Sažetak
The mechnism of the salt phosphate lubricant ingress in zone of the tube deformation on a long cylindric mandrel was considered. Suggested mathematical model is based on the points of the hydrodynamic theory of lubrication. Data presented are concerned with a value of a salt lubricant layer thickness and friction factor between metal and mandrel at continuous hot rolling of tubes.
