Blank Thickness Effects on Rolling Force in Hot Rolling of Titanium Alloy Large Rings

Abstract:

Article Preview

For hot rolling of titanium alloy large rings, rolling force is very important for designing, choosing and optimizing of processing plan and rolling mill. In the paper, the average shape parameter of the deformation zone of ring rolling is presented first, and then a reliable coupled thermo-mechanical three-dimensional (3D) finite element (FE) model for the process is developed. Finally, influences of the blank outer radius R0 and inner radius r0 on rolling force are discussed and compared for exploring blank thickness effects. The main results show that decreasing the blank thickness by decreasing R0 or increasing r0 leads to a saving of rolling force, while R0 has a predominant effect than r0.
