Definitions

  • the invention relates to a skin work roll with a surface structure, a method for skin dressing a flat product from a metal material, in particular from a steel material, with a skin work roll and a flat product made from this metal material, in particular from a steel material.
  • the thin steel sheets used as body panels are cold-rolled before painting.
  • This cold rolling is also known as skin-pass finishing.
  • Cold re-rolling is used to set the mechanical parameters such as yield strength, tensile strength and elongation as well as the surface topography, for example characterized by the roughness, number of points and corrugation of the thin steel sheet, to a desired condition.
  • Steel sheet metal treated in this way with a defined surface topography simplifies the subsequent painting process by avoiding or reducing the application of filler layers.
  • These filler layers are used in particular to compensate for any unevenness on the surface of the thin steel sheet to be painted and thus to prevent these unevenness from becoming apparent in the painted surface.
  • Skin pass work rolls with a profiled surface are used for the cold rolling process.
  • the surface is profiled from a roller with a smoothly ground surface using various texturing processes. Through the cold rolling process with appropriate The skin-pass mill is then textured on the surface of the thin steel sheet. The same applies in general to thin steel sheets outside the area of the body sheets.
  • ablation texturing processes for skin pass work rolls SBT (Shot Blast) - spinning angular blasting material onto the surface of the skin pass work rolls, EDT (Electro Discharge Texturing) - spark erosion, EBT (Electro Beam Texturing) - electron beam in a vacuum shoots defined craters into the surface of the skin pass work rolls, Lasertex - laser beam shoots defined craters into the surface of the skin pass work rolls.
  • a textured sheet is known for the highest demands in body construction.
  • This thin sheet can be uncoated or surface-coated and is used by the automotive industry in body construction for inner and outer skin parts with the highest demands on forming behavior and paintability.
  • the surface topography of the thin sheet significantly influences the forming behavior as well as the adhesion and the optical properties of the automotive coating.
  • a defined surface topography of the thin sheet corresponding to customer requirements is generated during cold rolling.
  • the skin pass work rolls used for this purpose are produced in a positive process by applying a texture to a smooth roll.
  • a so-called TOPOCROM® process is particularly suitable for this, with which the surface of a smooth roller is electrolytically chromium-plated and hard-chromed.
  • the skin pass work roll is coated in a reactor which is equipped with an anode cage and is filled with a chromium electrolyte.
  • the chromium ions of the electrolyte are reduced during the coating and metallically deposited on the surface of the skin pass work roll.
  • This coating process provides an absolutely uniform stochastic distribution of the different sized hard chrome hemispheres deposited on the roller surface, the size and number of which per unit area can be set in a targeted and reproducible manner by means of the process computer-controlled coating parameters according to customer requirements.
  • the hard chrome hemispheres of the skin pass work rolls are opened up in the form of appropriate calottes transfer the thin sheet.
  • the surface topography of the thin sheet has the task of absorbing the lubricant and supporting hydrostatic or hydrodynamic lubrication to reduce friction.
  • a higher average roughness value and lubrication pockets that are insulated from one another and serve as a lubricant reservoir significantly improve the friction and lubrication conditions.
  • An improvement of the paintability with a simultaneous reduction of the paint system layer thicknesses is achieved by high peak numbers as well as low long-wave (short wave) and short-wave structural components. Longer-wave structural components can cause the orange peel in the top coat of painted automotive sheet metal.
  • a corresponding roller for producing such a flat product should have a surface structure which is characterized by a peak number RPc in the range from 80 to 180 1 / cm, an arithmetic mean roughness Ra in the range from 2.5 to 3.5 ⁇ m and an arithmetic mean ripple Wsa in the range from 0.08 to 1.0 ⁇ m.
  • the smooth portion of the roller in the sense of a non-textured area is about 25%.
  • the European patent application EP 0 606 473 A1 describes a roller with a laser-textured surface structure for the dressing of steel sheets.
  • the surface structure of the roller has a large number of protruding hemispheres made of chrome, which are transferred to the steel sheet from 40 to 100% during the skin pass. This creates impressions with a diameter d of 50 to 500 ⁇ m and a height h of 2 to 40 ⁇ m in the steel sheet. The distance between the individual impressions is between 1.0 d and 4.0 d.
  • the translation of the European patent specification DE 694 23 784 T2 describes a method for structuring the surface of a work roll using an electron beam.
  • the structured surface consists of a two-dimensional, determined pattern of points. Each point has the shape of a crater with a predetermined edge. After structuring, the roll surface has a roughness Ra between 0.4 to 8.0 ⁇ m.
  • the invention is based on the object of an improved skin-pass work roll with a surface structure, an improved method for skin-dressing a flat product made of a metal material, in particular made of a steel material, with a skin-pass work roll and an improved flat product made of a metal material, in particular made of a material, produced by this method To create steel material.
