1.6981 21CrMoNiV4-7  Metal Forgings EN10269 Forged Rings

 

Forged Rings Introduction


The ring rolling process starts with a circular preform of metal that has been previously upset and pierced (using the open dieforging process) to form a hollow “doughnut.” This doughnut is heated above the recrystallization temperature and placed over theidler or mandrel roll. This idler roll then moves under pressure toward a drive roll that continuously rotates to reduce the wall thickness, thereby increasing the diameters (I.D. and O.D.) of the resulting ring.


Seamless rolled rings can be produced in configurations ranging from flat, washer-like parts to tall, cylindrical shapes, with
heights ranging from less than an inch to more than 9 feet. Wall thickness to height ratios of rings typically range from 1:16 up to 16:1, although greater proportions can be achieved with special processing. The simplest and most commonly used shape is a rectangular cross-section ring, but shaped tooling can be used to produce seamless rolled rings in complex, custom shapes with contours on the inside and/or outside diameters.
