Definitions

  • the surfaces of a metal strip can be provided with the help of texturing and consequently surface texturing (i.e. surface embossing), i.e. a surface roughness is introduced into the metal strip in a targeted manner by means of skin pass and consequently rolling by the texturing of the rollers (skin pass rollers ) is transferred to the metal strip or its surfaces in the skin pass mill.
  • Metal band means within the scope of the invention preferably a metal band with a thickness of 0.5 mm to 6.5 mm, e.g. B. 0.7 mm to 4 mm.
  • the metal strip can particularly preferably be a metal strip made of aluminum or an aluminum alloy act.
  • the introduction of a surface texture increases the surface roughness of the rolled strip. This is done z.
  • the tape tension is generated by the unwinder and the rewinder.
  • the texturing of the rollers can be produced by various methods, e.g. B. as EDT texturing (electron discharge texture) or alternatively as EBT texturing (electron beam texture) or as SBT texturing (shot blast texture).
  • EDT texturing electron discharge texture
  • EBT texturing electro beam texture
  • SBT texturing shot blast texture
  • the metal strips that are provided with the surface texturing in the system are z. B. produced by rolling. Such rolled metal strips usually have oxides and dirt particles on the surface as well as a residual rolling oil film that goes back to the manufacturing process of the metal strip.
  • Such particles can stick to the skin-pass rollers during texturing by skin-pass rolling. This can lead to a build-up of particles on the rollers. During skin pass rolling or texturing, this can lead to undesired marks on the strip, which make it impossible to market the strip and thus considerably impair the economic efficiency of the process.
  • a rolling medium is applied to the strip and / or to the rollers with an application device which is arranged in front of the skin-pass stand or in the area of the skin-pass stand, e.g. B. sprayed on.
  • Such a rolling medium influences the friction conditions in the roll gap and forms a separating agent (between the belt and the roll) so that the aforementioned disturbing particles cannot clog the texturing of the rolls and consequently the roll structures so quickly. This significantly reduces the risk of the process being impaired by the disturbing particles mentioned.
  • a system for texturing the surface of a metal strip is, for. B. from the DE 10 2017 110 413 B4 known. It is proposed therein to provide a cleaning device for at least one of the work rolls of the skin pass stand which has means with which the roll surface can be at least partially brought into contact with at least one strip-shaped nonwoven during rolling. This is intended to clean the surface of the work rolls in a simple manner and to remove the roll wear on the work rolls from the roll surface.
  • the texturing of the surface of metal strips is also used in the WO 2017/095923 A1 described. It is proposed there to work with a very low degree of skin pass or a very low reduction of less than 1% and thus to produce a surface roughness on the strip in the order of magnitude of approximately 1 ⁇ m to 5 ⁇ m. This should make it possible to dispense with the addition of a rolling medium before texturing.
  • WO 2017/095923 A1 also a belt cleaning suggested for removing rolling medium prior to skin-passing. Optionally, a further belt cleaning should take place after the skin pass.
  • the invention is based on the technical problem of creating a system which, with a simple and compact structure, enables the texturing of a metal strip in an economical manner, which in particular can be further processed in a perfect manner.
  • a corresponding procedure is to be created.
  • the invention teaches in a generic system of the type described at the outset that a strip cleaning device is arranged between the skin pass stand and the winding device, with which rolling medium remaining on the strip is removed after skin pass.
  • removing the rolling medium means not only complete removal, but also partial removal and consequently a reduction in the rolling medium.
  • the invention is based on the fundamentally known knowledge that it is fundamentally advantageous to apply a rolling medium to the belt and / or to the rollers on the inlet side in order to avoid particle build-up on the rollers and that the dispensing with the use of a Rolling medium does not lead to satisfactory results.
  • the invention has recognized that a fluid film or residual fluid film remaining on the strip after skin-passing through the use of rolling medium can lead to problems in the further processing of the textured strips, in particular in the thermal treatment of such strips, e.g. B. by way of glow. If the tape z. B. subsequently annealed, e.g. B.
  • the residual fluid film in the middle of the belt can be only 30 mg / m 2 , but can be significantly larger at the belt edges, e.g. B. at 300 mg / m 2 . During subsequent annealing, this would lead to undesirable surface discoloration at the strip edges.
  • the rolling oils known from the prior art are preferably used as the rolling medium.
  • other types of rolling media with a lubricating effect can also be used, which produce the desired separating effect between belt and roller and consequently serve as a separating agent or create a separating film between belt and roller.
  • So z. B. (aromatic) solvents can also be used.
  • emulsions based on a rolling oil e.g. B. water-based rolling oil emulsions are used.
  • mixtures of the substances described can also be used, e.g. B. a mixture of a rolling oil and an (aromatic) solvent.
  • a belt connector i.e. a belt connecting device
  • the tape connector z. B. be designed as a punch connector or stitching machine.