  • an improved skin work roll in particular for the production of flat products from a metal material, in particular from a steel material, with a surface structure
  • the surface structure has a material content of 2% at a depth of 0.2 ⁇ m to 9 ⁇ m, preferably in one Depth from 0.8 ⁇ m to 5.5 ⁇ m, the depth is measured starting from a zero line in the direction of an axis of rotation of the skin pass work roll, the zero line is parallel to the axis of rotation of the skin pass work roll and the zero line is starting from the surface of the skin pass work roll in the direction of The axis of rotation of the skin pass work roll has been shifted until its material content is 0.1%.
  • the surface structure of the skin pass work roll thus has a low proportion of material, so that during the skin pass the greatest possible ratio between the topography change of a flat product to be dressed and an extension of the flat product is achieved.
  • the small proportion of material can also be determined by the fact that the surface structure has a proportion of 5% material at a depth of 0.7 ⁇ m to 12 ⁇ m, preferably at a depth of 1.1 ⁇ m to 6.5 ⁇ m.
  • a further determination of the material content results from the fact that the surface structure has a material content of 10% at a depth of 1.0 ⁇ m to 15 ⁇ m, preferably at a depth of 1.4 ⁇ m to 7.4 ⁇ m.
  • the surface structure of the skin pass work roll is electrolytically structure and hard chrome plated.
  • a method for skin-dressing a flat product from a metal material, in particular from a steel material is improved in that the flat product is rolled with the skin-pass work roll according to the invention.
  • the flat product is advantageously rolled with a skin pass degree in the range from 0.1 to 2.0%.
  • the thickness of the flat product is in the range from 0.35 to 2.0 mm.
  • the flat product can preferably be provided with coatings of zinc or a zinc-aluminum alloy or a zinc-iron alloy or zinc-aluminum-magnesium alloy.
  • the flat products produced in connection with the invention are preferably used in motor vehicles, household appliances - so-called white goods - and sheet steel furniture.
  • the flat products can be galvanized or hot-dip galvanized.
  • the flat products can also be formed into components by, for example, deep drawing and stretch drawing.
  • the flat products are preferably intended for later painting and are used as coated visible parts.
  • the flat products are particularly suitable for forming processes, especially deep drawing.
  • flat products are to be understood as sheets, in particular thin sheets, which are produced from metal, metal alloys, in particular steel.
  • the resistance that the flat product offers to the topography change must be compensated for during the skin pass process.
  • the surface structure of the skin pass work rolls is pressed in deeper than the impression that remains in the surface of the flat product after the pressure has been released. Due to this material-dependent springback, surface structures of skin pass work rolls with a lower material content have a particularly positive effect when processing flat products with high deformation resistance.
  • Flat products with soft metallic coatings also enable better transfer of the surface structure of the skin pass work roll than firmer, uncoated flat products, for example made of steel.
  • FIG. 1 is a Cartesian coordinate system shown with a depth in ⁇ m of about 15 to 0 ⁇ m as the y-axis and a material fraction of about 0 to about 10% as the x-axis.
  • the percentage of material describes the presence of material of the skin pass work roll within a surface which is representative of the entire upper peripheral surface of the skin pass work roll. A proportion of roughness valleys could therefore be viewed as the opposite of the percentage of material.
  • the proportionate material in the surface is determined with a 3D measurement starting from the surface in the direction of a central axis of rotation of the roller. The 3D measurement is based on a representative surface of approximately 2.5 mm 2 . The The percentages of material determined in 3D measurement are then based on the surface of the skin pass work roll at a depth specified in ⁇ m. The material proportions can be determined from the roughness profile of the roller.
  • the in the Figure 2 The material proportions shown have been determined based on ISO 25178 from a flat 3D roughness measurement on the corresponding rollers. So that the determined material proportions are comparable, a reference level must be defined for these measurements, from which the height and depth values are counted.
  • a zero line shift of 5% is used to create material proportion curves, ie starting from the surface of the roller in the direction of the axis of rotation of the roller. Since the roll profiles already show noticeable differences in the area of the first 5% material, a zero line shift of only 0.1% material is used here, ie the zero line for the measurement or determination of the depth in ⁇ m is only shifted until the material share is 0, 1% of the surface roughness peaks present in this area.
  • the depth in ⁇ m is now determined from the zero line in the direction of the axis of rotation of the roller. It is also in the Figure 2 specified depth averaged over the surface part of the roller and representative of the entire circumferential surface of the roller, since the dressing of the roller is uniform.
  • the Figure 2 shows an illustration of the above-described displacement of the zero line N starting radially from the surface of the skin pass work roll 1 in the direction of an axis of rotation D of the skin pass work roll 1.
  • the zero line N runs parallel to the axis of rotation D and in the area of the surface of the skin pass work roll 1.
  • the axis of rotation D runs in Direction of the longitudinal extent of the skin pass work roll 1 and centrally in the skin pass work roll 1.
  • the zero line N is shifted into schematically indicated structural elements 2 of a surface structure of the skin pass work roll 1 and radially in the direction of the axis of rotation D until the desired material proportion in relation to the structural elements 2 is 0. 1% is reached.
  • the Figure 1 shows that the exemplary course A of a skin pass work roll according to the invention, starting from the depth of 0 ⁇ m related to the 0.1% material fraction, runs very flat and only has a material fraction of 10% in the range of approximately 3.5 ⁇ m.
