Forged Steel Rings Specification


Key componentNonmagnetic retaining ring is a critical component of heavy turbonator, one of the components bearing the highest stress, and by means of the retaining ring the centrifugal force is borne on the location of turning of the coil block on the both ends of the rotor.
CharacteristicsThe retaining ring is hot assembled on the both ends of the rotors to compact the coils on the ends to prevent the coils of rotors during high speed operation from runaway damages which might cause disastrous accidents to the power stations
GradesUnique heavy retaining ring presses are available in China and by them all the retaining rings with the specifications such as 3 MW – 1,000 MW grades are able to be manufactured.
