Description
A METHOD FOR ROLLING OF AN ALUMINUM ALLOY STRIP AND AN
ALUMINUM ALLOY STRIP, SHEET AND FOIL
Description
The object of the invention is a method for rolling of an aluminum alloy strip and an aluminum alloy strip, sheet and foil.
The process of rolling of an aluminum alloy strip may lead to an end product in a form of an aluminum strip, i.e. a continuous layer of aluminum having thickness of above 0,2 mm, or of an aluminum sheet, i.e. a plate of specific dimensions, or of aluminum foil, i.e. a continuous layer of aluminum having a thickness of below 0,2 mm.
Aluminum alloys, due to their properties, especially ductility, are widely used for manufacturing of metal containers. Properties of alloys depend on their chemical composition as well as the method of their manufacturing. One of the alloys of a known and typical composition, the 8011A type defined by a Polish standard PN-EN573, comprises, in addition to aluminum, additives of silicon Si between 0,4 -0,8 % by weight, ferrum Fe at 0,5 -1,0 % by weight and admixtures of manganese Mn, magnesium Mg, copper Cu, chromium Cr, each at 0,1 % by weight.
Properties of aluminum alloys depend in particular on the chemical composition of a solution and on the crystal composition and structure, mainly the amount and distribution of intermetallic diffusions at grain boundaries. Typical processes of continuous casting (in short CC) of known aluminum alloys provide alloys having a dendritic structure, which defines the high alloy heterogeneity, diverse amount of diffusions and their distribution. Such a structure of the material affects the end properties of a product, typically a rolled strip. The differences in microcrystal structure lead to large differences in plasticity and strength properties of known alloys.
Another aluminum alloy, the 7475 type, known from a Polish patent specification PL 194380 entitled "METHOD FOR OBTAINING AN ALUMINUM ALLOY OF 7475 TYPE IN A SUPERPLASTIC STATE HAVING A FORM OF A BILLET", comprises, apart from aluminum, admixtures of Zinc Zn at 5,85 % by weight, copper Cu at 1,65 % by weight, magnesium Mg at 2,4 % by weight, zirconium Zr at 0,4 % by weight, as well as silicon Si and ferrum Fe at less than 0,1 % by weight. In order to improve the properties of the alloy in the superplastic state, the alloy is subject to thermo-chemical processing, wherein the processing comprises a step of homogenization at temperatures of 480-520°C ended by hyper-quenching in water at room temperature, a step of age hardening at 380- 420°C ended by hyper-quenching in water at room temperature, a step of plastic straining with heating and ended by a step of recrystalisation of the strained sample in a salt furnace at 470-490°C.
The alloys described above are not plastic enough and therefore are not suitable for manufacturing of strips nor sheets of high plasticity, nor foils, in particular for food industry.
As a result of performed trials, it appeared unexpectedly that by modifying the chemical composition of the 8011A alloy it is possible to obtain a new aluminum alloy, which is the object of the present invention, suitable for manufacturing of strip, sheet or foil, having grain refined structure and high plasticity. Such properties are highly desired when the strip is used to manufacture foil, for example foil used as food packaging for various product shapes.
The object of the invention is a method for rolling of a strip of an aluminum alloy, comprising the steps of subjecting of a continuously cast strip made from an aluminum alloy comprising, except aluminum Al, silicon Si at 0,4 -1,0 % by weight, ferrum Fe at 0,35-1,2 % by weight, beryllium Be at 0,02 -0,1 % by weight, manganese Mn at up to 0,15 % by weight, magnesium Mg at up to 0,15 % by weight, copper Cu at up to 0,1 % by weight, Zinc Zn at up to 0,1 % by weight, titanium Ti at up to 0,1 % by weight, wherein the ratio of percentages by weight of beryllium Be to titanium Ti [Be/Ti] is in the range of 0,6 to 2,0 and wherein the ratio of percentages by weight of ferrum Fe to silicon Si [Fe,Si] is in the range of 0,9 to 1,1 to a stabilizing thermal treatment at over 400°C for over 2 hours, straining the strip by performing three cold rolling processes to a relative strain level between 20% and 80%, the first and second rolling processes followed by a thermal treatment at a temperature over 400°C and the third rolling process followed by a thermal treatment at a temperature 280-400°C.
Preferably, the rolling process may be continued until a rolled strip is obtained having an output thickness of above 0,2 mm, and next the strip is rolled up into a roll.
Preferably, the rolling process may be continued until a rolled foil is obtained having an output thickness of below 0,2 mm, and next the foil is rolled up into a roll.
Preferably, the manufactured rolled strip is cut into sheets.
The object of the invention is also a rolled strip, sheet or foil manufactured by the method according to the invention.
The object of the invention is shown in a preferred embodiment on a drawing, in which Fig. 1 presents a diagram of a method for manufacturing of a rolled strip from a strip cast from an aluminum alloy, Fig. 2 presents a chart of relative elongation A[%] of the strip of AIFeSiBe alloy depending on temperature and time of the thermal treatment, Fig. 3 shows a chart of average grain size in the direction of rolling in the strip of AIFeSiBe alloy depending on temperature and time of thermal treatment, Fig. 4 presents a chart of apparent yield point Rp02 [MPa] of the strip of AIFeSiBe alloy depending on temperature and time of the thermal treatment and Fig. 5 shows a chart of tensile strength Rm [MPa] of the strip of AIFeSiBe alloy depending on temperature and time of the thermal treatment.
