Abstract:The surface of the aluminum foil rolled has been observed with microscope on the basis of industrial experiments, and the structure of the surface adsorption film has been analyzed by means of low angle X-ray diffraction. It is advanced that the lubrication in aluminum foil rolling is in the state of thin film lubrication, surface adsorption film is an ordered multi-layered molecule film with more than 7 layers; and the layers of the ordered molecule film is influenced by the concentration of the additive in certain range; the concentration of the additive in oil is the main factor affecting the stability of rolling, controling the concentration of the additive can control the ratio of fluid friction, boundary friction, and local holding-on in deformation zone, thus obtaining good rolling deformation conditions.

 

Key words: aluminum foil ordered multi-layer molecule film rolling deformation
