Hot tolled ring forging is a metalworking process that begins with a circular preformed piece of metal that has been upset and pierced to form a doughnut-like shape. The temperature of the doughnut shape(torus) is heated to a point above the recry-stallization temperature and placed over a mandrel or idler.
The idler moves the pierced doughnut shape toward a drive roller that evenly, continuously, and uniformly rotates to reduce the wall thickness of the torus while increasing its inner and outer diameters. The results of the process called a seamless rolled ring.
To use this rolled ring forging process, the seamless metal rings can have varying sizes and are manufactured for use as parts of machine tools, turbines, and pressure vessels. Rolled ring forging significantly affects the mechanical properties of the material being shaped while allowing it to maintain its grain structure.
