The process control for finishing rolling is divided into three phases, mill setup, realtime control, and setup model learning. Mill setup presets the initial settings of the mill parameters such as roll gap and roll speed using a mathematical setup model before a sheet bar (at roughly 1100°C in temperature for mild steel) enters the process.

Roll Design1. John G. Lenard, in Primer on Flat Rolling (Second Edition), 2014 Friction and Wear. Work rolls in hot strip mills wear due to friction between the roll surface and hot strip. (Backup rolls wear as well, but under pressure with elastic deformation, the friction is much less, except for the high work roll roughness in the last stand of a sheet rolling tandem cold mill).
