The ring rolling process starts with a circular preform of metal that has been previously upset and pierced (using the open die forging process) to form a hollow “doughnut.” This doughnut is heated above the recrystallization temperature and placed over the idler or mandrel roll.

Ring rolling forming process is an advanced partial loading and continuous forming technology to produce seamless ring parts. It has been well used to produce rectangular section ring parts. Compared with the ring rolling of rectangular section ring parts, ring rolling a profile ring part is more complex.
