Definitions
- the present invention relates to a method for producing a metal sheet, in particular a steel sheet, in which at least one surface of the metal sheet is provided with a surface structure which comprises depressions and / or elevations as structural elements.
- the present invention is therefore based on the object of providing a method for producing a metal sheet of the type mentioned at the outset, which leads to a metal sheet with low sensitivity to scratching and low visibility of fingerprints.
- a microstructure is to be understood as a surface structure that is essentially homogeneous on a length scale of 3 mm.
- Homogeneity of the surface structure on a length scale of 3 mm is present in particular if the deviation of the level averaged over any circular section of the surface with a diameter of 3 mm from the level averaged over the entire surface is less than 10% of the maximum deviation of the level of the surface is from the average level of the surface.
- Such a micro structure is for the eyes of a normal-viewer practically imperceptible and leads to the impression of a homogeneous, unstructured surface even at an observation distance of approximately 50 cm.
- the known linen and leather grain structures of the surface of metal sheets are to be regarded as macro structures, which from a viewing distance of 50 cm are easily recognizable to the eye of a normal-viewer as a structure of the surface and should also be perceived as such.
- the structural elements of the surface structure have an average diameter of more than 1 mm.
- the structural elements of the microstructure have an average diameter of less than 0.5 mm, preferably less than 0.3 mm.
- the expansion of the structural elements in each direction aligned parallel to the surface of the metal sheet is less than 0.5 mm, preferably less than 0.3 mm.
- At least some of the structural elements of the microstructure are formed on the surface of the metal sheet as elevations with a maximum height of less than approximately 0.1 mm.
- at least some of the structural elements of the microstructure are formed on the surface of the metal sheet as depressions with a maximum depth of less than approximately 0.1 mm.
- the method according to the invention is particularly simple if the microstructure is applied to the surface of the metal sheet by embossing, in particular by means of an embossing roller.
- the disorder of the microstructure can be generated by an irregular sequence of differently shaped structural elements, by an irregular distribution of the structural elements over the surface, by an irregular alignment of the structural elements with respect to a predetermined longitudinal direction and / or by an irregular shape of the structural elements.
- the disordered structure of the microstructure produced according to the invention reduces the sensitivity to scratching and the visibility of fingerprints on the microstructured surface of the metal sheet, while the wear resistance under abrasive use and the ease of cleaning are improved.
- the microstructure has a periodicity length in at least one longitudinal direction of the metal sheet which is greater than ten times, preferably greater than 100 times, the average diameter of the structural elements of the microstructure.
- the disorder of the microstructure can be produced, for example, in that the microstructure comprises at least two types of structural elements which differ from one another in terms of their outlines, and in that these different types of structural elements are distributed on the surface of the metal sheet in an irregular sequence.
- Each of the structural elements can have a regularly shaped, that is to say a point and / or mirror symmetry, outline.
- the disorder of the microstructure can be increased in an advantageous manner if the microstructure comprises structural elements with irregularly shaped contour lines.
- the disorder of the microstructure is preferably produced in that the structural elements of the microstructure are distributed irregularly over the surface of the metal sheet.
- the distances between the outline centers of mutually adjacent structural elements do not have fixed, discrete values, but rather a scatter.
- angles which enclose the connecting lines that connect the outline centers of mutually adjacent structural elements with a predetermined longitudinal direction of the metal sheet do not have fixed, discrete values, but rather a scatter.
- the center of outline is to be understood as the center of gravity of the area bounded by the respective outline of the structural element in question.
- angles which enclose the connecting lines which connect the outline centers of mutually adjacent structural elements with one another with a predetermined longitudinal direction of the metal sheet are distributed substantially uniformly over the angular range from 0 ° to 360 ° .
- the disorder of the microstructure according to the invention can be further increased by the fact that at least some of the structural elements are not rotationally symmetrical and that the orientation of these structural elements relative to a predetermined longitudinal direction of the metal sheet does not have fixed, discrete values, but a scatter.
- orientation of the non-rotationally symmetrical structural elements with respect to the predetermined longitudinal direction of the metal sheet is distributed substantially uniformly over the angular range from 0 ° to 360 °.
