What is the role of aluminum foil stack rolling (double rolling)?

Aluminum foil rolling produces plastic deformation under the conditions of roll-free rolling. At this time, the rolling mill frame is elastically deformed and the rolls are elastically flattened. When the thickness of the rolled piece reaches a smaller and more limited thickness h. When the rolling pressure has no effect, it is very difficult to make the rolled piece thinner. Usually two pieces of aluminum foi ...
