Aluminium Coils/Foils Annealing Processanneal Technology
The aluminum coils/foils processanneal technology, should be determine according to the requirement of the state of alloy.
Blank annealing (also known as pre-annealing)
Hot-rolled slabs are generally subjected to blank annealing before cold rolling. While the cast slab does not require blank annealing.
Intermediate annealing is to point to in the process of cold deformation on the annealing.
The last annealing after the strip is rolled to the finished product thickness is called finish annealing.
