Ring rolling is an advanced and versatile operation. The primary applications of this work are for the production of anti-friction bearing races and railway wheels. You can also use it for a myriad of ring shape components for the aerospace and automotive industries. The components here include aluminium rolled rings.
How does ring rolling work?
Rolling is the continuous forming of metal between a set of rotating rolls. The height and shape of said rolls is incrementally lowered to generate the desired section. This happens through imposing high pressures to achieve plastic deformation. It lowers the thickness and increases the length without markedly increasing the width.
With the ring rolling process, you can do it with the material at a high temperature. Or, it can be at an ambient temperature initially. It depends on the specific material and its characteristics; some materials are hard and durable so you need to heat them to increase malleability.
Ring rolling is a fantastic practice. It allows easy manufacturing of seamless rings with flexible cross-sectional shapes. There is also minimal scrap and improved grain structure. If you need 5083 (H111) aluminium rolled rings, talk to our team.
The process and equipment used aren’t unlike rolling mills for plate production in principle. With both operations, you roll the metal between rolls. Said rolls move towards one another to create a continuously reducing gap. With ring rolling, the rolls are of separate geometries and diameters.
What can you make with this process?
Ring rolling comes into play when people make anti-friction bearing races and railway wheels. Another use is for different ring shaped work pieces for aerospace and automotive projects. The rings here can vary in size to suit various needs; typically it just requires simple set up changes.
Furthermore, the ring rolling operation is extensively used to create seamless rings. It does this by performing a continuous, albeit gradual, procedure. There are many outer ring diameters for power generation, large cylindrical vessels, and aircraft engines.
Ring rolling’s advantages include uniform quality, close tolerances, and short production times. You can make considerable savings on material costs too.
Furthermore, the primary benefit of the work pieces created here is provided by the orientation and size of grains. This is especially true with the exterior. It offers the final product fantastic mechanical features. Speak to us if you want excellent 5083 (H111) aluminium rolled rings.
Benefits of the ring rolling work if you compare to the ring forging procedure include a faster working time. The grain flow forms continuously here too, something that is favourable by nature.
Production steps
Next, we will discuss the main production steps of the ring rolling operation. It starts with a forged bar that you upset and pierce to gain a hollow circular preform. You put the preform over the idle roll that’s faced towards the driven roll. At the same time, the axial rolls apply pressure in a direction that is parallel to the ring axis. The idle roll is able to lower the width while the axial rolls minimise the height of your ring’s cross section.
The axial rolls and coupled with the idle’s movement imparts the desired shape to the cross section. This increases the ring diameter. The starting section of the work piece could have a complex or rectangular shape. Thanks to the operation’s nature, you use separate rolling mills, such as driven roll, idle and axial roll.
