Primer on Flat Rolling

Rolling mill work rolls impart the rolled strips with their finished surface quality. In order to make this repeatable, the roll surface quality must retain its as-ground surface for as long as possible. Modern mills have moved to rolls with a high-strength steel chemistry to minimize the wear conditions of the work rolls with time in the mill.
