What is Seamless Rolled Ring Forging & What are Rolled Rings Used for?



Forging is the process through which stronger machinery components are produced. For example, when components are needed for wind turbines to be developed or gears of high quality need to be developed for mechanical parts, the seamless rolled ring forging process is what is used for the development of these pieces

Seamless Rolled Rings

These are rings that are produced through a process known as ring rolling. This process uses a machine known as a rolling mill. The rolling mill can be used to create rings that vary in diameter and weight.

The rolled ring creation process begins when you cut the starting stock of your desired material to the right size. This process has to take place before you round it on the presses of an open die. The piece that is now round is then upset and then pierced to turn it into a preform. This preform serves to form a component that is shaped like a doughnut that is now ready to be placed on the rolling mill.

The rolling mill is made up of axial rolls whose purpose is to control the height of the ring and also an idler roll whose main purpose is to ensure that pressure is applied onto the ring as against a drive roll.

The pressure that is being generated by these forces known as ID and OD pressures causes the wall thickness to decrease and the height of the rolled ring to increase, this continues until the desired size is achieved

The seamless rolled rings attain their definitive shape through the use of a shaping tool. By using this tool, the shape or size of the rings can be achieved

Seamless rolled rings are produced by the use of different configurations such as tall cylinders and smaller parts resembling washers

What Are Rolled Rings Used For?

Forged-rolled rings are used in the aerospace industry
When it comes to the aerospace environment seamless rolled rings play a vital part in producing key components parts such as jet engines and turbines.

Forged rings, seamless rings, and discs assist in the powering of jet engines. It also comes in handy in the assembling of a helicopter rotor and gearboxes. The rings also provide a much greater strength as opposed to weldments, castings, or even flame –cute plates hence emerge as a much better fit for aerospace companies.

Forged Rolled Rings

Automotive and Truck Industry
Due to the characteristics of forged rings such as strength, durability, and reliability; forged parts are vital in the automotive and truck industry.

They are ideal for use in points associated with shock and stress such as wheel spindles, axle beams, kingpins and shafts, idler arms, torsion bars, and steering arms.

They are also found in the power train where rods that connect, transmission shafts and gears, clutch hubs, and universal joints are often created.

Although they are mostly created from carbon or alloy steel, other materials that can also be used to develop rolled forged rings such as aluminum and micro-alloyed steel are also starting to make their way into truck applications.

Forging has been associated with the mark of quality in hand and hardware tools.  For example, pliers, sledges, gardening tools, sockets, wire-rope clips, hooks, and eyebolts are just some examples of where forged components apply. Dental and surgical instruments are more often than not forged.

Hardware created especially for electrical transmission and distribution such as sockets, brackets, and suspension clamps is known to be commonly forged for dependability, resistance to corrosion, and strength.

General Equipment
Forgings that are often of great size are mostly associated with equipment found in industries such as textile, paper, power generation, and transmission, steel to mention just but a few.

Configurations in these industries include but are not limited to bars, cylinders, elbows, rings, connecting rods, sleeves, shafts, and blocks

Shipbuilding and Defense
It is difficult not to find forged components in every implement of defense be it from rifle triggers to nuclear submarine drive shafts, missiles, and heavy tanks, shells, armored personnel carriers. All these pieces contain a certain degree of forged components.

Oil Field Applications
Due to their freedom from porosity and their exhibit of great mechanical properties forged components are usually associated with a high tolerance for pressure in the valve and fitting industry.

Due to their immunity to corrosion and heat resistance, forged components are used for flanges, valve bodies’ saddles, and stems. In the oil industry, they are used for drilling hardware and as rock cutter bits and in high-pressure valves and fittings.
