Studying the Nonstationary Stages of Screw Rolling of Billets with Profiled Ends

摘要

The rolling of VT-6 alloy billets with profiled ends in a screw rolling mill is studied to determine the geometry of the end sections minimizing the funnel depth after rolling. The rolling experiment conducted is of 2(3) factorial design. The nonstationary stages of the process are simulated using Deform-3D software. The results of the simulation are used to find the shape and dimensions of the end sections of the billet that minimize the funnel depth.