- the centers of outline of the structural elements form a pattern which has a periodicity length in at least one longitudinal direction of the metal sheet which is greater than ten times, preferably greater than hundred times, of the average diameter of the structural elements of the microstructure. It is particularly favorable if the microstructure is essentially isotropic, that is to say it has no preferred direction.
- Such an isotropy of the microstructure leads in particular to the fact that a large part of the light incident on the surface of the metal sheet provided with the microstructure is not reflected directly, but diffusely. This high proportion of diffuse reflection reinforces the impression of homogeneity when viewing the microstructured surface of the metal sheet.
- the method according to the invention is particularly well suited for the production of stainless steel sheets, in particular chrome-nickel steel sheets.
- the present invention is based on the further object of creating a metal sheet which has low sensitivity to scratching and low visibility of fingerprints.
- the dependent claims 18 to 32 relate to special configurations of the metal sheet according to the invention, the advantages of which have already been explained above in connection with the special configurations of the method according to the invention.
- Claims 33 to 35 relate to a formed part which has been formed from a metal sheet according to the invention by one or more forming processes, for example by stamping and / or deep drawing.
- Claim 36 relates to a device for applying a surface structure to a surface of a metal sheet, which comprises an embossing element, in particular an embossing roller, the surface of which is provided with a surface structure which comprises, as structural elements, depressions and / or elevations, the surface structure as an unordered microstructure is trained.
- This microstructure of the stamping element can be etched and / or engraved in the surface of the stamping element.
- the surface of the embossing element is provided with a wear protection layer, for example made of chrome, TiN and / or TiC, in order to increase the durability of the embossing element.

- Metal sheet formed by deep-drawn sink formed by deep-drawn sink.
- Steel sheets in particular chrome-nickel steel sheets, are produced by first producing a hot strip from the melted steel alloy in a continuous caster, which is annealed in one or more annealing lines and descaled in a pickling line. A cold rolling process follows the hot strip annealing and pickling.
- the cold strip produced in this way is treated further either in openly heated, continuous annealing and pickling lines or in bright annealing plants.
- the steel strips are re-rolled on a skin pass mill, for example on a so-called Sendzimier stand, in order to improve the flatness, the surface fine structure and the gloss of the steel strip produced.
- a section 102 shown in FIG. 1 of a device for producing a steel sheet, designated 100 as a whole, comprises a skin pass mill 104 with two skin pass rollers 106 which rotate in opposite directions to one another.
- the steel sheet 108 to be treated runs through the vertical gap between the two skin-pass rollers 106 and is drawn off from a dispensing roller 110, deflected by means of a deflection roller 112 and is fed along the direction of travel 114 to the skin-pass rollers 106 of the skin pass mill 104.
- an embossing device 116 In the direction of passage 114 following the skin pass mill 104, an embossing device 116 is provided, which comprises an embossing roller 118, the peripheral surface of which is provided with a surface structure, and a counter roller 118, the peripheral surface of which is essentially smooth.
- the outer surface of the embossing roller 118 is provided with a surface structure which is designed as an unordered microstructure.
- the structural elements 128 are depressions, these depressions extend, starting from the smooth surface 130 lying between the structural elements 128, into the plane of the drawing in FIGS. 4 to 7; on the other hand, if the structural elements 128 are elevations, these elevations extend from the essentially smooth surface 130 out of the plane of the drawing in FIGS. 4 to 7.
- the microstructure shown in FIG. 4 comprises structural elements 128, the outline centers 132 of which are arranged in a regular manner, namely on the lattice points of a regular lattice, for example a square lattice with the periodicity length p.
- the center of outline is to be understood as the center of gravity of the area bounded by the respective outline 126.
- the microstructure shown in FIG. 4 is an unordered microstructure, since the microstructure comprises several, for example six different, types 126a to 126f of structural elements which differ with regard to their outline 126.
- the assignment of the different types of structural elements 128 to the lattice points of the lattice on which the arrangement of the outline centers 132 is based is random, so that the microstructure is disordered due to this random distribution of the different types of structural elements 128 despite the regular arrangement of the outline centers 132.
- the periodicity length of the microstructure along the circumferential direction 134 of the embossing roller 118 is preferably more than ten times the average distance between two adjacent structural elements 128 and preferably more than ten times the average diameter of the structural elements 128.
- the periodicity length of the microstructure of the embossing roller 118 matches the circumferential length of the embossing roller 118.
