Definitions

  • the invention relates to a method for producing a strip from aluminum or of an aluminum alloy with a textured surface, wherein a cold rolled strip through the nip of two with a roughness pattern provided texturing rollers and the roughness pattern underneath a force exerted by the texturing rollers on the belt on the belt surface is transmitted.
  • the invention further relates to a plant for production a cold rolled strip made of aluminum or an aluminum alloy with a textured surface, with a cold rolling mill.
  • strips and sheets are made of aluminum alloys used for the production of body parts, the sheets for example are formed by deep drawing or stretch drawing. to Must carry out these deep-drawing as well as other forming processes Lubricants are used.
  • Lubricants are used.
  • the cold rolled strip is made by the strip manufacturer coated with an oil or a water-soluble dry lubricant and as a pre-assembled strip for deep drawing to the sheet metal worker delivered.
  • the adhesion and distribution properties of dry lubricants on the The belt surface can be applied to the surface by applying a roughness pattern Improve the belt surface significantly.
  • the roughness patterns mentioned are today with a small decrease in stitch from about 0.05 to 15% in an additional cold rolling pass on the strip surface transfer. In practice, this additional cold rolling pass is also appropriate associated with increased production costs.
  • to apply of the roughness pattern are each provided with a conventional roller cut Work rolls are exchanged for the texturing rolls.
  • the invention has for its object a method and a system of to create the kind mentioned at the outset, with which the production costs at Production of textured tapes can be reduced. Another goal is the loss of capacity caused by the additional texturing stitch Reduce production facility.
  • the solution according to the invention with regard to the method is that it is cold rolled strip immediately after emerging from a cold rolling mill the nip of the two texturing rollers and the textured belt is coiled up.
  • the cold rolled strip is drawn through the nip and the texturing rollers are towed off the conveyor by the pulling process. It goes without saying it is also possible to actively drive the texturing rollers.
  • the texturing rollers are preferably set to a constant roller force.
  • the texturing rollers are preferably a dry lubricant after EDM (Electrical Discharge Texturing) roughened.
  • the method according to the invention can also be used for smoothing cold rolled strips is suitable.
  • it can prove to be beneficial prove the texturing rollers with the usual today, to the surface quality "Millfinish" to provide leading simple roll grinding of work rolls.
  • the rollers are only ground along their circumferential direction, i.e. the Roll grinding consists of a variety of parallel, across the circumference of the Distributed groove work rolls.
  • a texturing mill is arranged with texturing rollers.
  • the texturing rollers can with a drive unit be connected.
  • the texturing rollers in the texturing roller mill are supported by intermediate rollers and the intermediate rollers by support rollers.
  • the Support rollers can be arranged in several sets across the width of the intermediate rollers his.
  • the support rollers are preferably with hydraulic ones controlled by constant force Cylinders in operative connection.
  • the texturing mill can be built into the stand of the cold rolling mill.
  • a system shown in Fig. 1 for producing an aluminum strip with a Textured surface comprises a cold rolling mill 17 with two one roll nip 19 forming work rolls 18, 20 and two supporting the work rolls Back-up rolls 22, 24.
  • the work rolls 18, 20 and the backup rolls 22, 24 are arranged in a frame 26 in a known manner.
  • the texturing mill 28 has two one Roller gap 39 texturing rollers 38.40, each of a pair Intermediate rollers 42, 44 are supported. Each pair of intermediate rolls 42, 44 is supported by five sets of three support rollers 46, 48 each.
  • the support rollers 46, 48 store in bars 50, 52 which extend across the roll width.
  • the upper Beam 50 is via hydraulic pressure cylinder 58 opposite an upper one Supported frame part 54
  • the lower bar 52 is a lower frame part 56 directly on.
  • the two frame parts 54, 56 can be lifted by hydraulic or lowering cylinders 60, 62 are moved towards and away from one another, i.e. the roller gap 39 can be opened as required, if none Texturing step is required, or to that required for a texturing stitch Dimension can be set.
  • About the hydraulic pressure cylinder 58 Rolling force adjusted and thus the decrease in thickness on the belt during the Texturing set.
  • a surface texture To apply a surface texture, one is wound on a supply roll 14 cold rolled strip after deflection via a deflection roller 16 horizontally in the direction of strip travel x the nip 19 of the cold rolling mill 17th fed. After emerging from the nip 19, the belt 12 enters the Roll gap 39 of the texturing mill 28. After leaving the The texturing mill 28 turns the strip 12 around two further deflection rollers 30, 32 steered and wound on a reel 34. Between the texturing mill 28 and the second deflection roller 30 is the thickness measuring device 36 Checked strip thickness. The second deflection roller 30 serves at the same time, the Check the flatness of the textured tape 12.
  • the work rolls 18, 20 of the cold rolling mill 17 are driven and the feed of the belt 12 in the nip 19 is carried out by the rollers themselves Texturing rollers can be actively driven or not driven. Are the Texturing rollers 38, 40 are not driven, the belt 12 must pass through the Texturing mill 28 are pulled. This is done via the driven Reel 34. The braking effect of the texturing rollers 38, 40 leads to a tension regulating Effect that leads to improved flatness of the textured Volume 12 leads.
  • the diameter of the texturing rollers 38.40 is naturally smaller than that Diameter of the driven work rolls 18, 20 of the cold rolling mill 17th This leads to an improved texture in the belt surface, so that a less stitch acceptance is required.
  • the diameter of a texturing roller is, for example, about 350 mm.
