Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
As depicted in figs. 1 and 2, container aluminium foil of the present utility model, comprises aluminium foil layer 1, and aluminium foil layer is 3003 aluminium alloy aluminium foil layers; Aluminium foil layer 1 comprises upper strata 11 and lower floor 12, and the upper and lower are bonded to each other; Interval be evenly provided with sticky glutinous spot 2 between upper strata 11 and lower floor 12, upper strata 11 and lower floor 12 by sticky stick spot 2 bonded to each other together with; Between upper strata 11 and lower floor 12, be arranged at intervals with fusion zone 3 along aluminium foil layer long side direction, together with upper strata is bonded to each other by fusion zone with lower floor; Edge, the long limit turnover of aluminium foil layer 1 is flanging 4, and flanging 4 turns down afterwards and aluminium foil layer is fused together mutually; Adopt 3003 aluminium alloys, can make container aluminium foil realize tensile strength: 130～150MPa, percentage elongation: (product thickness 0.02～0.1mm) >=8.0%; (product thickness 0.1mm) >=13.0% or (product thickness 0.1～0.2mm) >=15.0%, effectively overcome low this problem of metallic aluminium percentage elongation; Simultaneously owing to being provided with the upper and lower, and mutually sticky glutinous by the mode of sticky glutinous spot, can not affect under the prerequisite of aluminum foil thickness, realize the laminating of the upper and lower, even if one in upper strata or lower floor there is pin hole, can not affect obturation effect, more can not occur because of pin hole the problem of cracking yet; In addition, fusion zone can make the upper and lower interval location sticky glutinous in the mode of melting, occurs in time crack or the situation of tearing, and also can stop to the position of fusion zone, and flanging effectively prevents aluminium foil crack at edge.
Container aluminium foil (3003-H24) production technology scheme is as follows:
Product processes flow chart: product chemical composition determine-burdening calculation-get the raw materials ready, feed intake-melting-refining-casting-cold rolling cogging-homogenizing annealing-cold roughing-rewinding trimming-intermediate annealing-cold finish rolling-straightening trimming-paper tinsel rolls-cuts-finished products-inspection, packs.
The crucial production process of container aluminium foil is: the operations such as chemical composition is determined, melting, refining, casting, homogenizing annealing (or intermediate annealing), paper tinsel are rolled, finished products.The technical requirement of each crucial production process is as follows:
1, chemical composition is determined: adopt inner controlling standard of enterprise control 3003 alloying components: Si0.05-0.1, Fe0.6-0.7, Cu0.05-0.08, Mn1.0-1.15, Mg0.1, Zn0.1; Al surplus.
2, melting: smelting temperature is no more than 800 DEG C, various solid material (aluminium ingot, pack fast, other waste materials) take reasonably to reduce the measure of scaling loss, after fusing, stir, and prevent component segregation, add refining agent in smelting furnace refining, control converter temperature;
3, refining: add on request refining agent in standing furnace refining again, aluminium liquid leaves standstill 15～20 minutes, then through degasification tank degasification, filtration, adds after aluminium titanium boron wire at chute, prepares production casting volume;
4, casting: the Aluminum after refining injects tilting casting and rolling machine and produces Casting Rolled Sheet (casting volume), by controlling casting-milling technology parameter (front case temperature and liquid level, roll casting speed etc.), control Microstructure of roll casting and Casting Rolled Sheet dimensional tolerance and surface quality.
5, homogenizing annealing: carry out homogenizing annealing to the cold rolling coil of 4.0 thickness on 40 tons of annealing furnaces through cold rolling split rolling method;
6, paper tinsel rolls: the cold rolling coil of thickness 0.15～0.35mm of producing through cold rolling mill is rolled down to finished product thickness (as 0.054,0.057,0.068,0.07,0.1,0.135mm etc.) on aluminium foil mill
7, finished products: annealing target: tensile strength 130～150MPa, percentage elongation >=10.0% or 13.0% or 15.0% (different-thickness is adopted to different percentage elongation standards); And when annealing, take into account aluminium foil surface oil removing.
For the container aluminium foil of different-thickness, intermediate annealing process is different:
1, the production of the container aluminium foil products of thickness 0.07～0.135mm: all move back (570 DEG C × 25h of homogenizing annealing), no longer intermediate annealing later when cold rolling thickness 4.0mm, finished product annealing process (180 DEG C × 10h+265 × 60h).
2, the production of the container aluminium foil products of thickness 0.036～0.068mm: when cold rolling thickness 4.0mm, all move back (570 DEG C × 25h), and when cold rolling thickness 1.0mm in move back (520 DEG C × 9h+420 DEG C × 6h), then add finished products (180 DEG C × 10h+260 × 60h).
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
