Definitions

  • the present disclosure relates to the technical field of metallic materials and their processing, in particular to an aluminum alloy sheet for a can body with excellent perforation resistance and low cost, and a method for preparing the same.
  • aluminum cans Compared with tin-plated steel cans, aluminum cans have become one of the most heavily used materials in the metal packaging industry due to their advantages like light weight, corrosion resistance, good thermal conductivity, good formability, easy recycling, simple post-printing processing, and environmental friendliness.
  • An aluminum alloy sheet for a can body may be manufactured by homogenizing, hot rolling and cold rolling a large-size flat cast slab of aluminum alloy. After the resulting sheet is degreased, washed and oiled, it may be used to manufacture beer and beverage cans through processes such as cup body forming, washing, drying, coating, baking, necking and flanging.
  • Beer and beverage cans need to have a certain compressive strength. However, after baking, the strength of the cans will decrease. In order to reduce the degradation of the strength after baking, it is necessary to control and optimize the solid-dissolution amounts, relative contents and precipitation amounts of alloying elements including impurity elements. In the case of improper control, substrates with higher perforation risk will flow into downstream can-making enterprises. Since post-canning tracing is difficult for the downstream enterprises, to be on the safe side, they often isolate or return the entire batch of substrates with perforation defects. The sum of claim for compensation not only involves the can bodies themselves, but also involves the value of the entire cans and the user experience, which often exceeds the cost of the can bodies by many times, causing huge losses and waste of resources. Therefore, if recycled aluminum can be put into use, it will bring huge long-term benefits to the ecological environment and energy utilization.
  • the inventors have conducted service simulation tests on the composition and impurity distribution of an aluminum material, and have discovered that the type and spatial size distribution feature of an intermetallic compound in the matrix are closely related with the incidence of perforation defects in the can material.
  • one of the objects of the present disclosure is to provide an aluminum alloy sheet for a can body, wherein the aluminum alloy sheet for a can body is prepared using a recycled can body material of the same series, wherein the aluminum alloy sheet for a can body comprises, by mass percentage, Mn: 0.70-1.35%, Mg: 0.80-1.55%, Si: 0.30-0.50%, Fe: 0.40-0.80% (e.g., 0.40-0.75%), Cu: 0.15-0.35%, Zn: 0-0.30%, Ti: 0-0.08%, a rare earth mixture of Ce+La: 0.005-0.008%, and a balance of Al and other unavoidable impurities, wherein a mass ratio of Fe/Si is greater than 1.5; and the recycled can body material of the same series is added in an amount that accounts for at least 50% of a total weight of the aluminum alloy sheet.
  • the present disclosure provides an aluminum alloy sheet for a can body whose chemical composition is designed to limit the mass ratio of Fe/Si to greater than 1.5, and have a relatively increased content of Mg, so as to overcome the negative influences of Si and Fe on the microstructure and product performances.
  • the amount of the recycled can body material of the same series added accounts for at least 50% of the total metal mass, the input of fresh aluminum is reduced greatly, which is conducive to low-carbon production of a cost-effective aluminum alloy material for a can body.
  • the excess Si combines with Mn to form a complex ternary phase Al 12 Mn 3 Si 2 , with Mg to form a Mg 2 Si precipitation phase, and with Fe to form an AI(FeMn)Si quaternary phase.
  • the corrosion potential follows the following relationship: Mg 2 Si>Al 6 Mn> ⁇ AlFeMnSi> ⁇ -Al. Therefore, increasing the relative proportion of ⁇ AlFeMnSi is beneficial to improving the corrosion resistance of the can material.
  • the proportion of the ⁇ AlFeMnSi phase also has a non-negligible positive influence on the control of the cubic texture in the subsequent rolling process.
  • the porosity of the aluminum alloy sheet for a can body does not exceed 0.15%.
  • the thickness of the aluminum alloy sheet for a can body is 0.23-0.50 mm.
  • the aluminum alloy sheet for a can body has a tensile strength of ⁇ 290MPa, for example, 290-310MPa; a yield strength of ⁇ 270MPa, for example, 270-290MPa, and an elongation of ⁇ 6.0%, for example, 6.0-7.0%.
  • the perforation incidence of the aluminum alloy sheet for a can body is ⁇ 10ppm, for example, ⁇ 5ppm.
  • the perforation fracture surface of the aluminum alloy sheet for a can body is devoid of impurities.
  • the primary alloy composition of the aluminum alloy sheet for a can body provided by the present disclosure is limited, and the conversion ratio of the ⁇ AlFeMnSi phase is quantitatively controlled, so that the distribution of the second phase is more dispersive and more uniform, and the size distribution at a hazardous level is further narrowed.
  • the incidence of perforation defects after canning is reduced by at least 10ppm in comparison with those products manufactured by conventional processes, indicating excellent perforation resistance.
  • Another object of the present disclosure is to provide a method for preparing an aluminum alloy sheet for a can body, comprising the following steps:
  • This technical solution allows the matrix structure, impurity elements and inclusions of the aluminum alloy sheet made using a recycled can body material to be more evenly distributed, reducing the incidence of perforation defects in the thin aluminum alloy sheet. At the same time, this solution also reduces the input of fresh aluminum, which is conducive to low-carbon production of a cost-effective aluminum alloy material for a can body.
  • an aluminum ingot with Al ⁇ 99.70% by mass percentage is selected.
  • the recycled can body material is a Series 3 recycled aluminum alloy material.
  • a recycled material is also named a recovered material, or a secondary material. It is an aluminum alloy or aluminum metal obtained by smelting an aluminum waste material, an aluminum alloy waste material, or an aluminum-containing waste material. A recycled material must undergo strict internal control testing before it is put into use.
  • the Series 3 recycled aluminum alloy material used in the present disclosure has a well-known meaning in the art, and refers to an aluminum alloy with AlMn as the main component, originating from waste materials from the AlMn aluminum alloy process, recycled can materials, etc.
  • the metal additives are added in the order of Mn, Si, Fe, Cu, Mg, and the rare earth mixture to further save energy.
  • smelting is performed in a smelting furnace, and refining is performed in a holding furnace, followed by standing still.
  • AL-5Ti-0.2B is used as a refiner for online grain refinement in an amount of 1.0-1.3 kg per ton aluminum;
  • a SNIF (Spinning Nozzel Inert Floatation) degassing device is used for online degassing, with the H content in the melt being controlled to be ⁇ 0.12 ml/100 g Al; and the melt is purified by 50 PPI plate filtration and RC grade or higher tubular filtration.
  • the flat cast slab obtained in the casting step has a fraction of loosening area of 2 ⁇ m or more in a low-magnification cross section in the range of 0.05-0.18%.
  • the flat cast slab is obtained by semi-continuous casting at a casting speed of 50-60 mm/min and a casting temperature of 660-710°C. Subsequently, the sprue portion and the starter head portion are saw-cut from the flat cast slab and milled, with the saw-cutting length of the sprue portion from the cast slab being ⁇ 150mm, and the saw-cutting length of the starter head portion from the cast slab being ⁇ 400mm.

