Study of the Mean Roll Pressure in the Hot Rolling Process

Abstract

This paper presents an approximate method of calculating the mean roll pressure in the hot rolling of rods and flat plates with finite width. The equetion is proposed as follows, [numerical formula] This is checked against measurements made when rolling some rods and flat plates. There is fairly good agreement between the calculated and the measured values. Moreover, the results calculated from this equation nearly agree with the values obtained from Sims'formulae where the ratio width/thickness for the material is infinite.
