Rolling Force in Hot Rolling of Large Rings

Abstract:

Article Preview

For hot rolling of large rings, determination of rolling force plays an important role in designing, choosing and optimizing of processing plan and rolling mill. The average shape parameter of the deformation zone of ring rolling is presented, and a reliable coupled thermo-mechanical three-dimensional (3D) finite element (FE) model for the process is developed. The effects of processing parameters on rolling force during hot rolling of titanium alloy large rings with different sizes are explored and the results obtained show that different rings follow a similar trend: increasing the relative reduction or rotational speed of the driver roll, or decreasing the feed rate of the idle roll is beneficial to a reduction in rolling force.
