Facts About Seamless Rolled Ring Forging

How the Process Begins

The ring rolling process begins with a circular metal piece that is perforated or punctured to create a doughnut-shaped material. Once the ring is created, it is placed in a high temperature for the recrystallization process to start. From there, it proceeds to the idler roll and moved towards the drive roll. This process causes the forging to rotate and widen its diameter. The wall thickness of your rolled rings is also enhanced. To produce a seamless ring, there are various ranges of configurations that are synthetically made with the use of a shaping tool. Examples of configurations are small parts resembling washers and tall cylinders. The last step in the process focuses more on the desired size to be achieved. The rolled ring process will continue to progress until the precise size is achieved. Hence, it is essential to know your desired size before starting the forging process.

Usage and Where Can It Be Found

Seamless rolled ring forging is used for valves, robotics, machines, glass-lined reactors, gears, flanges, drives, couplings, clutches, and bearings. Additionally, you can find these materials being used by the military, in oil industries, power generation, as well as, for mining purposes. Because of this superb power generation, seamless rolled rings are also used in railways, windmills, jet engines, and power rock crushing equipment.

Rolled Rings | Types of Industries That Use Forged Rolled Rings

Forged rolled rings can have outside diameters that range from 2 to 110 inches. They can also weigh as much as 50,000 pounds or as little as a pound. The process of creating these parts involves piercing a metal preform that’s circular in shape in order to create a donut-shaped component. Next, the heat that’s beyond the required temperature for recrystallization is applied to the part before placing it over the mandrel roll or idler. As the roll is moved in the drive roll’s direction, it continuously rotates until the desired ring size is achieved.

Rolled Ring Forging’s Ability to Create Higher Ratios

Thanks to the rolled ring forging process, it’s possible for identical and exact products to have a higher ratio. This is done through a fixed process that involves punching a hole into the central part of a piece of metal. This metal is at its malleable state after going through a heating process. Once the metal component has been pierced, the manufacturer places it between the inner and outer diameter rings. Both rings will be pressed against the donut-shaped metal in order to stretch the diameters until the required thickness is achieved. In most cases, the ratio of the wall thickness to its height could be anything from 1:16 to 16:1.

Seamless Rolled Rings | Materials Used for Rolled Ring Forging

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.

Seamless Rolled Ring Forging | How to Produce a Seamless Rolled Ring

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.

Seamless Rolled Ring Forging | Solution to Achieving Structural Integrity

A seamless rolled ring forging is created through the process of ring rolling with the use of rolling mills. A circular preform of metal is pierced using the open die forging process to form a hollow shape that looks like a donut. Before placing the donut over the mandrel roll or the idler roll, the donut is heated above the recrystallization temperature. Once it is placed over the idler roll, the idler roll moves toward a continuously rotating drive roll to reduce the thickness of the ring’s walls while increasing its diameter. With the use of rolling mills that come in various sizes, seamless forged rings that have outside diameters that range from a few inches to more than 300 inches can be produced. It’s also possible to create forged rings that could weigh from a pound up to over 300,000 pounds.

Why Use Seamless Rolled Rings?

Casting and rolled and welded plates are both metalworking processes that allow you to produce rolled rings. Cast rings are prone to inclusion defects that need extra machining as well as weld repair. After the fabricated ring goes through extensive welding, the integrity of its part is reduced, its corrosion resistance is jeopardized, and its shape becomes distorted. On the other hand, with the forging process, the directional grain flow causes the forging’s overall strength to be increased. Plus, the maintenance of the part’s corrosion resistance and shape is ensured because of the absence of welding.
