Lubrication flow during the rolling of seamless tubes
An approximate analytical solution for calculating the lubricant-layer thickness for the continous rolling of seamless tubes on a long, floating mandrel was derived. In the area of nano-behaviour the geometry of the process prevails over the rheological and kinematic characteristics. The solutions were derived for tools and tubes with smooth surfaces and offer the possibility of optimizing the quality of the lubricant. In calculations of the nano-lubricant layer, the thickness is assumed to be an artificial irrational value for maintaining the continuity of the mathematical analysis. This analysis justifies the use of new geometrical characteristics for the mandrel.
