Tribology of cold metal rolling
Work is in progress to understand the mechanisms and to develop theoretical models for surface finish
generation and friction in metal rolling. Work on aluminium rolling, sponsored by EPSRC, Alcan and ALSTOM,
focuses on modelling of friction in conventional rolling and the surface finish generation in pack rolling
[1-5]. Recent work has considered the details of the roughness spectra found in practice: it is found that
short wavelengths are difficult to eliminate. This tribological model has been coupled into a mechanical
model for foil rolling, where the rolling load is particularly sensitive to friction [6, 7]. Work on
stainless steel, sponsored by EPSRC, Corus and Avesta Sheffield, concentrates on modelling the elimination of
pits of voids which arise from the shot blasting and pickling process used before the finishing passes [8,
9].
