Embodiment Construction
[0010] The manufacture embodiment of household aluminum foil of the present invention is as follows:
[0011] a. Smelting, casting and rolling. The raw materials are smelted and cast and rolled with low excessive casting and rolling technology. The thickness of the billet after casting and rolling is 7.0±0.2mm; the composition and weight percentage of the raw material alloy are: Si 0.2%, Fe 0.79% , Cu 0.05%, Zn 0.1%, Ti 0.05%, Al balance;
[0012] b. Cold rolling the billet thickness to 4.1mm for billet homogenization annealing, the homogenization annealing process is: under the condition of 580 ℃, heat preservation for 28 hours; after being released from the furnace, cool to room temperature, continue cold rolling, and carry out cold rolling to 0.8mm thickness Intermediate annealing, the annealing process is: under the condition of 380 ℃, heat preservation for 10 hours; then cold rolling to 0.35mm for trimming;
[0013] c. Foil-roll the trimmed material to the thickness of t...
