Abstract
PURPOSE: To suppress a generation of defective casting, and heighten a precision of arrangement position of the nozzle blade and an easiness of surface processing work, by casting a leg part, protruding from the blade plate for wrappage casting, in outer ring and separator plate, and manufacturing a stationary blade disc of the turbine.
CONSTITUTION: An outer ring 20 and a separator plate 10 are separately made respectively, and a mold, with an independent pouring gate provided, is prepared. A nozzle blade 30, made in a completion of manufacturing work as an independent part so as to extend over each mold, is circumferentially arranged and fixed and supported in a prescribed position. Under this condition, a leg part 32, for wrappage casting, of T-letter shape or double tail shape, is being inserted and positioned into within each mold. With a pouring performed, the leg part 32, in the condensing process of molten metal, is deposited by a wrappage casting in the outer ring 20 and the separator plate 10, and the stationary blade nozzle disc is cast and constructed.
