Raw rings

Our seamlessly rolled rings are manufactured in the most modern ring-rolling mills by our companies in Germany, the USA and China. With a manufacturing area with a 300 to 8,000 mm outer diameter, we are able to offer our customers a wide range of seamlessly rolled rings. CNC ring-rolling programmes in manufacturing enable optimal quality and reproducibility.

rothe erde® impress with their performance, which they owe to the seamless rolling process. Warm treatment generates the many mechanical properties demanded of the rings. Besides the normalising, the tempering and soft annealing of the rings enables programmed processes for all (special) materials to comply with the specific time-temperature provisions most accurately.
