Definitions
- the invention relates to a method for manufacturing very thin strips of thickness. less than or equal to 12 ⁇ m, aluminum-iron alloy.
- Such bands are used in particular for the manufacture of multilayer complexes comprising a layer of paper or cardboard, a layer of aluminum alloy and a layer of polymer, usable for making aseptic food packaging, flexible or rigid brick type.
- the desired use properties for very thin alloy strips aluminum are good mechanical strength, sufficient elongation, very low number of holes per unit area and good tear resistance and folding.
- the absence of holes is mainly linked to the grain size, which must, in any assumption, be less than the final thickness.
- the alloy chosen can be cast and laminated easily, so that it is not too costly to develop, in particular that it does not require too low a silicon content, and that the product transformation range is not too complicated, especially that it avoids too many heat treatments.
- alloys usually used for this application are alloys of the type 1100 or 1200 containing less than 1% by weight for the sum of the contents silicon and iron. It is also known to use, to improve the resistance mechanical, higher iron alloys and addition of manganese, such as alloys 8006 and 8015, registered with the Aluminum Association respectively in 1978 and 1988.
- the registered composition of 8006 is (% by weight): If ⁇ 0.4 Fe: 1.2 - 2 Cu ⁇ 0.30 Mn: 0.3 - 1 Mg ⁇ 0.10 Zn ⁇ 0.10
- the registered composition of 8015 is: If ⁇ 0.30 Fe: 0.8 - 1.4 Cu ⁇ 0.10 Mn: 0.10 - 0.40 Mg ⁇ 0.10 Zn ⁇ 0.10
- a major drawback of high iron alloys is the difficulty of recycling the manufacturing scraps for other applications; indeed, the manufacture of tapes very thin is a delicate operation which leads to a significant centering in generating a lot of waste.
- One way to avoid this drawback is to use, for production of the blanks, a continuous casting machine, for example a casting between cylinders, which directly recycles scrap and scrap from manufacturing in the machine feed oven. This advantage is in addition to intrinsic advantages of continuous casting, especially the low cost investment.
- Patent EP 0750685 (Alcan International), filed in 1994, relates to a thin sheet of thickness between 5 and 40 ⁇ m, of composition (% by weight): If ⁇ 0.4 Fe: 1.2 - 2.0 Mn: 0.2 - 1.0 Mg and / or Cu: 0.1 - 0.5 Zn ⁇ 0.1 with an average grain size of less than 5 ⁇ m after final annealing.
- the metal can be cast by conventional semi-continuous casting, or by continuous casting between cylinders or between belts.
- Application WO 98/45492 (Alcan International) describes a recyclable thin sheet, intended in particular for household applications, of composition: Si: 0.2 - 0.5 Fe: 0.4 - 0.8 Cu: 0.1 - 0.3 Mn: 0.05 - 0.3 containing at least 2% by weight of dispersoids and at least 0.1% of copper and / or manganese in solid solution.
- the alloy is poured continuously and an intermediate annealing is carried out during cold rolling.
- the object of the invention is to provide a method for manufacturing strips of alloy of aluminum type - iron of thickness less than or equal to 12 ⁇ m, and preferably less than 9 ⁇ m, using continuous casting between cylinders, and leading to belts having both good mechanical strength and high strength tearing and folding, under technical and economic conditions compatible with significant industrial production.
- the method according to the invention combines a particular composition inside the AA composition of 8006 and a manufacturing range, leading to properties instructions for the production of packaging complexes food, avoiding penalizing constraints on the industrial level.
- the composition of the alloy has a silicon content of between 0.15 and 0.40%, which does not require the use of a pure base and therefore does not need to be particularly controlled, contrary to the teaching of US patent 5,380,379 which recommends a silicon content of less than 0.2% to avoid the formation AlFeSi and AlMnSi intermetallics.
- the iron content between 1.1 and 1.7%, and preferably ⁇ 1.4%, is in the low range of 8006, and is in that 8015.
- the manganese content between 0.3 and 0.5%, is also in the low range of 8006.
- the magnesium and copper contents are kept at low levels.
- the alloy is cast using a continuous strip casting machine between two cooled cylinders, such as the Jumbo 3C TM from Pechiney
- Rhenalu The casting takes place at a thickness between 2 and 10 mm, at a speed casting between 0.5 and 3 m / min. It is possible to recycle all of the production scraps and rejects in the machine feed oven.