  • a clinch connector can be used and consequently a band connector in which the metal band is connected by clinching (clinching).
  • the ribbon connector can also be designed as a welding machine or with a welding machine.
  • the invention is based on the knowledge that threading the beginning of the tape into the cleaning device can lead to problems in practice, in particular in the case of thinner tapes with residual curvature.
  • the end of the strip of the previous bundle is connected to the beginning of the strip of the following bundle in front of the skin-pass stand, so that the end of the strip on the one hand and the beginning of the strip on the other can be transported easily and reliably through the strip cleaning system without the beginning of the next coil each time must be threaded into the belt cleaning system.
  • the use of the tape connector is therefore directly related to the tape cleaning device used.
  • Such a belt connector is particularly preferably used if the belt cleaning device is designed as a high-pressure spray device which is preferably operated with hot water.
  • Such a high-pressure spray device can be very compact so that the system is characterized overall by its compact design. With such a compact high-pressure spray device, the threading of a metal strip can be particularly prone to failure, so that the use of an upstream strip connector is particularly notable in such a strip cleaning device.
  • a compact design of such a system has the advantage, among other things, that as little tape length as possible is lost through threading in or out.
  • belt cleaning devices of other types e.g. B. a belt cleaning device as a spray device or as a dipping device.
  • Water can be used as the cleaning medium in the belt cleaning device according to the invention, e.g. B. hot water.
  • cleaning agents based on water or with added cleaning agents can also be used, e.g. B. water with surfactants or alkaline or acidic cleaning agents.
  • electrolytic cleaning is also conceivable.
  • the very compact high-pressure spray device is particularly preferably used. Such a high-pressure spray device has advantages in particular in high-speed systems and consequently systems with high production capacity.
  • the alternatives mentioned require a certain treatment length, which corresponds to a certain treatment period and a certain dwell time of a few seconds at maximum speed, as well as an additional length for a subsequent rinsing with water in order to remove the residues of the cleaning agent from the belt surface.
  • Such cleanings take much longer.
  • a belt speed of maximum 300 m / min or 5 m / sec and a dwell time of 3 sec this corresponds to a cleaning distance of 15 m.
  • For the subsequent triple rinsing with 1 sec dwell time is followed by a further 15 m flushing distance, so that the total length of the cleaning is more than 30 m.
  • an overall length can be reduced to less than 15 m.
  • a high-pressure spray device as a belt cleaning device is used in particular in systems with a high production output, ie in high-speed systems. In the case of systems with lower production outputs that are operated more slowly, the belt cleaning devices mentioned as an alternative can also be used.
  • the removal of the rolling medium with the aid of the cleaning device according to the invention includes not only the complete removal of the rolling medium or the fluid film, but removal also means the (partial) removal except for a residual fluid film with a predetermined thickness of e.g. B. less than 50 mg / m 2 , preferably less than 30 mg / m 2 , preferably less than 20 mg / m 2 of the rolling medium, these details referring to the individual strip surface and consequently to each individual strip surface when exposed on both sides.
  • a dryer for drying the cleaned belt is arranged behind the belt cleaning system. This dryer is used to dry off the residual moisture after cleaning.
  • a dryer with high-pressure air knives, which is operated with warm air or hot air, is preferably used as the belt dryer. This also leads to a particularly compact design.
  • the invention works with an application of a rolling medium before skin-passing or during skin-passing, that is, the rolling medium is applied to the metal strip and / or the roller or rollers, preferably to the upper side of the belt and / or the upper roller and / or on the underside of the belt and / or the lower roller.
  • known application devices can be used. There is thus the possibility of providing an application device on the inlet side in the area of the roll gap on the upper side and / or lower side of the belt.
  • Such an application device can, for. B. be designed as a spray device with which the rolling medium is sprayed onto the belt or the respective belt surface and / or onto the respective roller.
  • pre-cleaning of the strip in front of the skin-pass stand and consequently between the unwinding device and skin-pass stand, whereby such pre-cleaning of the strip can be carried out not with water but also with a rolling medium (e.g. rolling oil or solvent or a mixture of both).
  • a rolling medium e.g. rolling oil or solvent or a mixture of both.
  • Rolling oil is pre-cleaned.
  • the spraying of the strip surface with the rolling medium and / or spraying of the rolls with a rolling medium may be omitted since this pre-cleaning of the strip is already used to apply a rolling medium and consequently a sufficient separating film is achieved, which according to the invention is removed or removed by the strip cleaning system downstream of the skin pass stand . is reduced to the required extent.
  • the invention also relates not only to a system of the type described, but also to a method for texturing the surface or the surfaces of a metal strip by means of skin passing, preferably with the system or device described.
  • the metal strip is unwound from the unwinding unit, passed through the skin-pass stand and textured in the process, and the textured metal strip is then wound up in the winding device (to form a coil).
