Measurement of Actual Stress and Temperature on the Roll Surface During Rolling : Frictional Stress Distribution and Pressure Distribution in Cold Rolling

概要

論文の詳細を見る
Pressure, and frictional stress in both rolling and width directions have been measured in the cold rolling of aluminum strip and billet by a new stress sensor developed by the authors. Characteristics of the frictional stress distribution in cold rolling have been elucidated. Frictional stress in the rolling direction is almost constant from the entrance to the neutral point in the contacting arc, both in strip and billet rolling. by contrast, frictional stress in the width direction increases from the center line to the edge part and its peak lies in the central part of the contacting arc in strip rolling. However, in billet rolling, it has two peaks along the contacting arc and its value does not vary from the center line to the edge part. This may be connected with the metal flow in the width direction in billet rolling.
