Measurement of Actual Stress and Temperature on a Roll Surface during Rolling : Development of a Sensor for Detecting Pressure and Frictional Stress

Abstract

A stress sensor for detecting pressure and frictional stress acting on a roll surface during rolling has been developed. Using this sensor, not only the pressure, but also the frictional stress in the rolling direction and in the width direction can be detected at the same time. The measuring performance of this sensor is investigated and an example of the measurement during rolling is shown. The accuracy of the measured data is confirmed.
