Contoured rolled rings

Contoured rolled rings

Increased competitiveness

This ring forging process offers significant savings on material and machining hours, plus grain flow direction to the final shape. Contoured and near-net-shape rolled rings have both technical and economic benefits while meeting their unique geometries.

BENEFITS

• Near-net-shape rings bring significant cost savings on the input weight of raw material.
• Switching from castings to contoured rolled rings will result in an improved and consistently higher quality product.
• At FRISA, we have a vast experience producing contoured rings in any size and material grade and can recommend the best solution for you.

PROCESS

A seamless rolled ring is made in a three-step process, directing grain flow in tangential and radial directions to provide the pieces with strength, ductility, and resistance to impact and fatigue.

When it comes to rolled rings, basic shapes with rectangular cross-sections are the norm. However, we can forge more complex cross-sections by applying radial and axial pressure on the rolls of our ring mills.

We can meet virtually any design requirements with contours on the inside and/or outside diameter or even on the ring’s face.
