The ring rolling device has a ring template (9) to receive the semifinished workpiece (10), at least one adjustable axial roll (20,21) and additional adjustable rolls (24,25). The additional rolls consist of a first roll (24), mainly for displacing inwardly projecting workpiece material axially into the template, and a separate second roll (25), mainly for rolling out the displaced material to the required internal measurement of the ring.
