This paper is divided into two parts, experiments and finite element simulations. In experiments, the effects of various rolling conditions such as roll rotational speed, reduction, upon entrance and exit axial velocities, entrance and exit rotational speeds, twisting angle of rolled products are investigated. Experiments with roll rotation and planetary rotation are carried out to check the validity of the results obtained by roll rotation only. In finite element simulations, DEFORM 3D is used to simulate planetary three-roll rolling. The rolling torque, the distance between spirals, and the shape are analyzed, and the analytical results are compared with experimental results.
