symmetry.
  • a spray can be formed with a comparatively small number of nozzles, which applies the lubricant evenly.
  • the cross section of these spray jets can be influenced.
  • the spray is formed from a juxtaposition of individual spray jets, each of these spray jets being directed in its width direction approximately parallel to the axis of the two work rolls.
  • a carrier medium for the lubricant droplets can be used in a simple embodiment of the process air.
  • FIG. 1 shows in a highly simplified representation of a vertical section through a roll stand.
  • the rolling stand consists essentially of the two work rolls 2 'and 2'', and the respective support rollers 3' and 3 ''.
  • a rolled strip 28 is passed from left to right in the direction indicated by the arrow between the two work rolls 2 'and 2 "in the roll gap 8.
  • the device 1 according to the invention is sketched at the top and bottom of the rolled strip 28 on the inlet side Rolling oil sprayed in the direction of the roll gap 8.
  • the atomization of the rolling oil takes place in each case in a atomizing device 4, which is supplied via lines 6 and 7 rolling oil or air.
  • a mixture of air and lubricant particles is formed, which is applied by means of an array of spray nozzles 5 as a spray.
  • This spray is deposited on the surface 21 of the work rolls 2 'and 2' 'and / or on the surface 23 of the rolled strip 28, whereby the desired reduction in the friction conditions in the nip 8 is effected.
  • rolling oil is collected together with the coolant and recycled by means of a conveying and reprocessing plant.
  • FIG. 2 shows an array of spray nozzles 5 on a spray bar 13.
  • Each spray nozzle 5 is fed via a first line 6 rolling oil and via a second line 7 air.
  • Each spray nozzle 5 generates a spray jet 9, which is formed flat in cross section 15 seen. The juxtaposition of these individual flat spray jets 9 forms a total with respect to the oil concentration total spray 19th
  • FIG. 3 shows a cross-sectional view of the atomizing device 4.
  • this atomizing device 4 is supplied via a connecting line 6 rolling oil and via another connecting line 7 air.
  • the generation of the oil-air mixture takes place in a manner known per se: In a swirling chamber 31, the two media air 27 and oil 26 meet.
  • the air 27, which flows at high speed past an orifice of the rolling oil feed 6, entrains oil particles 26, so that a mixture of air and finely divided oil-liquid droplets forms in the swirling chamber 31. Size and design of these liquid droplets can be adjusted in each case by the amount of media supplied and by blending in a wide range.
  • These diaphragms in the inlet of air and oil are interchangeable in the atomizer 4.
  • This mixture is fed via a short connector of a spray nozzle 5.
  • the spray nozzle 5 is spherically curved in the region of an orifice 18.
  • two outlet openings 10 are formed in the area of the spherical curvature 12.
  • Each of these outlet openings 10 is formed by a slot in the region of the mouth 18. The preparation of this slot in the spherical curvature 10 can be easily done by a cut with a saw blade.
  • FIG. 4 shows two views of the mouthpiece 18: in the upper view, the mouthpiece 18 is shown in a sectional view, in the lower view in a three-dimensional view.
  • the mouthpiece 18 is convexly curved outwards.
  • the curvature 12 is a circular arc.
  • a corresponding curvature is also formed on the inner wall of the mouthpiece 18.
  • two outlet openings 10 formed by cuts for the mixture are to be seen, which - seen in a direction opposite to the outflow direction - each have the shape of a "C".
  • the arrangement of these two C-shaped outlet openings 10 is chosen so that the legs 25 of the two "C" from an axis of symmetry 11 point away.
  • the two incisions "C" are back-to-back.
  • the production of these outlet openings 10 is effected by cuts.
  • the planes of the incisions 10 are at an angle 30 to each other.
  • the slot width 14 of these cuts is advantageously between about 0.6 to 0.7 mm.
  • FIG. 5 illustrates in a highly simplified representation of the lubrication in the nip
  • the upper diagram shows the lubrication with emulsion according to the state of Technique
  • the lower illustration represents the inventive application of the rolling oil by means of a spray.
  • the lubricant concentration in the nip 8 is lower than in the introduction of the lubricant in the form of a spray, which is in the lower illustration of the FIG. 5 is illustrated.
  • a higher concentration of lubricant forms in the nip 8 compared to emulsion lubrication.
  • a comparatively low oil consumption of 50 ml per minute to 200 ml per minute per rolling mill can be achieved.
  • Another advantage results from the greatly reduced friction in the nip, whereby the rolling forces and rolling moments for the rolling process can be reduced. Especially during cold rolling, a very good surface quality of the rolled strip can be achieved.
