Embodiment 1
[0034] A method for producing a 1100-H14 state aluminum alloy strip for processing high-end cosmetic bottle caps, comprising the following steps:
[0035] Step a: smelting, the smelting temperature is 700°C, and the smelting time is 5h; the mass percentages of the components in the smelted aluminum alloy are: Si: 0.127%, Fe: 0.393%, Cu: 0.188%, Mn: 0.0034%, Mg : 0.00085%, Ti: 0.027%, the total of other impurities ≤ 0.05%, and the rest is Al.
[0036] Step b: using semi-continuous ingot casting, the casting temperature of semi-continuous ingot casting is 715° C., and the casting speed is 55 mm / min.
[0037] Step c: the ingot is kept at 600±15° C. for 12 hours for homogenization heat treatment, and the head and tail are cut and face milled.
[0038] Step d: Heat the ingot to 530°C and keep it warm for 3 hours. Using a 1+1 hot rolling unit, hot rough rolling is performed first, and after 17 passes of rolling, the ingot is roughly rolled to a thickness of 35mm, and then hot and f...
