Fundamental concept of metal rolling

•The friction varies from point to point along the contact arc of the roll. However it is very difficult to measure this variation in µµµµ, all theory of rolling are forced to assume a constant coefficient of friction . •For cold-rolling with lubricants, µµµµ~ 0.05 –0.10. •For hot-rolling , µµµµ~ 0.2 up to sticky condition.

Simulation of the energy-force parameters of pinch-pass mills

A procedure is proposed for the calculation of the energy-force parameters of pinch-pass mills; it does not use the hypothesis of constant instantaneous volumes, which is employed in the computation of most plastic-deformation processes. Elastic regions occupy the major portion of the deformation zone of a strip subjected to skin rolling; therefore, a static friction model is taken as a model ...
