Definitions
- the present invention relates to a metallic product having an improved gloss after painting, as well as to methods for its manufacture. It relates in particular to cold-rolled metal sheets, which will be more specifically referred to in the description which follows, but it can also be applied to other types of metal products intended to be painted.
- the object of the present invention is to provide a surface morphology of a metal product ensuring that it has an optimum shine after painting while being compatible with the requirements of the other processing operations, in particular by forming.
- the metal product having an improved gloss after painting which is the subject of the present invention, is essentially characterized in that its surface consists of a plurality of flat and smooth facets, preferably located in the same plane and in this that these facets represent at least 30%, preferably at least 50% of the total surface of the product.
- said facets are separated by valleys ensuring the roughness of the surface of the metal product.
- these valleys form a network drawing a regular pattern, possibly repetitive in the surface of the product.
- the dimension of each of said facets, in any direction in its plane is advantageously between 50 ⁇ m and 200 ⁇ m.
- the facets are of the same order of magnitude as the valleys that separate them; they then constitute only an insufficient portion of the surface and do not provide the desired gloss.
- a dimension greater than 200 ⁇ m is not desirable, in order to avoid the appearance of harmful specific phenomena, such as micro-seizure during the forming operations.
- This characteristic can also be expressed by specifying that the pitch of said network is advantageously between 50 ⁇ m and 200 ⁇ m.
- the present invention also relates to methods for obtaining the surface morphology of a metal product which has just been described.
- the metal product is given a surface that is as flat and smooth as possible during the first stages of its manufacture and the aforementioned network is formed in this surface during the last stage of manufacture.
- the surface of the product may be provided, before the last manufacturing step, with a very fine roughness which deviates little from the ideal plane and in any case less than the final roughness corresponding to the above-mentioned network, if this is the case. necessary to allow the first stages of manufacturing.
- the final roughness is imparted by a tool, the surface of which is itself provided with a network of ridges intended to print the above-mentioned network of valleys in the surface of the product.
- the essentially flat portions of the surface of the tool lying between the ridges do not come into contact with the flat and smooth surface of the product. However, even if such contact did occur, the flat portions of the surface of the tool would not destroy the flatness of the facets of the surface of the product lying between the valleys of the network thus printed.
- the surface is provided with a substantially regular roughness, before the last stage of its manufacture; then, during a subsequent step which may be the last, the vertices, that is to say the peaks or crests of this roughness, are crushed, using a smooth tool so as to form plane facets and smooth separated by the valleys of said roughness.
- a fragment of a steel sheet 1 intended to be painted. It may in particular be a sheet metal bodywork.
- the surface of the sheet should be perfectly flat and smooth as indicated by the trace of the ideal plane 2.
- the real surface comprises flat and smooth facets 3 forming part of ideal plane 2, separated by valleys 4 which make it possible to ensure the lubrication of the sheet during the forming operations.
- the dimension d of the facets is between 50 ⁇ m and 200 ⁇ m.
- Fig.2 illustrates, in three stages a, b, c, the manufacture of a cold-rolled sheet according to the invention by the first embodiment described above.
- a sheet 1 flat and smooth, obtained by appropriate prior operations and intended to receive its final morphology.
- a finishing rolling cylinder 5 for example a work hardening cylinder, is provided with ridges 6 forming on its surface a network (not shown).
- the cylinder 5 is applied to the sheet 1 and there prints a network of valleys 4, the portions of the flat surface of the sheet included between the valleys may or may not meet the portions of the surface of the cylinder included between the ridges 6.
- view c shows the sheet 1 provided, on one face in the present example, with flat and smooth facets 3 separated by a network of valleys 4.
- FIG.3 illustrates in three steps e, f, g, the manufacture of a sheet according to the invention by the second embodiment mentioned above.
- View e shows in section, a sheet 1 provided with a regular roughness, for example with a tandem rolling mill.
- This sheet is in view f, crushed on the skin-pass by a cylinder 5, the smooth surface of which smoothes the peaks of the initial roughness.
- the sheet 1 has each time been shown with a single face treated in accordance with the invention. It goes without saying that this invention also covers cases where all the faces of the product have, over at least part of their extent, the particular morphology which is proposed here.
- a treatment of the surface of rolling mill rolls by means of an intermittent laser beam makes it possible to create in this surface microcraters serving to imprint in the surface of a sheet the network of valleys leading to the desired morphology.
