The project is focused to achieve higher product quality and productivity on rolling mills, it becomes necessary to get a profound knowledge of friction, heat transfers and lubrication in the roll gap. An approach is proposed to develop innovative roll gap sensors to measure simultaneously at the roll-strip interface thermal and mechanical conditions and oil film thickness: different sensor designs are evaluated and compared in hot and cold rolling using laboratory, pilot and industrial mill tests. Finally the sensors, combined with modelling and mill measurements, are used to increase mills productivity (lower roll surface degradation) and to improve product quality (better strip thickness).
