Abstract

The analysis of kinematic and deformation characteristics of metal flow in the deformation zone during rolling is carried out, the characteristics of metal flow in the range of large and small values of the reduction ratio are revealed. Analysis of the kinematic features for large values of the reduction ratios can broaden our understanding of the metal flow laws and enables to obtain additional information to the disclosure of the unsolved questions in rolling theory.

Keywords: ROLLING, PARAMETERS, DEFORMATION ZONE, STICKING, FORWARD SLIP, REDUCTION RATIO
