This paper presents an innovative helical rolling process of balls destined for mills manufac¬tured from a scrapped rail head. In this process, helical rolls are applied, whose construction allows obtaining a cylindrical bar, and later balls are formed from this bar in the further stage of the process. It is advised to precede the rolling process by side pressing leading to increase of billet material shape compactness. Verification of the assumed solution correctness was made using numerical sim¬ulation, with the application of Simufact.Forming software.
