PROCESS FOR PRODUCING REFRACTORY CERAMICS FOR GAS TURBINE PLANTS

摘要

A process for producing refractory ceramics (K) for use as heat shield in the hot gas path of gas turbine plants: introducing a casting composition into a component casing mold for the refractory ceramic (K), closing the casting mold so that the casting composition is under a defined static pressure after closure; orienting vibration of the casting mold in the direction (V) of a normal (N) to a surface of the refractory ceramic (K) to be produced, and subsequently removing the casting from the mold and firing the cast component.

1. A process for producing refractory ceramics for use as a heat shield in the hot gas path of gas turbine plants, comprising the steps of:
filling a component casting mold for the refractory ceramic with a casting composition; closing the casting mold, so that the casting composition is under a defined static pressure after closing; and directionally vibrating the closed casting mold in a direction (V) of a normal (N) to a surface of the refractory ceramic to be produced in the mold so that the ceramic component meets particular quality requirements for use as a heat shield; and subsequently demolding and then firing of the cast component.
