During the ring rolling process, temperature losses can be counteracted with an induction heating system.
On a radial-axial ring rolling machine, a pierced piece of basic material (blank) is formed to a seamlessly rolled ring in a continuous rolling operation. The cross-section of the ring is reduced in its wall thickness and height. Consequently, the diameter is enlarged. The driven main roll and the mandrel from the radial roll pass, thereby reducing the wall thickness.
Both driven axial rolls – the axial roll pass – serve to reduce the ring height. During the rolling process, a ring centering device retains the rotating ring in a defined position. Rings with rectangular cross-section and profiled rings can be rolled for different applications. Depending on the application of the finished product, most varied materials are rolled on the ring rolling machines. This encompasses all common steel grades as well as titanium and nickel-base alloys, copper and aluminium alloys, etc.
