The process of closing defects in 12% Cr austenitic stainless steel by radial shear rolling on an RSP 10-30 mill was investigated. The advantage of radial shear rolling over other rolling methods is that it is an efficient way of achieving a high monotonic uniform deformation of the steel. The rolling sample was taken as an ingot of 12X13 steel with a diameter of 30 mm and a length of 150 mm. For mathematical research of the trough defects behavior in the radial-slide rolling mill calculation model was carried out in the software package Deform-3D. In the ingot were simulated transverse defects of different diameters and depths with initial diameter d0 of 5 mm and 2.5 mm and initial depth h0 of 5 mm and 2.5 mm and one through. The simulation aim was to compress the ingot from a diameter of 30 mm to a diameter of 15 mm with the step of rolling by 1.5-2 mm. Based on FEM modeling the evolution of defects in various intermediate stages of radial-shear rolling has been analyzed in order to investigate the possibility of defect closing.
