Did you know that a seamless rolled ring forging is a process that involves ring rolling on rolling mills? In case you’re wondering, these rolling mills come in different sizes in order to create rings with outside diameters that range from a few inches to over 300” and weights that range from 1lb. to about 300,000 lbs.
How Does the Process Work?
The process of producing seamless rolled ring forging begins with a circular preform of metal that was previously upset and pierced through the open die forging process to create a hollow donut-shaped component. The heat that is above the recrystallization temperature is applied to the donut before it is placed on the mandrel or idler roll. The donut is continuously rotated as the idler roll is moving under pressure toward a drive roll. As the donut is being rotated, its wall thickness is being reduced and its diameters are being increased.
Continuing the Process
Furthermore, different configurations can be used to produce various rings that are flat, washer-like parts or tall cylindrical shapes. In most cases, the ring ratios between wall thickness to height can range from 1:16 up to about 16:1. However, it’s important to note that it’s also possible to achieve greater proportions (thanks to special processing.)
Shaping and More
The most commonly used shape that’s known for its simplicity is a rectangular cross-section ring. But you can also use shaped tooling to create complex seamless rolled rings and custom shapes that have contours inside and/or outside of its diameters.
