Measurement of Actual Stress and Temperature on the Roll Surface in Rolling : 1st Report, Development of a Sensor for Detecting Pressure and Frictional Stress

Abstract

A stress sensor for detecting pressure and frictional stress acting on the roll surface in rolling has been developed. Using this sensor, not only pressure but also frictional stress in the rolling direction and frictional stress 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 in rolling is shown. The accuracy of the measured data is confirmed.
