Metal state investigation in the course of radial-shear rolling in SRVP-130 mill

Abstract

Radial-shear rolling is prominent in production of titanium alloys at «VSMPO-AVISMA» Open Society (V. Salda city) and has a number of advantages over other plastic metal working processes. In the present investigation on the basis of engineering design procedures, a complex of software has been developed for forming simulation and heat transfer in the metal volume,and with its help the rolling of VT-6 alloy bar of 155 mm in diameter has been studied. «ThermoRSR» program has been developed that allows us to visualize design data in «Mathcad» medium; rolling process simulation has been carried out by means of DEFORM-3D package; and the conditions of its application are shown. Prospective ways of rolled stock temperature and rolling torque measurement are considered.
