For the optimizations in the rotating die drawing of wire rod, the DEFORM-3D commercial software is used to do the FEM simulation; the frictions between dies and wire rod are assumed to be constant shear friction to obtain the effective stress, the effective strain, the velocity field, and the drawing force. The assembly of simulation experimental parameters can be determined to reduce the drawing force and die stress, as well as to increase the velocity at exit and drawing efficiency.
