Abstract：

The tandem skew rolling (TSR) process of tube is developed as a new process with the short process for producing seamless tube, which combines the traditional piercing process with the tube rolling process as a two-step process. Taking 45 steel as the material of tube billet, the FE model of TSR process of tube was constructed by the finite element software Deform-3D, and the flow law and the distribution laws of stress field, strain field and velocity field for tube in TSR process were analyzed. The experiments were conducted in TSR experiment mill, the quality and dimensional precision of the rolled tube were analyzed, and the changing law of rolling force was obtained. The simulation results show that the maximum stress occurs in the deformation zones of the piercing and rolling sections respectively, especially in the contact deformation zones in TSR process of tube. The strain is distributed in layers with the increasing trend along the axial direction from entrance to exit. However, the velocity is distributed in layers with the decreasing trend along the radial direction from outside to inside. The experimental results show that the qualified seamless tubes are produced by TSR process, and the dimensional precision of diameter and wall thickness are (Φ38.18±0.4 mm) and (3.66±0.3)mm, respectively.
