Abstract

The paper present the results of theoretical studies on the effect on non-uniform temperature distribution over the chare length on the variation of longitudinal stresses in the rolling direction during the process of continuous rolling 70 mm-diameter bars. The studies were carried out based on the actual engineering data for 160x160 mm square cross-section charge of steel S355J0. Numerical modelling of the rolling process was performed using Forge2008®, a finite-element based computer program.
