Basics of Classic Rolled Ring Technique

Do you ever wonder how the procedure of creating rolled rings work and the techniques used for producing bearing rings? The process begins with the piercing of a circular preform of metal so as to produce a ring-like structure. As soon as this is formed, the ring is rotated and heated until its desired wall diameter and thickness are achieved.

Hot Radial Rolled Ring

This advanced and innovative rolled ring technique is normally used for manufacturing medium-scale bearing ring under high temperature via the hot radial rolled ring (HRRR) mill. During the rolling process, the HRRR mill’s main roll part makes the active rotation as well as the linear feed while its mandrel part creates a passive rotation.

Its guide roll’s placement is fixed at the main roll’s exit side while the signal roll can be found at the opposite side of the guide roll. The ring rolling process ends when the ring’s diameter touches the guide roll. Techniques when it comes to rolled rings are challenging; thus, it is essential that you know which technique to use and how it specifically works in order to prevent any sub-standard or low-quality products.

Cold Rolled Ring

This classic technique of producing quality rolled rings is considered as an advanced rotary forming technique that’s created to manufacture seamless rolled ring forgings in a high-temperature room through a cold-rolled ring mill. The main CRR mill has a mandrel part that makes linear feed, the main roll part that creates active rotation, a measured roll that measures the ring’s diameter, a guide roll that moves according to ring’s expansion, a frame part, and a power and control system.

During this process, a blank or a pre-turned ring is rolled between two rolls that may have specific profiles or may have no shape. The rolling process ends when the ring’s diameter meets the target value.

Benefits of Using Forged Rolled Rings

The forged rolled rings process begins with a heated circular mass of metal that is ready to be molded after being formed and pierced to form a hollow “doughnut”. This is then heated to a high temperature and placed over the mandrel roll.

The roller then moves under extreme pressure towards the constantly rotating drive roll that reduces the thickness, increasing the diameter of the final product. It can produce everything from flat washers to tall cylindrical parts.

Process and Benefits of Forged Rolled Rings

What is the Process?

When it comes to the rolled rings process, it can be broken down into six steps. In the first step, the billet is cut to the proper size and is then upset to achieve the right properties. After that, the center is punched to create the ring that is rolled.

After the donut is ready for ring rolling, the ring is placed on an idler roll and is manipulated by axial rolls and the drive roll. The ring diameter slowly increases as more pressure is applied and once the desired size is reached, the process is done.

Benefits of Forged Rolled Rings

When it comes to this kind of forging, there are a lot of benefits. Given the rolled rings process, one of the biggest benefits is how strong the final product is. Any material that is forgeable can be used to make rolled rings.
