Sažetak

The radial- shift mill (RSM) of a new design, which makes it possible to obtain high quality rods by the combined rolling-pressing process is proposed in this article. By using the MSC.SuperForge program the quantitative data has been obtained and main regularities of the stress-strain state distribution during rolling in smooth, helical rolls and rolling-pressing of billets on a RSM of a new design were established. Special attention is paid to the influence analysis of rolling in smooth and helical rolls and to the rolling-pressing on the formation of structures in rods from M1copper alloy. It has been established that processing by the combined process makes it possible to form a finegrained structure along the cross-section of the bars without disrupting the continuity of the billet material. By using physical modeling the effect of temperature-deformation processing modes on the kinetics of dynamic recrystallization of copper alloy M1has been studied. The dependence of the size of the recrystallized grain from temperature and degree of deformation has been established.
