Abstract
Radial-shear rolling (RSR) plays an important role in the production of titanium alloys in OAO VSMPO-AVISMA (Verkhn. Salda), having a number of advantages over other processes of metal formation. A software complex for modeling formation and heat transfer in the metal volume has been developed during this investigation on the basis of engineering computation techniques, and the rolling of a bar of the VT6 alloy with a diameter of 155 mm has been studied using it. The ThemoRSR program, making it possible to image computational data in the Mathcad environment, is developed; rolling is modeled with a DEFORM-3D package; and conditions of its application are shown. Promising methods for measuring the rolling temperature and the torsion torque on a mill spindle are considered.
