STEAM TURBINE SEAL RING FINISHING APPARATUS AND METHOD OF USE

原文（中国語）

A finishing apparatus enables an outer diameter of a seal ring to be reduced. The finishing apparatus includes a first plate including a first peripheral angled surface, and a second plate including a second peripheral angled surface. The second peripheral angled surface is spaced a distance from the first peripheral angled surface when the finishing apparatus is assembled. The first and second peripheral angled surfaces define at least a portion of a wedge-shaped receiving cavity that is shaped complementary to a shape of an inner diameter of the seal ring to facilitate securing the seal ring in position relative to the finishing apparatus while the outer diameter of the seal ring is finished to a pre-determined size.
