Definitions

  • the invention relates to the field of metallic aluminum alloy bottles as well as aerosol cans, still known to those skilled in the art under the names of “bottle-can” or “bottle beverage can” and aerosol can, respectively. , manufactured by stamping-stretching, that is to say according to a process including these two basic steps, associated in particular with the complementary steps of necking (or “necking"), possible threading (or “threading”) and hemming (or “curling”) ").
  • the invention relates more particularly to aluminum alloy sheets of composition and heat treatment which are particularly suitable for this type of application and which in particular have good formability during the abovementioned stages, in particular for shrinking, as well as a low anisotropy necessary in particular during the drawing and drawing stages.
  • Aluminum alloys are increasingly used in the manufacture of beverage cans, also known under the name of "cans” or “beverage cans”, but also of metallic bottles or “bottle-cans” and aerosol, because of their very good aesthetic appearance, especially in relation to plastics and steels, their ability to be recycled and their good resistance to corrosion. All aluminum alloys referred to below are designated, unless otherwise stated, according to the designations defined by the “Aluminum Association” in the “Registration Record Series” which it publishes regularly.
  • Beverage boxes, or cans, also known to those skilled in the art under the name of "cans” or “beverage cans”, are produced by stamping-drawing from alloy sheets of the 3104 type in metallurgical state. H19.
  • This metallurgical state corresponds to a continuous vertical plate casting, followed by scalping, homogenization, hot rolling followed by cold rolling in several passes with an overall cold reduction rate of 80 to 90%, without intermediate annealing.
  • the sheet undergoes a first cutting and stamping operation; during this stage, the sheet metal coil feeds a press, also called a "cupper", which cuts discs called blanks and performs a first stamping operation to produce cups also known as "cups”.
  • the cups are then routed to a second press or "bodymaker” where they undergo at least a second stamping, also called re-stamping or recovery stamping, and several successive draws; these consist in passing the stamped blank through drawing rings in order to lengthen the metal and to thin it.
  • the bottom on the other hand, is shaped like an inverted dome so that it can withstand the internal pressure produced by the container. Boxes are thus gradually obtained, the walls of which are thinner than the bottom. These boxes are then treated in a machine which gives them a rotary movement while a shear cuts them to the desired height. These are then washed in several cleaning and rinsing baths and then typically dried between 180 and 250 ° C for 5 to 10 minutes. They are then printed by rollers and then varnished on the outside before baking typically between 200 and 230 ° C for 5 to 10 minutes. A coating is then sprayed inside the preform before a new cooking, typically between 190 and 220 ° C for 3 to 10 minutes. The box obtained at this stage is called "preform".
  • the beverage cans are then routed to a shrinking and planking station (or edging) also known as a "necker flanger" where the upper part of the preform undergoes several successive narrowing in diameter and a edging intended for the subsequent laying of the lid.
  • a shrinking and planking station also known as a "necker flanger”
  • Metal bottles and aerosol cans or aerosol cans, made of aluminum alloy, are traditionally manufactured by impact spinning, from pins produced by casting on a wheel.
  • the shape of the developed perimeter is not favorable. It is in fact a profile with six horns, two of which positioned respectively at 0 and 180 ° from the rolling direction and four at 45 ° on either side of said direction, in accordance with the figure 1 . It turns out that such a configuration, due to the horns at 0 and 180 °, presents a serious risk of giving rise to the phenomenon known as “pinched horns” well known to those skilled in the art, with the risk of breakage during subsequent stretching. What is more, the material does not soften very much, that is to say that its mechanical resistance decreases little during the firing of varnishes, which makes shaping for shrinking or "necking" more delicate.
  • the document FR2432555 A1 describes an aluminum alloy with magnesium and manganese as main alloying constituents for the production of a strip suitable for the production of bodies and can lids by stamping and re-stretching, and its production method.
  • the alloy described contains: 1.3 to 2.5% magnesium; 0.4 to 1.0% manganese; 0.1 to 0.9% iron; 0.1 to 1.0% silicon; 0.05 to 0.4% copper; 0 to 0.2% titanium; the rest essentially of aluminum.
  • the total magnesium and manganese content is 2.0 to 3.3% and the magnesium / manganese ratio is 1.4: 1 to 4.4: 1.
  • the invention aims to solve these difficulties by allowing deep drawing of the cups with drawing ratios up to 1.9 or more, stretching without breakage, and above all shaping by shrinking or "necking" with a reduction in diameter. of the “preform” of the order of 50%, without cracks or folds, as during “threading” in the case of bottles and hemming in this same case as well as in that of aerosol cans.
  • the invention also relates to a sheet produced by a process as mentioned above and whose elastic limit after a heat treatment of 10 min. at 205 ° C, simulating the firing of varnishes, is from 170 to 210 MPa and the breaking load from 200 to 240 MPa.
  • the reduction in the elastic limit of said sheet before and after heat treatment simulating the firing of varnishes is from 20 to 40 MPa.
  • the anisotropy index of said sheet measured after its cold rolling to a thickness of 0.35 to 1.0 mm, by the method of buckets according to standard NF EN 1669 is from 0.5 to 4.0 %.
  • said sheet has, at the end of the test according to the bucket method, horns at 45 ° on either side of the rolling direction and no horn at 0 and 180 ° from said direction.