The input material for manufacturing the rolled strip is a cast aluminum strip having a thickness lower than 10 mm, cast in a continuous casting technology and subject to thermal stabilization from an aluminum alloy comprising in principle silicon Si at 0,4 -1,0 % by weight, ferrum Fe at 0,35-1,2 % by weight, beryllium Be at 0,02 -0,1 % by weight, manganese Mn at up to 0,15 % by weight, magnesium Mg at up to 0,15 % by weight, copper Cu at up to 0,1 % by weight, Zinc Zn at up to 0,1 % by weight, titanium Ti at up to 0,1 % by weight, wherein the ratio of percentages by weight of beryllium Be to titanium Ti [Be/Ti] is in the range of 0,6 to 2,0 and wherein the ratio of percentages by weight of ferrum Fe to silicon Si [Fe,Si] is in the range of 0,9 to 1,1, whereas the remaining ingredients are aluminum Al and unavoidable slight impurities.
The material for manufacturing the rolled strip, according to Fig. 1, is subject to cold rolling process with simultaneous thermal treatments. The rolling process may be performed until an output thickness of above 0,2 mm is obtained, thereby resulting in an end product in a form of a rolled strip. The rolled strip may be next cut in order to obtain sheets. The rolling process may be furthermore conducted until obtaining an output thickness of below 0,2 mm, thereby resulting in an end product in a form of a rolled foil. The rolling process results in hardening of the alloy whereas after reaching a certain level of hardness, at which fracturing starts, the rolling is stopped and the thermal treatment starts. The thermal treatment causes recrystallization or partial recrystallization of the alloy, lowers mechanical properties and rebuilds the alloy structure, which allows for obtaining high plasticity in the final product. The process is executed in an annealing furnace.
Before the rolling process, the strip 102 having a thickness from 3 to 10 mm, after casting 121 at an apparatus for continuous casting, wherein a liquid alloy 101, having the composition as mentioned above, in short the AIFeSiBe alloy, is fed by an input nozzle 110 between two rollers 111 which are cooled by water from inside, is subject to stabilizing thermal treatment 122 at a temperature over 400°C for over 2 hours. Next, the strip 103 after stabilizing thermal treatment is subject to cold rolling 123 in a roller 112. After reaching the strain level between 40% and 80% the rolling is stopped and the aluminum alloy strip 104 is subject to further thermal treatment 124 at a temperature over 400°C and next subject to further cold rolling 125 between rollers 113, until reaching strain level between 30% and 60%.
After a still further thermal treatment 126 at a temperature over 400°C, the final cold rolling stage 127 of the strip 105 commences between rollers 114, that causes a strain level between 20% and 50%, until a strip of thickness of above 0,2 mm or a foil of a thickness of below 0,2 mm is obtained. After the rolling, the strip or the foil 106 is subject to final thermal treatment 128 at a temperature between 280-400°C, and then it is rolled up into a roll in a rolling process 129 or cut into sheets 107 in a cutting process 130.
As a result of the above method of manufacturing, the final thermal treatment causes that the strip is subject to recrystallization with creation of new fine-grained structure. The size of metal grains is lowered by several tirries.
Simultaneously, a 10-times improvement is obtained with respect to the relative elongation of the strip, lowering of the tensile strength from about 160 MPa to about 100 Mpa, lowering of the apparent yield point from about 140 MPa to about MPa and increase of the relative strip elongation from about 2% to 35%. This means that the presented process results in grain refined structure and plasticity of the strip measured with relative elongation of over 30%.
The effects described depend on temperature and time of the thermal treatment and are depicted in Fig. 2 -5. Fig. 2 presents a chart of relative elongation A[%] of the strip of AlFeSiBe alloy depending on the temperature and time of the thermal treatment, Fig. 3 shows a chart of average grain size in a direction of rolling in the strip of AlFeSiBe alloy depending on the temperature and time of the thermal treatment, Fig. 4 presents a chart of apparent yield point Rp02 [MPa] of the strip of AIFeSiBe alloy depending on the temperature and time of the thermal treatment and Fig. 5 shows a chart of tensile strength Rm [MPa] of the strip of AIFeSiBe alloy depending on the temperature and time of the thermal treatment.
As a result of x-ray phase analysis it has been found that the main phase components of the strip of the AIFeSiBe alloy are releases of phase A14.oi (MnFe1 )Sio.74 together with a slight amount of free-standing silicon Si in aluminum ground mass.
As a result of laboratory test of foil microstructure of the strip of AlFeSiBe alloy it has been found that the final thermal treatment of the strip leads to lowering of the size of grains accompanying restoring of new fine-grained structure in a recrystallization process. The average size of a grain of the strip not thermally treated is about 140 pm and as a result of the recrystallization it lowers by 2 times reaching the size of about 70 pm. The observed effect of lowering grain size is caused by decomposition of coarse-grained, strained metal structure with creation of new fine-grained recrystallized structure.
Maintenance of precise parameters of the thermal treatment allows for keeping strength properties of the strip at a required level. The process of final thermal treatment is performed with a use of a continuous furnace.
