Rings are typically rolled by a process called ring rolling. Ring rolling is done on rolling mills. They can be produced in configurations ranging from flat, washer-like parts to tall, cylindrical shapes, with heights ranging from less than an inch to more than 9 feet. Let’s take a look at the process for rolled rings and how they are made.
Ring Rolling Process
Starting Stock – The first step is the rounding of the starting stock. It is then upset to achieve structural integrity and directional grain flow.
Punching and Piercing – After being rounded and upset, the stock is then punched and pierced to achieve the doughnut shape needed.
Idler Roll – After the stock has been given its doughnut shape, the rolling itself can begin. The process begins with the idler roll applying pressure to the preform against the drive roll.
Increasing Diameter – The next step is to increase the diameter. That happens as the continuous pressure reduces the wall thickness. The axial rolls then control the height of the ring as it is being rolled.
The Size is Achieved – This entire process is repeated until the desired size is achieved. At this point, the ring rolling process is complete and you have a rolled ring in your desired size and shape.
