Heating the Billet:

The process begins by heating a metal billet to a temperature that makes it pliable. This is typically done in a furnace. The choice of metal can vary, with common options being steel, aluminum, and other alloys.

Creating the Preform:

Once the billet is heated, it is punched in the center to create a hollow ring-like shape, also known as a preform. This initial shape is crucial for the subsequent rolling and forging steps.

Ring Rolling:

The preform is then placed in a ring rolling machine. This machine uses rollers to expand and shape the preform into a seamless ring. The process involves two main rollers: the driven roll and the idle roll. As the driven roll pushes against the idle roll, the ring expands and takes on its final dimensions. This rolling process ensures that the ring is evenly shaped and free from defects.

Forging the Ring:

After rolling, the ring may undergo additional forging to refine its shape and improve its mechanical properties. This can include processes like quenching and tempering, which enhance the ring’s strength and durability.

Final Inspection:

The final step involves inspecting the seamless rolled rings for any imperfections or inconsistencies. This ensures that each ring meets the stringent quality standards required for its intended application.
