Description
Technical field
The present invention relates to a kind of aluminium alloy foil material for container, the present invention also provides the manufacture method of this aluminium alloy foil material.
Background technology
Since aluminium foil have the forming process of being easy to, sterilization aesthetic in appearance, easy, with low cost, reclaim advantages such as convenient, the deep processed product aluminium-foil containers is used widely, and cutlery box, refrigerating box, the freezer that can make on the container, plate, lunch box, aircraft of the food such as fruit that are filled with water are preserved container etc.Container all requires to have advantages of higher tensile strength and unit elongation with aluminium foil, has good deep drawing quality, formability, well-pressed degree, and the even zero defect attractive in appearance of appearance luster.This kind aluminium foil often adopts the hot rolling technology to produce at present, and cost is higher.And when adopting rolling casting technology to produce, the ubiquity deep drawability is bad, and defectives such as visual appearance difference are difficult to satisfy the requirement of user for this product.
Summary of the invention
Goal of the invention: the objective of the invention is often to adopt the hot rolling technical costs too high at the prior art aluminium foil, adopt the rolling casting technology deep drawability bad, the deficiency of visual appearance difference etc., a kind of aluminium alloy foil material for container is proposed, this material has advantages of higher tensile strength and unit elongation, and having good deep drawing quality, formability, well-pressed degree, and the even zero defect attractive in appearance of appearance luster satisfies user's demand.
Another object of the present invention provides a kind of method that adopts rolling casting technology to make this material.
Technical scheme: for achieving the above object, aluminium alloy foil material for container of the present invention, the component and the weight proportion that it is characterized in that this material are: iron 0.42-0.52%, silicon 0.05-0.20%, copper 0.04-0.13%, manganese 1.10-1.30%, titanium 0.020-0.040%, all the other are aluminium.
The manufacture method of aluminium alloy foil material for container of the present invention is characterized in that this method may further comprise the steps:
1) casting of slab: the remelting that will get ready according to the above ratio is with fusing in commercial-purity aluminium ingot, ferro-aluminum intermediate alloy ingot, aluminium silicon intermediate alloy ingot, aluminum bronze intermediate alloy ingot and the aluminium manganese intermediate alloy ingot adding smelting furnace and be warmed up to 700-760 ℃, by refining, slagging-off, stirring, analysis and adjust that composition is laggard goes into to leave standstill stove, described leave standstill in the stove leave standstill, refining, degasification, slagging-off; Aluminium liquid is derived and is left standstill stove, enables the fining agent adding set in chute, and behind the titanium elements of the described ratio of adding, degasification and filtration outside stove enter the casting of casting unit again in aluminium liquid, and it is the slab of 5.0-8.0mm that casting becomes thickness;
2) described cast-rolled block is carried out preannealing, annealing temperature is 500-600 ℃, and the cast-rolled block metal takes out after 2-3 hour to the maintenance of temperature back, is cooled to normal temperature;
3) with the thick sheet material of cast-rolled block cold rolling one-tenth 1.6-2.0mm;
4) sheet material that described 1.6-2.0mm is thick is placed on and carries out process annealing in the annealing furnace, and annealing temperature is 300-350 ℃, and sheet material keeps taking out after 4-5 hour to temperature, is cooled to normal temperature;
5) the thick plate rolling of 1.6-2.0mm that will be cooled to normal temperature on cold-rolling mill becomes the thick foil of 0.08-0.14mm;
6) foil that described 0.08-0.14mm is thick is placed on and carries out finished products in the annealing furnace, and annealing temperature is 320-360 ℃, and sheet material keeps taking out after 4-5 hour to temperature, is cooled to normal temperature;
7) foil that will be cooled to the 0.08-0.14mm of normal temperature is placed on and carries out oiling on the oiling shears and shear, and makes aluminium alloy foil material for container of the present invention.
In order to guarantee the casting quality, guarantee to have to meet and be scheduled to crystal structure and template etc., in the strip casting process of step 1), the casting section length is 40-50mm, and preceding oven temperature, degree is 680-690 ℃, and roll casting speed is 800-1000mm/min.
For the microstructure of improving aluminium foil and the distributional pattern and the structure of the second phase particle, the fining agent that uses in step 1) is aluminium titanium boron wire.
In order to reduce the coefficient of friction of aluminium foil surface, help aluminium foil and when punch forming, do not ftracture, in step 7), be coated with one deck edible lubricating oil at aluminium foil surface.
3, beneficial effect: the present invention compared with prior art, its remarkable advantage:

6Compound, favourable to the unit elongation that improves alloy; Simultaneously, Fe content is higher and add Ti, produces uneven texture of coarse crystal when helping preventing high temperature annealing, is beneficial to the unit elongation that improves alloy.In conjunction with the manufacture method of above-mentioned uniqueness, its final performance index can reach customer requirements simultaneously.
2) the present invention is added into the aluminium titanium boron wire fining agent before casting, has improved the microstructure of aluminium foil and the distributional pattern and the structure of the second phase particle.
3) the present invention has added preannealing technology before cast-rolling stock is cold rolling.Because speed of cooling was very fast during casting-rolling technology was produced, and caused the solid solution of a large amount of Mn atom in aluminum substrate, form supersaturated solid solution.The existence of solid solution Mn atom not only can increase because of solution strengthening makes aluminum substrate intensity, improves resistance to deformation.And through follow-up cold roller and deformed after, owing to have interaction between solute atoms and dislocation and crystal boundary, it is poly-partially that solute atoms is tended in dislocation and crystal boundary place, slippage to dislocation plays inhibition with the migration of climbing with crystal boundary, thereby be unfavorable for the forming core of recrystallize, and then improved recrystallization temperature.And under hot conditions, carry out recrystallization annealing, and very easily cause grain growth, be difficult to obtain that crystal grain is tiny, the aluminium foil tissue of homogeneous microstructure.
Cast-rolling stock is separated out a large amount of fine particle shape second phase compounds through behind the preannealing in the casting plate, sosoloid decomposes, and separates out the Mn element, and along the synusia shape second phase compound generation nodularization of crystal boundary distribution, it is more even to distribute.Make the casting plate have and the similar structural state of hot rolling ingot, be easy to the recrystallization annealing Microstructure Control.
4) the present invention has been coated with edible lubricating oil at aluminium foil surface, has greatly improved the deep drawability of aluminium foil.
In sum, aluminium alloy foil material for container of the present invention is under same thickness, and product has advantages of higher tensile strength and unit elongation, and has good deep drawing quality, formability, well-pressed degree, and the even zero defect attractive in appearance of appearance luster, satisfies user's demand better.