  • a topography results from the Topocrom® process of hard chrome hemispheres with steep flanks.
  • the ideal surface structure of a skin pass work roll for generating an intended topography of the flat product is such that it can be reproduced in the surface of the flat product before the maximum permissible belt length is reached.
  • a skin pass work roll with a surface structure according to Figure 1 comes close to an idealized structure.
  • This skin pass work roll allows a high conversion of a specific rolling force, which corresponds to a force per length of the line touching the flat product, to change the topography of the flat product and a low conversion of the specific rolling force in favor of a greater extension of the flat product.
  • a typical specific rolling force is in the range of 1.9 kN / mm.
  • the topography change can be described via the parameters roughness Ra, peak number RPc or more generally via displaced volume.
  • the extension of the flat product is expressed by the level of skin pass.
  • the degree of skin pass is generally limited by the change in the mechanical properties, the largest possible ratio between the change in topography and the elongation of the flat product is favorable in order to achieve both a slight ripple and a slight elongation of the flat product.
  • the ripple can be described using the Wsa (1-5) value according to SEP1941.
  • a minimum degree of addressing is absolutely necessary in order to achieve a desired topography change before a desired degree of skin-pass is exceeded.
  • the level of skin pass is approximately in the range of 0.1 to 2.0%.
  • a small proportion of material according to the invention on the skin pass work roll leads to a small-area distribution of the contact pressure - that is to say high local pressures - and thus primarily to a topography change instead of the elongation of the flat product.
  • the topography change results in a locally limited, lateral volume redistribution on the surface of the flat product.
  • the low material content of the skin pass work roll according to the invention has a positive effect in that it less hampers the volume redistribution than skin pass work rolls with a higher material content. Punctual accumulations of redistributed volumes on the surface of the flat product are avoided. These selective accumulations result in an undesirably high ripple Wsa (1-5) according to SEP1941.
  • the surface structures of skin pass work rolls with a low profile are preferred Material content and the surface structure that are created with processes that allow a surface structure with a large slope.
  • Such surface structures on skin work rolls can preferably be achieved using the hard chrome plating process known under Topocrom®.
  • FIG 3 schematically shows an enlarged sectional view of a surface structure of a roller according to the invention with an associated material proportion diagram.
  • the surface structure shows elevations in the form of a rectangle, a parabola and a triangle. These elevations are separated from spaces which are delimited in depth by a flat surface of the roller.
  • Figure 1 known diagram is shown with the depth over the material portion. It can be seen that, as shown in the diagram in Figure 1 is known, the material portion of the elevations is small overall and initially increases only slightly with increasing depth to a complete surface of the roller and increases sharply in the area of the maximum depth.
  • a roller with such a surface structure with a small proportion of material over the total height or total depth of the elevations preferably leads to a topography change of the dressed flat product prior to its belt extension when a flat product is tempered.
  • Use of the rollers according to the invention leads to a slight ripple in the topography of the flat product and a slight belt elongation of the flat product.
  • the Figure 4 essentially corresponds to the Figure 3 , however, the surface structure is inverse to the surface structure Figure 3 educated. Accordingly, the in Figure 3 elevations in the form of a rectangle, a parabola and a triangle, each shown by way of example, upside down the gaps.
  • the surface structure according to Figure 4 is found in conventional rollers.
  • the quality from the Figure 1 known diagram is shown with the depth over the material portion. Compared to the curve in Figure 3 it can be seen that the material proportion of the elevations is high overall and initially increases strongly with increasing depth up to a complete surface of the roller and only increases slightly in the area of the maximum depth.
  • a roller with such a surface structure with a high proportion of material over the total height or total depth of the elevations preferably leads to a belt lengthening of the flat product when it is tempered trained flat product before changing its topography. Since a band extension occurs increasingly, a topography design of the flat product will only be possible to a limited extent.
  • FIG. 5 shows a projection of a section through a flat product with the PRETEX® topography according to the invention, which was produced with a skin-pass work roll with a small proportion of material according to the invention.
  • a height or depth is in each case plotted in ⁇ m with respect to a zero line on a y axis and a length of the cut in ⁇ m is plotted on an x axis.
  • the material portion of the associated skin pass work roll determined from a 3D roughness measurement is 2% at a depth of 2.0 ⁇ m, 5% at a depth of 2.8 ⁇ m and 10% at a depth of 4.3 ⁇ m. This roughly corresponds to that in Figure 1 course drawn as A.
  • a sheet surface By using a skin pass work roll according to the invention with a low material content, a sheet surface can be achieved which, with low roughness (0.9 ⁇ m ⁇ Ra ⁇ 1.2 ⁇ m) and high number of peaks (RPc> 95 / cm), has a low waviness Wsa (1-5) less than 0.22 ⁇ m.
  • the material proportion of the sheet metal surface determined by means of a 3D roughness measurement is 2% at a depth of 1.5 ⁇ m, 5% at a depth of 2.3 ⁇ m and 10% at a depth of 2.8 ⁇ m.
