Definitions
- the invention relates to a method for producing a strip from aluminum or from an aluminum alloy with a textured surface, a cold-rolled strip being passed through the nip of two texturing rollers provided with a roughness pattern and the roughness pattern under one of the texturing rollers acting on the strip Force is transferred to the belt surface.
- the invention further relates to a system for producing a cold-rolled strip from aluminum or from an aluminum alloy with a textured surface, with a cold rolling mill.
- strips and sheets made of aluminum alloys are used to manufacture body parts, whereby the sheets are formed, for example, by deep drawing or stretch drawing.
- Lubricants must be used to carry out these deep-drawing and other forming processes.
- a pre-coating of the strips or the sheets in the rolling mill not only simplifies the workflow during the forming process, it also provides optimal transport protection.
- the cold-rolled strip is coated with an oil or a water-soluble dry lubricant at the strip manufacturer and supplied to the sheet metal processor as a pre-assembled strip for deep drawing.
- the lubricants show a relatively poor quality on the surface of an aluminum strip produced in a conventional manner over work rolls with a roll cut corresponding to a mill finish surface texture Liability and distribution.
- the adhesion and distribution properties of dry lubricants on the belt surface can be significantly improved by applying a roughness pattern to the belt surface.
- the sheet surface is roughened over the correspondingly roughened surface of the work rolls by transferring the roughness pattern when the strip is cold rolled.
- the roughness patterns applied today to improve the adhesion and the distribution of a dry lubricant on the surface of an aluminum strip are generated by work rolls, for example with the spark erosion process (EDT - Electrical Discharge Texturing), the electron beam process (EBT - Electron Beam Texturing) or the PRETEX process has been roughened. All of these roughening processes lead to a surface texture with randomly distributed, closed “lubricant pockets”.
- the above-mentioned roughness patterns are transferred to the strip surface with a small pass reduction of approximately 0.05 to 15% in an additional cold rolling pass.
- this additional cold rolling pass is associated with correspondingly increased production costs.
- the work rolls provided with a conventional roll grinding must be exchanged for the texturing rolls.
- the invention has for its object to provide a method and a system of the type mentioned, with which the production costs can be reduced in the production of textured tapes. Another goal is to reduce the loss of capacity of a production plant due to the additional texturing stitch.
- the solution according to the invention with regard to the method is that the cold-rolled strip passes immediately after it emerges from a cold rolling mill the nip of the two texturing rollers and the textured tape is wound up.
- the cold-rolled strip is drawn through the nip and the texturing rolls are towed off the strip by the pulling process.
- the texturing rolls are towed off the strip by the pulling process.
- the texturing rollers are preferably set to a constant roller force.
- the texturing rollers are preferably roughened by the spark erosion method (EDT - Electrical Discharge Texturing).
- the method according to the invention is also suitable for smoothing cold-rolled strips.
- the rollers are only ground over their circumferential direction, ie the roller grinding consists of a large number of parallel, grooves distributed over the circumference of the work rolls.
- a texturing roller with texturing rollers is arranged immediately after the cold rolling mill in the strip running direction.
- the texturing rollers can be connected to a drive unit.
- An arrangement is preferred in which the texturing rolls in the texturing mill are supported by intermediate rolls and the intermediate rolls are supported by support rollers.
- the support rollers can be arranged in several sets across the width of the intermediate rollers.
- the support rollers are preferably operatively connected to hydraulic cylinders controlled by constant force.
- the texturing mill can be built into the frame of the cold rolling mill.
- FIG. 1 is a side view of a system for producing a tape with a textured surface.
- FIG. 2 shows the front view of a texturing roll mill
- - Fig. 3 shows the cross section through the roller arrangement of the rolling mill of
- a system shown in FIG. 1 for producing an aluminum strip with a textured surface comprises a cold rolling mill 17 with two work rolls 18, 20 forming a roll gap 19 and two support rolls 22, 24 supporting the work rolls.
- the work rolls 18, 20 and the support rolls 22, 24 are arranged in a stand 26 in a known manner.
- a texturing mill 28 which is smaller than the cold rolling mill 17.
- the texturing mill 28 has two one Roller gap 39 delimiting texturing rollers 38, 40, which are supported by a pair of intermediate rollers 42, 44. Each pair of intermediate rollers 42, 44 is supported by five sets of three support rollers 46, 48.
- the support rollers 46, 48 are supported in beams 50, 52 which extend across the width of the roller.
- the upper bar 50 is supported by hydraulic pressure cylinders 58 with respect to an upper frame part 54, the lower bar 52 lies directly on a lower frame part 56.
- the two frame parts 54, 56 can via hydraulic lifting or.
- Countersink cylinders 60, 62 are moved towards and away from one another, ie the roller gap 39 can be opened as required if no texturing step is required, or adjusted to the dimension required for a texturing stitch.
- the roller force is adjusted via the hydraulic pressure cylinders 58 and thus the reduction in thickness on the strip is determined during texturing.
- a cold-rolled strip wound on a supply roll 14 is fed horizontally to the nip 19 of the cold rolling mill 17 after deflection via a deflection roller 16 in the direction of strip travel x.
- the strip 12 After exiting the nip 19, the strip 12 enters the nip 39 of the texturing mill 28.
- the strip 12 After exiting the texturing mill 28, the strip 12 is steered around two further deflection rollers 30, 32 and wound up on a reel 34.
- the strip thickness is checked between the texturing roller mill 28 and the second deflection roller 30 by means of a thickness measuring device 36.
- the second deflection roller 30 also serves to check the flatness of the textured belt 12.
- the work rolls 18, 20 of the cold rolling mill 17 are driven and the strip 12 is drawn into the roll gap 19 by the rolls themselves.
- the texturing rolls can be actively driven or not driven. If the texturing rollers 38, 40 are not driven, the belt 12 must be pulled through the texturing roller 28. This takes place via the driven reel 34.
- the braking effect of the texturing rollers 38, 40 leads to a tension-regulating effect, which leads to an improved flatness of the textured Volume 12 leads.
- the diameter of the texturing rollers 38, 40 is of course smaller than the diameter of the driven work rollers 18, 20 of the cold rolling mill 17. This leads to an improved texture in the strip surface, so that less stitch reduction is required.
- the diameter of a texturing roller is, for example, about 350 mm.

Abstract
L'invention concerne un procédé de production d'une bande d'aluminium ou d'un alliage d'aluminium ayant une surface texturée. Selon ce procédé, une bande laminée à froid (12) passe, dès sa sortie d'un laminoir à froid (17), entre deux cylindres à texturer dotés d'un motif de rugosité. Puis la bande texturée (12) est enroulée. Le motif de rugosité est transféré à la surface de la bande par une force exercée par le cylindre à texturer sur la bande (12). Dans le cas d'une installation de production d'une bande d'aluminium ou d'un alliage d'aluminium laminée à froid et ayant une surface texturée, un laminoir à texturer (28) comprend des cylindres à texturer est implanté immédiatement en aval du laminoir à froid (17) dans le sens de défilement de la bande (x). Ce procédé et cette installation rendent superflue une passe à texturer distincte et donc, par rapport au procédé selon l'état de la technique, une passe de laminage.
