We describe the results of a full-scale experiment in the fabrication of 957 mm diameter railroad wheels from a pre-formed hollow billet obtained by piercing a thick-walled sleeve with an ingot. We found that a 474 mm diameter steel wheel billet can be smoothly pierced using a rotary piercing mill. The process of forming hollow billets when mass-producing wheels in press-rolling equipment also remains stable. The mechanical specifications of railroad wheels fabricated from hollow billets meet regulatory requirements.
