Unlike other types of ring forming, this forging process creates a seamless ring with great integral strength, capable of resisting high degrees of internal or external pressure. This is why wheel hubs, bearing housings, pressure vessels, gears, jet engine bearings, engine turbines and wind turbines - all applications which apply significant force - are usually made from seamless forged rings.

Seamless rolled rings are also utilized in nuclear reactors, off-road equipment, couplings, rotor spacers, sealed discs and cases, flanges, valve bodies and many other high stress applications.

A seamless rolled ring begins as a solid, circular block of metal that is heated to forging temperatures and then punched through the center to form a "donut" shape. This preform is then placed on a rolling rig with a roller touching the inside of the donut and a roller touching the outside of the donut. The two rollers begin to rotate in opposite directions, turning the ring, and at the same time the rollers slowly squeeze inwards, thinning the ring wall and causing the diameter of the ring to increase.

Some ring-rolling machines also have a roller that presses down on top of the ring as it turns, governing the height of the ring wall. The process continues until the ring has been thinned, flattened or otherwise shaped to its desired dimensions, at which point it may receive secondary processing such as size fine-tuning or heat treatment. Rings can be shaped at high forging temperatures for faster forging or, for rings that require the highest pressure resistance, such as aluminum car wheels, the rolling can be done at lower temperatures over a longer period.

Lower forging temperatures and longer forging times result in greater tensile strength. The ring-rolling process can be modified in any number of ways to produce a wide range of precise contours both on the inner dimension and outer dimension. Seamless rolled rings are unequaled in tangential strength, ductility, and adaptability.

Ring rolling mill is very important forging equipment for seamless rolled ring forging. When you decide to invest new ring rolling process line, it is essential to choose reliable ring rolling mill manufacturer.

Firstly, you must find trustworthy ring rolling manufacturer, not the trader or partner, only that, we can get first-hand price, immediate and direct service.

Secondly, you can&#;t judge from the appearance and design concept, since the principle of the ring rolling is almost the same. It is the same for other manufacturing equipment. You should judge from the core of ring rolling-how&#;s the quality of the forged rings after ring rolling, such as precision, ovality, allowance etc.

Thirdly, when you study the ring mill manufacturer, survey the rolling mill manufacturing experience and local market customers occupied, especially the repeated customers ordering. A trust and reliable manufacturer must have good reputation in local market. China is a large market for various products, if the manufacturer doesn&#;t have large portion market in domestic, it is not very reliable.
