Friction measurement in cold rolling

Abstract In order to study friction in the roll bite in the laboratory, a work roll with embedded pins is used in cold rolling. Friction and pressure are studied under dry and lubricated conditions. Aluminum alloy is used in the experiments. The results confirm that the friction coefficient in the roll bite is not uniform. The validity of the experimental data is confirmed by comparing it with theoretical results. This indicates that the sensor roll can give reliable friction measurements.
