An ultra-thin aluminum foil production process short process, characterized in that: it is carried out according to the following process steps:

The first step, smelting: large-capacity regenerative aluminum melting furnace into molten aluminum, by chute into the casting machine, aluminum fluid flow process, refiner Al-Ti-B line addition, the formation of a continuous, uniform refine results; graphite rotor at 730-735 ℃ online in addition to gas, slag, forming a continuous uniform scavenging effect;

The second step, the rough rolling: The first step in liquid aluminum smelting introduced after casting into a billet casting machine; in this process, the cooling water inlet temperature control roller body cavity at 20-23 ℃, water temperature control 28-32 ℃, roll sutural aluminum melt static pressure control in 0.004-0.005Mpa, to ensure that the crystal orientation of {100} plane of the material rate> 95%, grain size ≤5μm, rolling out a slab 6.5-7.5mm

The third step, intermediate rolling: said cold-rolled slab unit again rolled to a thickness of 4.5mm when it is fed into the annealing furnace, heated to 360 ℃, after 2 hours incubation, heating was continued to 580 ℃ , holding 18 hours, homogenizing annealing, the grain size uniform, consistent directionality; then continue in the cold rolling mill cold rolling to 0.60mm, it again fed into the furnace, heated to 460 ℃, holding five hours after cooling to 400 ℃, 7 hours incubation, intermediate annealing; then continue rolling to a thickness of 0.3mm as foil stock

The fourth step, a foil rolling: with four roller irreversible foil rolling mill group will foil stock above 0.3mm into aluminum foil products. The ultra-thin aluminum foil production process short, low operating cost, small-scale production and investment, and production of ultra-thin foil quality can reach the international advanced level, compared to the hot rolling production process, reduce investment costs in the production of the blank two-thirds of operating costs reduced by more than half
