Abstract: A mathematical model for wide magnitude and high speed aluminum foil 4-roll mill was established by considering the theories of roll system elastic deformation, roll thermal deformation and distribution of tension stress. Using the model, the shape and cross section profile of aluminum foil rolled were simulated, and the theoretical results are very close to the experimental ones. The theory has very important significance for studying the influence of technical parameters on the shape and improving the controlling accuracy of the foil shape.
Key words: aluminum foil roll system elastic deformation roll thermal deformation shape