- the band casting is then homogenized at a temperature between 450 and 620 ° C for a period of between 8 and 40 h, then cooled slowly.
- a cold roughing rolling is carried out to a thickness between 0.8 and 0.3 mm, then an intermediate annealing at a temperature between 200 and 400 .. C, so as to obtain a structure fine, and preferably between 302 ° C and 370 ° C to obtain a recrystallized structure, with a grain size not exceeding 30 ⁇ m, and preferably 15 ⁇ m.
- the strip is then cold rolled to the final thickness according to the usual technique, then subjected to a final degreasing annealing at a temperature between 200 and 300 ° C, for a period of at least 50 h., Depending in particular the width of the strip.
- the strips according to the invention have a breaking strength greater than 100 MPa, an elastic limit greater than 80 MPa, an elongation at break greater than 3% and a porosity according to standard EN 546-4 less than 10 holes per dm 2 . They also have improved resistance to tearing and folding compared to strips from conventional casting.
- US patent 5,380,379 recommends a first intermediate annealing between 200 and 250 ° C, at a thickness between 0.31 and 0.38 mm, then a second intermediate annealing between 200 and 300 ° C, at a thickness between 20 and 45 ⁇ m.
- the strips obtained by the process according to the invention are particularly suitable for the manufacture of multilayer complexes, for example paper complexes or cardboard - aluminum - polymer for making food packaging aseptic type bricks. They can also be used bare, lacquered or varnishes for various types of packaging.
- the alloy was cast in width 1500 mm, in thickness 8 mm and at a speed of 0.96 m / min on a casting machine between two cooled cylinders of Jumbo 3C brand TM from Pechiney Rhenalu.
- the casting strip was homogenized for 12 h at a temperature of 600 ° C.
- the strip was then cold rolled to the thickness of 0.5 mm, then subjected to an intermediate annealing on a 12 h coil at 350 ° C, so that the metal recrystallizes with fine grains. She was then relooked up to the final thickness of 6.60 ⁇ m, then subjected to a final degreasing annealing for approximately 80 h at 280 ° C.
- the porosity of the strip was also measured by the number of holes per dm 2 according to standard EN 546-4. This porosity is 6 holes per dm 2 , compared to an average value of 13 holes per dm 2 for the 1200 alloy in conventional casting.
- Tear resistance tests were carried out for sheets cut from strips of 1200 alloy from conventional casting and of thickness 6.3, 6.6 and 9 ⁇ m, and from strips according to the invention of the same thickness. .
- the tests were carried out by the Elmendorf method according to standard EN 21974 (ISO 1974).
- the test consists of determining the force necessary to propagate a tear on a test piece.
- a first test without a predefined slot gives an indicator of the resistance to initiation and propagation of a crack; and a second with predefined slit makes it possible to quantify the resistance to propagation alone.
- the force chosen from the list in paragraph 1 of appendix A of the standard is 4 N for the initiated tear, and 32 N for the unstarted tear.
- Each test piece consists of a sandwich of 8 sheets, the rolling direction of which coincides with the direction of crack propagation.
- the results (average of several tests) relating to the average force necessary for tearing F1 (with crack initiation) and F2 (without crack initiation) are collated in Table 2.
- the sheets according to the invention have resistance to higher tear than those produced by conventional casting.
- Bending resistance measurements were carried out according to ISO 5626, in using Lhomargy's device.
- the folding stress is produced by a back and forth movement of a slot located between 4 cylinders which control the angle folding.
- the belt fastening device and the tension force were slightly modified to take into account the difference between aluminum and paper.
- the distance between the jaws has been lengthened to 35 mm (instead of 28.5 mm) and the counterweight adjusted to give tensions of 0.4 N, 1.7 N and 3 N (instead of 9.81 N and 8 N).
- the samples used have the dimensions 170 mm x 15 mm (instead of 100 x 15 mm), the rolling direction being aligned with the folding blade, i.e. perpendicular to the direction of the tension force.
- the tests were carried out on 1200 alloy strips of thickness 6.6 and 9 ⁇ m, from conventional casting, and strips according to the invention of the same thickness.
- the strips according to the invention although more resistant mechanically have rather better bending resistance than the alloy 1200 in conventional casting for the thickness 6.6 ⁇ m, and roughly equivalent for the thickness 9 ⁇ m.
