ABSTRACT:
Manufacture of a turbine diaphragm assembly is effected by forming an arcuate V-shaped nozzle block mounting groove on the front side of a generally cylindrical plate so that the respective side surfaces of the V-shaped nozzle block mounting groove has a predetermined slope with respect to the longitudinal axis of the cylindrical plate, investment casting a plurality of individual nozzle blocks each of which includes, a nozzle blade extending in curvilinear fashion between an inner and an outer shroud segment which shroud segment on each nozzle block interfits with the inner and outer shroud segment of each of the other nozzle blocks, the said inner and outer shroud segments being sloped on their outer surfaces to correspond with the slope of the respective inner and outer side surfaces of the V-shaped nozzle block mounting groove so that an arcuate array of said nozzle blocks can be mounted in said V-shaped nozzle block mounting groove in interfitted, side by side relationship in such a manner that the respective exit edges of the respective nozzle blades of said nozzle blocks are substantially radially disposed relative to the longitudinal axis of said cylindrical plate, bonding said inner and outer shroud segments of the respective plurality of nozzle blocks to the respective inner and outer side surfaces of said V-shaped nozzle mounting groove, and removing material from the back face of said cylindrical plate in alignment with said nozzle blade mounting groove so as to open flow passages through said cylindrical plate as defined by the adjacent nozzle blades of the interfitted nozzle blocks.
