Definitions

the invention relates to a flat, rolled aluminum alloy alloy, the aluminum alloy having the following proportions by weight in percent by weight: 2 ⁇ Mg ⁇ 5 Mn ⁇ 0.5 Cr ⁇ 0.35 Si ⁇ 0.4 Fe ⁇ 0.4 Cu ⁇ 0.3 Zn ⁇ 0.3 Ti ⁇ 0.15 Others in total not more than 0.15, individually a maximum of 0.05, remainder Al, wherein the semifinished product has been rolled from a billet and has been subjected in the rolling process at least one intermediate soft annealing between two cold rolling passes and a final soft annealing respectively in a chamber furnace and a method for production of such a flat, rolled semi-finished product.
These flat, rolled semi-finished products are Aluminum strips or sheets for further processing by deforming or deep drawing, for example for Production of body panels for the Automotive industry. It is known that Standard alloys such as e.g. AA5052, AA5754 or AA5182, the alloy shares in the specified ranges when thermoforming prone to the formation of Flowing figures, in particular flow lines, are. such Flow figures are for sophisticated demands on the surface in body exterior parts highly undesirable that they are still visible after painting.
Standard alloys such as e.g. AA5052, AA5754 or AA5182
the present invention is based on the object, a flat, rolled semi-finished aluminum alloy or a method for producing such to provide flat, rolled semi-finished products, which the use of standard alloys without addition of Zn and Cu or other elements without elaborate production facilities and an improved Process reliability with regard to a flow line freedom the deep-drawn or deformed final product guaranteed.
the previously derived and indicated object is according to the first teaching of the invention solved by the Forming degree before the first intermediate soft annealing at least 50% and not more than 30% before the final soft annealing and the semi-finished product after the final soft annealing by 0.1 to 0.5% has been stretched.
the semifinished product according to the invention has a long duration Shelf life of several years, during which the properties do not change significantly.
the manufacturing process for producing the flat, rolled semi-finished product according to the invention a has great robustness.
An advantageous embodiment undergoes the Inventive, rolled semi-finished product according to the invention in that the semi-finished product after the final soft annealing by 0.2 to 0.5% has been stretched.
the stretching increased by at least 0.2% continue the process reliability in the production of the inventive semi-finished product.
the stretching of the flat, rolled semi-finished product can open done in different ways. It is conceivable for example, stretching in a strip stretching machine, however also the stretching with help by alternately diverting the Strip or sheet metal in a so-called leveling system, at which the band at each deflection on the outside Radius is stretched and compressed in the inner radius.
the above derived and indicated task by a procedure for the production of a flat, rolled semi-finished product solved an aluminum alloy, in which the semi-finished one having the above alloying parts Rolled bar is rolled in the rolling process at least one Intermediate soft annealing between two cold rolling passes and a final annealing in each case in a chamber furnace is subjected, wherein the degree of deformation before the first Intermediate soft annealing at least 50% and before Final soft annealing is at most 30% and the semi-finished product After final annealing, 0.1 to 0.5% is stretched.
the embodiment of the plant for producing a flat, rolled semi-finished product according to the invention an aluminum alloy, in particular a semi-finished product for the manufacture of body panels, has a Hot rolling line 1 with a reversing stand 2 and optional a subsequent multi-stage hot rolling stand 3 on.
This hot rolling line 1 is a bar 4, for example made of a standard alloy such as AA5052, AA5754 or AA5182 rolled off and then in a Aufhaspelstation to a coil 5 wound up.
the tape After cooling the coil 5, the tape is on a first cold rolling line 6 one or more Subjected to cold rolling passes, with the reduction of Recrystallization temperature of the band of the degree of deformation at least 50%.
the cold-rolled, re-coiled band in one Chamber furnace 7 soft annealed.
the Soft soft annealing recrystallizes the relatively coarse one Structure of the tape almost completely, so that the tape in soft and recrystallized state after Intermediate annealing is present.
the soft-annealed band on a second Cold rolling mill 8 again cold rolling with a Subjected to degree of deformation of at most 30%. Through this Measure will only a small number of defects in the Band generated, so that the band after the last cold rolling has a fine-grained structure.
leveling system 10 can also be a Band stretching machine can be used on which the band over his entire cross section is stretched.
