Abstract

Abstract
The geometrical lubricating film formation on a strip in front of the rollers at dressing process is analyzed. The effect of the initial thickness of the lubricant film on the initial section of the metal deformation zone is calculated. This effect is great for low rolls gripping angle. The differential equation for extreme geometrical properties of the lubricating layerin before the initial section of the deformation zone is solved by the Monte-Carlo method.
This geometry can be achieved in dressing processes using high quality lubricants, aimed to save lubricant in the technological process. In the series of diagrams the critical point separating the optimal thickness of the lubricant film from the excess of lubricant is established. For theoretical investigations, the positioning of this critical point is of essential importance.