  • the formability of said sheet is such that it does not reveal any cracks or folds during deep drawing in two passes, the first with a drawing ratio, ratio between diameter of the blank and diameter of the punch, between 1.5 and 1.9, the second with a stamping ratio between 1.3 and 1.6.
  • said sheet has, after cold rolling up to a thickness of 0.35 to 1.0 mm, an elongated grain microstructure with a slenderness factor, ratio of grain size in the direction of rolling related to the grain size in the thickness direction, measured after anodic oxidation and in optical microscopy in polarized light, between 2 and 10.
  • the subject of the invention is also a metal bottle, also known to a person skilled in the art under the name of "bottle can” or “bottle type beverage can”, made from such a sheet having one or more of the characteristics mentioned above, including a so-called metallic bottle, that is to say one whose main walls are not strictly cylindrical.
  • aerosol can also known to those skilled in the art under the name of "aerosol can” or even “aerosol dispenser”, made from said sheet having one or more of the characteristics aforementioned, including a so-called aerosol can, that is to say one whose main walls are not strictly cylindrical.
  • the figure 1 represents the "horn profile", that is to say the shape of the perimeter developed from the top of the "cups" at the end of the first stamping, with, on the ordinate, the ratio of the height of the horn to the average height of the cup and, on the abscissa, the angle ⁇ with respect to the rolling direction.
  • the figure 2 represents the Vickers Hv microhardness measured under a load of 100 g on preforms before shrinking (therefore having undergone the firing of varnishes) as a function of the elastic limit R0.2 in MPa measured on the sheets before transformation but after simulation treatment 10 min. at 205 ° C.
  • the black diamonds correspond to the material according to the invention, and the white squares to materials not in accordance with the invention. It reveals a linear correlation between these two values.
  • the figure 3 represents the scrap rate in%, according to three zones (A from 0 to 10%, B from 10 to 30% and C beyond) during the shrinking or "necking" operation depending on the Vickers Hv microhardness ci above, for materials in accordance with the invention (black diamonds) and non-conforming (white squares).
  • the invention consists in a judicious choice of alloy and heat treatment, as well as of transformation range, of the sheet or strip used for the manufacture of metal bottles, or "bottle-cans", or aerosol cans.
  • the chemical composition of the alloy expressed in weight percentages (% by weight) is as follows: Si: 0.20 - 0.35, Fe: 0.30 - 0.55, Cu: 0.05 - 0.20, Mn: 0.70-0.90, Mg: 0.80 - 1.25, Zn: ⁇ 0.25, Ti: ⁇ 0.10, other elements ⁇ 0.05 each, and ⁇ 0.15 at total, aluminum remains.
  • a minimum of 0.10%, and preferably 0.20% makes it possible to obtain a sufficient rate of Al 12 (Fe, Mn) 3 Si phase at the end of the homogenization treatment after casting of the plates.
  • This type of abrasive phase has the particularity of avoiding fouling of the drawing rings by agglomerates of alloy particles and oxide and therefore of ensuring a good surface quality of the blanks by avoiding that the he skilled in the art knows as "gripping".
  • Fe is also, in general, an impurity, the content of which increases during recycling. This must be less than 0.55% and preferably 0.50% to avoid the formation of coarse primary phases during casting, phases detrimental to formability.
  • a Si content of at least 0.10% and better of 0.20%, as well as of Fe of 0.30% and better 0.35%, is necessary for a good control of the anisotropy of the final product, that is to say say sheet or strip, and therefore subsequent shaping operations.
  • the Si content is at least 0.20%.
  • the elements Cu, Mn and Mg are essentially hardening elements, the contents of which allow the mechanical characteristics of the sheet to be controlled at the various stages of manufacture, from the blank to the final product.
  • Hardening is mainly linked to the presence of these elements in solid solution in the primary aluminum matrix. Cu also allows hardening through fine precipitates.
  • Cu has a content limited to 0.20% to promote restoration during the heat treatment of varnish firing and thereby improve the formability necessary in particular for shrinking or "necking" as well as for threading and / or hemming.
  • Mn is limited to 1.0% and better 0.90% to avoid the formation of coarse primary phases during casting, detrimental to formability.
  • the Mn content is limited to 0.90%
  • Mg is limited to 1.3% and better 1.25% so as not to reduce formability too significantly, especially for stamping operations.
  • the Mg content is limited to 1.25%.
  • the minimum contents of Cu, Mn and Mg ensure the minimum mechanical characteristics required, in particular for the resistance to internal pressure of the bottom of the bottle or case.
  • Zn is limited to 0.25% mainly due to the legislation on products for food applications translated into standard NF EN 602.
  • Ti is a refining element of the casting structure but also forms primary phases unfavorable to formability. For the latter reason, its content is limited to less than 0.1%.
  • the manufacture of the sheets according to the invention mainly comprises the casting, typically continuous vertical (CCV), of the plates and their scalping.
  • CCV continuous vertical
  • the scalped plates then undergo conventional homogenization and then hot rolling followed by a first cold rolling with a reduction rate of 35 to 80%.
  • the reduction rate before intermediate annealing must be at least 35% to obtain complete recrystallization during said intermediate annealing. It must not exceed 80% so that the reduction carried out after said intermediate annealing is sufficient to obtain mechanical characteristics after annealing for 10 minutes at 205 ° C in the ranges announced below.
  • the intermediate product undergoes recrystallization annealing at a temperature between 300 and 400 ° C, better between 340 and 360 ° C, or at a target temperature of 350 ° C, for at least one hour.