- the individual structural elements 128 of the microstructure can have any desired geometric shapes and can be designed, for example, as a cone, truncated cone, pyramid, truncated pyramid, spherical cap, knife-section contour, prism or the like.
- the average diameter of the structural elements 128 is preferably less than approximately 0.3 mm.
- the maximum height of the structural elements 128 (in the case of elevations) or the maximum depth of the structural elements 128 (in the case of depressions) on the embossing roller 118 is preferably less than approximately 0.5 mm.
- the structural elements 128 belonging to the same type are each oriented in the same way relative to the circumferential direction 134 of the embossing roller 118; however, it could also be provided that the orientation of those structural elements 128 which are not rotationally symmetrical varies with respect to the circumferential direction 134.
- the angular distribution of the orientation of the structural elements 128 with respect to the circumferential direction 134 can be an essentially uniform distribution over the angular range from 0 ° to 360 °.
- An alternative microstructure shown in FIG. 5 includes structural elements 128, all of which have the same outline 126.
- the microstructure shown in FIG. 5 is disordered because the outline centers 132 of the structural elements 128 are irregularly distributed over the circumferential surface of the embossing roller 118 and because the outline lines 126 of the structural elements 128 are oriented at irregularly varying angles relative to the circumferential direction 134 of the embossing roller 118.
- the angular distribution of the orientations of the outline lines 126 of the structural elements 128 relative to the circumferential direction 134 can be a uniform distribution.
- the microstructure shown in FIG. 5 is an isotropic microstructure.
- both the distances between the outline centers 132 of mutually adjacent structural elements 128 and the angular positions at which the outline centers 132 of mutually adjacent structural elements 128 are arranged are scattered.
- the alternative microstructure shown in FIG. 6 combines the disordering features of the microstructures shown in FIGS. 4 and 5.
- the microstructure shown in FIG. 6 namely comprises several, for example six, different types of structural elements 128 which differ with regard to their contour lines 126.
- the outline centers 132 of the structural elements 128 are also irregularly distributed over the surface of the embossing roller 118, so that the distances between the outline centers 132 of adjacent structural elements 128 and the relative angular positions of adjacent structural elements 128 are scattered.
- non-rotationally symmetrical structural elements 128 have a variable orientation relative to the circumferential direction 134 of the embossing roller 118.
- the angular distribution of the orientation of the structural elements 128 relative to the circumferential direction 134 can be a uniform distribution over the angular range from 0 ° to 360 °.
- the microstructure shown in FIG. 6 is also isotropic.
- the alternative microstructure shown in FIG. 7, like the microstructures shown in FIGS. 5 and 6, has an irregular distribution of the outline centers 132 of the structural elements 128 over the circumferential surface of the embossing roller 118.
- the microstructure shown in FIG. 7, however, is characterized in that the outline lines 126 of the structural elements 128 are not formed regularly are, that is, have neither point nor mirror symmetry. Rather, the outline lines 126 of these structural elements 128 are irregularly shaped.
- These irregularly shaped outline lines 126 are also randomly oriented relative to the circumferential direction 134 of the embossing roller 118, so that the microstructure shown in FIG. 7 is also isotropic.
- the microstructure pattern desired in each case is applied to the circumferential surface of the embossing roller 118, which consists, for example, of a steel material, by means of an etching process or an engraving process.
- samples, sketches, drawings or data sets, from which the desired microstructure can be seen are delivered to an engraving unit.
- the surface of the embossing roller is designed in such a way that the repeat is guaranteed, that is to say that no break in the surface structure of the embossing roller is visible at the point at which the two opposite edges of the predetermined microstructure adjoin one another.
- a photosensitive layer is applied to the surface of the embossing roller 118 and exposed according to the predetermined microstructure, preferably with the aid of a laser.
- the circumferential surface of the embossing roller 118 is then exposed to an acid, which removes the roller surface at the unexposed areas, which results in the desired microstructure on the circumferential surface of the embossing roller 118.
- the desired microstructure is to be applied to the circumferential surface of the embossing roller 118 by means of an engraving process
- the desired surface image is produced on the circumferential surface of the embossing roller 118 with the aid of an engraving technique, for example using a micro-grinding tool, a milling cutter or a chisel, the repeat also being used the embossing roller 118 is observed.
