Studies on the Three-Dimensional Distribution of Rolling Pressure in Hot Rolling

抄録

In this paper a new analysis of pressure distribution in hot rolling is made. For complexity of the problem, past investigations on the pressure distribution during the rolling are restricted to two-dimensional consideration. Then, the author develops a three-dimensional consideration of pressure distribution during the rolling by adopting the following two premises, namely the mean slipping angle is constant between the rolls and plate, and the rolling stresses states are expressed by partially approximating the yield criterion of Von Mises. Consequently, the author can explain the pressure decrease toward the plate edge by taking the new factor of plate width.