  • the large surface of the flat cast slab is milled with a milling amount of 10-15 mm, and the side surface of the cast slab is milled with a milling amount of 8-12 mm.
  • the flat cast slab obtained in the casting step is milled and then subjected to homogenization treatment at 570-610°C for 8-15 hours, for example, 10-15 hours or 8-12 hours. Since the use of the recycled material brings in a higher content of Si and Fe, stress concentration points are formed when the coarse second phase is formed. The stress concentration points, besides inclusions, are one of the main causes of perforation defects.
  • this technical solution also allows for optimization of the degree of elemental segregation inside the cast slab, which not only avoids overburning, but also ensures that the a phase conversion ratio is greater than 80%, and the matrix structure, impurity elements and inclusions are more evenly distributed, thereby reducing the incidence of perforation defects after canning by at least 10ppm in comparison with those products manufactured by conventional processes.
  • the flat cast slab is cooled rapidly by lowering the temperature of the flat cast slab to 510-540°C at full power, and held for 2-12 hours before being discharged from the furnace and rolled. The cooling rate is controlled within 20-80°C/h.
  • the rolling step comprises:
  • a hot-rough-rolled sheet with a thickness of 30-45 mm is obtained through 19-27 passes.
  • the total reduction rate obtained after 3-5 passes is ⁇ 87%.
  • the size of the second phase in the aluminum alloy sheet for a can body is kept at 70 ⁇ m or less, thereby reducing the incidence of failure caused by perforation defects in the thin aluminum alloy sheet for a can body, and on the other hand, the manufacture of a thinner sheet is enabled.
  • the aluminum alloy sheet for a can body provided in the present disclosure may be prepared by the following method:
  • a recycled can body material of the same series, an aluminum ingot, rare earth metals and metal additives are added to prepare a batch material, wherein the recycled can body material of the same series is added in a mass amount that accounts for at least 50% of a total mass of the batch material; wherein, by mass percentage, the batch material is controlled to comprise Mn: 0.70-1.35%, Mg: 0.80-1.55%, Si: 0.30-0.50%, Fe: 0.40-0.80%, Cu: 0.15-0.35%, Zn: 0-0.30% , Ti: 0-0.08%, a rare earth mixture of Ce+La: 0.005-0.008%, and a balance of Al and unavoidable impurities; wherein the mass ratio of Fe/Si is greater than 1.5.

  • AL-5Ti-0.2B is used as a refiner for online grain refinement in an amount of 1.0-1.3 kg per ton aluminum; a SNIF (Spinning Nozzel Inert Floatation) degassing device is used for online degassing, with the H content in the melt being controlled to be ⁇ 0.12 ml/100 g Al; and the melt is purified by 50 PPI plate filtration and RC grade or higher tubular filtration.
