Analysis of Helical Rolling Process of Balls Formed From a Head of a Scrapped Rail

Abstract: This paper presents an innovative helical rolling process of balls destined for mills manufactured 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 simulation, with t… Show more

“…The technique is based on the use of wedges with helical grooves which are mounted on the rolls to ensure that parts are formed in a continuous manner. The numerical results and experimental findings demonstrate that helical wedge rolling is a viable technique for forming balls [60,63,68,85,99,101,134,136]. Figure 19 shows the tools used in the HWR for balls and semi-finished balls.…”
