Similarity criteria and effect of lubricant inertia at cold rolling
Modern rolling mills operate at speed requiring the consideration of inertial forces for the explanation of the behaviour of lubricant layer in the enter gap of the metal deformation zone. For this calculation a similarity criterium and the improved Mizun-Grudev equation were applied. Good results were obtained in comparison with the numerical Monte Carlo method. A significant point of the calculation is the definition of the initial state in the point of singularity.
