Rolled ring forging is a process that starts with a circular metal preform that has been pierced to form a doughnut shape. The ring is heated and rotated to reduce its wall thickness and increase its diameter.
Including titanium seamless rolled rings, forged rings, and casted rings
The process for seamless rolled forged rings involves cutting a hole out of the forging material and rolling it into a thin ring. The rolled forged rings offer concentrically improved rings with smooth surfaces as compared to plate burn-outs, or butt welded rings.
