The general process flow of double zero aluminum foil produced by the casting and rolling method is: aluminum ingot → melt smelting (sampling analysis, refined refining, slagging and inverting the furnace) → heat preservation and standing (refining, degassing and slagging) → inverting the furnace → online refining ( Degassing, adding grain refiner, filtering) → Front box (hydrogen measurement, spectral analysis) → Casting (two-roll casting) → Billet cold rolling (rough rolling) → Homogenization → Cold rolling → Intermediate annealing → Cold rolling → Middle rolling (surface annealing) → Coiling (double bonding, trimming) → Foil rolling → Sub-coiling → Finishing annealing → Quality inspection → Packaging.

When the mother roll of double zero aluminum foil are produced, the basically principle of slag removal is to rely on the density difference firstly and to use compound slagging, the effect of density difference, flotation slagging, and solvent dissolution to initially remove slag. However, there are many small and highly dispersed inclusions in the aluminum melt. If these inclusions are not removed, it will be difficult to produce high-quality aluminum foil blanks.
