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
