Аннотация: The scheme of plastic deformation of a billet in a container is considered as part of continuous extrusion by the Conform method. A mathematical model of the motion of a viscoplastic Bingham liquid is used to determine the metal velocity distribution in the plastic-deformation zone. As a result, the optimum angle between the longitudinal axes of the die and container is estimated. This angle is found to be one of the main factors affecting the nonuniformity of deformation when a metal flows into the die. The calculated results are compared to experimental data. © Pleiades Publishing, Ltd. 2010.
