Steel Forged Rings Introduction

 

Seamless forged rings can be produced by a process called ring rolling. Ring roll production begins with a circular preform of metal that has been pierced (using the open die forging process) to form a “ring blocker”. This blocker is then reheated to the proper temperature for that grade of material and placed over a mandrel. The mandrel then moves to a drive roll (king roll) that rotates under pressure to reduce the wall thickness, thereby increasing the diameters (I.D. and O.D.) of the ring forging.

Depending on the size, seamless rings can also be produced by simple piercing of a forging, either open die or with the outside diameter contained in a tool. Other manufacturing methods such as mandrel rolling under a hammer or press or drawing the material over a mandrel bar. We uses all of these methods to produce seamless forged rings of the highest quality and integrity.
