AB  - This paper presents the results of research works concerning processing of scrapped rails heads into bars with circular sections in the elongating forging processes. The formed semi-finished products will be used as billet in the cross-wedge rolling and skew rolling processes of balls applied in ball mills. Numerical analysis were made with the application of finite element method (FEM) in the conditions of three - dimensional state of strain, using the commercial software DEFORM 3D. The shape of rolled semi-finished products was analyzed in calculations, temperatures distributions and the process force parameters were determined. The possibility of using forging techniques for the processing of worn out rails was also confirmed. The results of numerical simulations were verified in industrial conditions.
