Definitions
- the production of aluminum foils by first cast a billet of aluminum or aluminum alloy, the ingot is hot rolled into a hot strip and then the hot strip is cold rolled by cold rolling with or without intermediate annealing to final thickness of the aluminum foil or from a casting belt by cold rolling with any heat treatment.
- the rolling ingot can be subjected to a heat treatment or a homogenization according to choice before hot rolling.
- the aluminum foil is preferably double-cold rolled and doubled again before winding onto a coil. After cold rolling or doubling the aluminum foil is usually trimmed, cut to size and wound into a coil. During further processing, the aluminum foil thus produced is then unwound and subjected to a pretreatment.
- the aluminum foil is subjected to a heat treatment in heat treatment stations 7, with which in particular the rolling oil is removed from the surface of the aluminum foil 1.
- An annealing of the aluminum foil does not necessarily have to take place at this point, so that even hard-rolled, coated aluminum foils 1 can be produced.
- the heat treatment at the heat treatment stations 7 can also be used to accelerate grafting of the molecules applied to the aluminum surface.
- the surface of the aluminum foil 1 can respond to the different requirements in the further processing for the production of, for example, composite materials or packaging materials immediately after the production of the aluminum foil 1 be prepared. Additional unwinding, coating and / or winding processes for pretreatment of the aluminum foil for further processing are no longer necessary in this respect.
- the aluminum foil can also be cold rolled to final thickness and coated according to the invention.
