The paper, written by Lublin University in Poland, describes an innovative technological solution for producing balls from scrap rail heads.
The proposed method consists in performing the following operations:
- the side pressing of a rail head to increase shape compactness,
- a process for forming a cylindrical rod by cross wedge rolling (CWR),
- quenching of the produced balls.
Tools for the above manufacturing operations are designed, and numerical simulations are performed with FORGE® to verify whether the assumptions of the proposed technique are correct. A flat-wedge reversing mill is designed and constructed that enables performing the two abovementioned rolling operations without idle running, which makes the design innovative on a global scale.
The implementation of the proposed method would enable producing balls for grinding media used in ball mills.
