If you want to know more about how seamless rolled rings are produced and the common materials that are used to make them, you’ve come to the right place. The entire process begins with the creation of a preform workpiece via the open die forging method. Through the use of this method, a piece of stock is processed to align the metal’s grain flow before a hole is punched in its central part. Creating the hole enables the manufacturer to place the component in the ring mill. Once placed in the ring mill, the workpiece is rotated by an idler roll while it applies pressure to the ring’s inside part. At the same time, the driver roll is used to apply pressure to the outside part of the ring. During the process, the ring’s diameter increases while the material flattens and two axial rolls control the ring’s height. This continues until the desired diameter is attained.
Many manufacturers across the globe turn to alloy steel for projects that require strong, hard, and tough rolled ring forgings. In most cases, the most popular alloy steel options include 4130, 4140, and 4340. It’s important to note that you may need to use additional heat treatments for specific types of alloys in order to achieve your desired ring quality.
Stainless steel is widely used for seamless rolled rings because of its physical and chemical properties which include strength, stability, durability, and resistance to heat as well as corrosion.
Carbon is another material that’s widely used for rolled ring forgings. However, when more of this material is added, cracks may occur and the material may become more challenging to deform and weld.
