Custom Seamless Rolled Ring Forging

The seamless rolled ring forging process combines strength, toughness, and fatigue resistance through a unique grain flow.

The process begins with cutting the initial material stock to size and then rounding it using open die presses. This rounded piece is subsequently upset and pierced to create a preform, essentially a rolled ring forging ready for the ring rolling mill. On the rolling mill, axial rolls control the ring's height, while an idler roll applies pressure against a drive roll. These forces reduce the wall thickness and height of the rolled ring while increasing its diameter until the desired size is achieved. At Runchi, we forge seamless rolled rings in a wide range of sizes and grades, including carbon and alloy steels, stainless steels, and custom-specific grades.

Advantages of Custom Seamless Rolled Ring Forging:

When it comes to obtaining metal rings for various applications, the choice of the metal forming process is crucial. Cast rings often suffer from poor strength and integrity, while rings cut from plate materials and welded together can be susceptible to fatigue, excessive material, and processing costs. Custom forging, as performed by Runchi experts, offers greater versatility and improved quality while reducing material expenses. Additional benefits include:

Controlled directional grain flow
Increased strength
Enhanced structural integrity
Elimination of inclusions and porosity
Minimized waste
Elimination of welding, reducing the risk of part fatigue and breakage
