  • Improvement of rolled strip surface and geometry by advanced automatic diagnosis of surface defects and optimisation of friction in the roll gap

Abstract

Modelling of some aspects of defect formation through different passes in a hot strip mill was conducted, but further work required characterisation of friction in the roll gap. Hot plane strain compression testing gave mean friction results of limited applicability. Tests using an experimental hot friction test rig allowed derivation of a variable friction relationship used in a model of the first finishing pass.
