SURFACE ROUGHNESS EFFECTS IN ALUMINIUM ROLLING
(College of Mechanical and Electrical Engineering Central South University of Technology,Changsha 410083)
Abstract: The present work on oil film thickness in rolling deformation zone was introduced briefly, and the calculation model of oil film thickness considering surface roughness effects was established by using average flow model. In addition, the effects of surface roughness and the directionality on oil film thickness were quantitatively analysed.
Key words: rolling oil film thickness surface roughness
