Influences of Geometric Factors on Rolling Force and Moment in Hot Ring Rolling of Large Parts

摘要：

For hot ring rolling of large parts，rolling force and moment are of significance for designing,choosing and optimizing of rolling die and mill．In the study,the average shape parameter of the deformation zone of ring rolling is presented first．and then a reliable coupled thermomechanical three-dimensional(3D)finite element(FE) model for the process is developed.Finally，the influences of geometric factors on rolling force and moment during hot ring rolling of titanium alloy large parts are explored．The main results show that increasing the ratio of driver roll radius to idie rolI radius or decreasing the average radius of blank is beneficial to a saving of rolling force and moment,while the axial height of blank has a Iittle infiuence．
