摘要	A 3D finite element method is used to the simulation of cold pilgering process of 1Cr18Ni9Ti stainless steel tubes by using ANSYS software, which are cast by electromagnetic centrifugal casting (EMCC) and of the characteristic of composite structure. Simulation results show that during cold pilgering the better the axial plasticity of tubes, the smaller the shear stress sigma(rz), and the shear strain epsilon(rz), as well as the better the property of rolling deformation. Along with the decrease of the Coulomb friction coefficient not only the sigma(rz), and the epsilon(rz), are decreased, but also the discontinuity Of sigma(rz), between outer columnar and inner equiaxied zone is decreased. Moreover, the property of rolling deformation and the quality of tubes are improved. With the increase of exciting currents, which enlarges equiaxed zone, not only the mechanical property of the tubes is improved, but also the sigma(rz), and the epsilon(rz) are decreased. Moreover, the property of rolling deformation and the quality of tubes are also improved. The simulation results agree well with the experiment.
