[0001] The invention belongs to the technical field of single crystal blade casting applications, and in particular relates to a correction instrument for verticality positioning of single crystal blades. Background Art

[0002] In the conventional Bridgman process, the molded shells are arranged in a circle around a central rod and cast. To increase productivity, the aim is to produce as many blades as possible from one casting, which results in unfavorable thermal conditions.

[0003] The molded shell is heated externally mainly by direct radiation from the heater. The interior of the molded shell, which is oriented toward the central column, is subject to the so-called shadow effect and remains significantly colder than the outside. The isotherms or solidification fronts are not ideally horizontal but strongly curved. Contrary to the ideal state of one-dimensional temperature gradient (G) or heat flow (Q), it obtains a poor lateral component, which leads to poor arrangement of the dendrite structure and is conducive to the formation of terrible grain dislocations. Therefore, in order to ensure that the cast single crystal blades do not have the above problems, the manufactured mold shell needs to ensure good verticality (no tilt or tilt within the allowable error range).

[0004] Therefore, based on the above problems, the present invention provides a correction instrument for verticality positioning of single crystal blades. Summary of the invention

[0008] In the technical solution, the correction instrument for vertical positioning of single crystal blades also includes a circular positioning clamping hole arranged in one side of the disk and located at the symmetrical center of a plurality of limiting bosses.
