5.2.3 The Ring Rolling Process | Forging Industry Association
Ring rolling is a hot forming process that produces seamless rings varying in size from a few inches in diameter, and weighing less than one pound, to over 25 feet in diameter and face heights approaching 10 feet. The process and equipment are similar in principle to rolling mills used for plate. In both processes, the metal is rolled between two rolls, which move toward each other to form a ...
Steel Rolling :: Total Materia Article
The principal criticism of the traditional mill is this tendency for roll bending due to its inherent design - the beam principle. Sendzimir proposed a design which eliminated this limitation based on the castor principle where the work roll is supported over ali its face by an array of backing rolls.
Practical Roll Techniques - Grinding & Balancing
This paper provides practical tips on roll inspections, balancing, grinding and grooving. In addition, we discuss proper roll handling during removal, storage, transport, and reinstallation. Finally, ceramic roll conditioning is discussed. It allows for returning the roll to its original finish while the roll is still in the machine.
Roll Forming Design Guide for Sheet Metal Components
In the roll forming process, a strip of metal is fed through a series of mated roll dies that are installed onto the shafts of a mill's forming stands. If the component being produced requires additional features (holes, slots, cut outs, tabs, etc.), your manufacturer needs a punch press, or other equipment.

Shoulder alignment, spaces and roll design should all be carefully. scrutinized to minimize sweep issues. 4. Edge wave. Edge waves easily happen in the roll-forming process of thin steel parts, which greatly influences the forming quality. Waves can occur because the distance from the edge to the first bend is too great, or the metal is too thin.