- the embossing roller 118 can be provided with a wear protection layer before and / or after the etching process or the engraving process with which the desired microstructure of the embossing roller 118 is produced.
- the peripheral surface of the embossing roller 118 is hard chrome-plated.
- a wear protection layer for example made of TiN or TiC, to the circumferential surface of the embossing roller 118 by means of a PVD method (Physical Vapor Deposition).
- the diameter of the embossing roller 118 is preferably more than approximately 100 mm, in particular more than approximately 200 mm, since with such a comparatively large diameter, which exceeds the diameter of conventional skin pass rollers, a more precise three-dimensional structuring of the structural elements 128 of the microstructure on the peripheral surface of the embossing roller 118 is achievable.
- a microstructure which is complementary to the microstructure on the peripheral surface of the embossing roller 118 is rolled into the upper side 136 of the steel sheet 108 facing the embossing roller 118. Since the circumferential surface of the embossing roller 118 is closed in a ring, the microstructure applied to the top 136 of the steel sheet 108 has a periodicity length which corresponds to the circumferential length of the embossing roller 118.
- the microstructure generated on the upper side 136 of the steel sheet 108 corresponds to the microstructure of the circumferential surface of the embossing roller 118 described above with reference to FIGS. 4 to 7, the structural elements 128 ′ designed as depressions on the embossing roller 118 being designed as elevations correspond to the top of the steel sheet 108.
- structural elements 128 designed as elevations on the embossing roller 118 correspond to structural elements 128 ′ designed as depressions on the upper side 136 of the steel sheet 108.
- Another difference between the microstructures on the embossing roller 118 on the one hand and on the structured steel sheet 108 on the other hand is that the height of the elevations produced on the top 136 of the steel sheet 108 is less than the depth of the corresponding depressions on the embossing roller 118, and that the depth of the depressions produced on the steel sheet 108 is less than the height of the corresponding elevations on the embossing roller 118.
- the amplitude of the microstructure produced on the upper side 136 of the steel sheet 108 is determined by the contact pressure with which the embossing roller 118 and the counter roller 120 are pressed against one another and / or by the Width of the gap between the circumferential surface of the embossing roller 118 on the one hand and the counter roller 120 on the other hand is determined.
- the amplitude of the microstructure produced on the steel sheet 108 can thus be set to a desired value by embossing depth adjustment on the embossing device 116.
- the height of the elevations produced on the steel sheet 108 or the depth of the depressions produced on the steel sheet 108 is preferably less than approximately 0.05 mm.
- the underside 138 of the steel sheet 108 remains essentially smooth even after passing through the embossing device 116.
- the total thickness of the steel sheet 108 is reduced by less than 10% as it passes through the stamping device 116.
- the steel sheet 108 can be subjected to a further annealing process, a so-called recovery annealing, in order to eliminate the strain hardening which was caused by the embossing process and to almost restore the deformation properties of the steel sheet 108 which existed before the embossing process ,
- the steel sheet 108 produced in the manner described above has a microstructured upper side 136 which has a normal vision The observer appears homogeneous at a viewing distance of at least 50 cm.
- the top 136 of the steel sheet 108 Due to the embossed microstructure, the top 136 of the steel sheet 108 has a reduced sensitivity to scratching, a reduced visibility of fingerprints, an increased wear resistance under abrasive use and an increased ease of cleaning.
- formed parts can be formed in a manner known per se by one or more forming processes, for example by embossing and / or deep drawing, which either represent a finished end product or a part of a finished end product which other formed parts or other materials is assembled to the finished end product.
- Such an end product which consists of one or more formed parts from the steel sheet according to the invention, can be, for example, a sink 140 shown in FIG. 8, which comprises a sink 142, a waste bowl 144, a drainer 146 and a battery bank 148.
- the sink 140 can be produced from a single sheet metal blank of the steel sheet 108 produced according to the invention by reshaping, the steel sheet 108 being oriented such that the one provided with the microstructure Upper side 136 forms the visible side of sink 140 facing the user of sink 140.
- a sink can also be composed of a plurality of such shaped parts which are welded together.
- the steel sheet 108 provided with the microstructure it is also possible, for example, to produce table tops, worktops or sink accessories, for example drip trays, or outer shells of mixer taps or furniture or furniture parts made entirely or partially of sheet steel.
