Definitions

  • the invention relates to a process for the production of refractory ceramics for use as a heat shield in the hot gas path of gas turbine plants according to the preamble of claim 1.
  • Gas turbine plants essentially consist of a compressor, a burner and an expansion turbine.
  • In the compressor intake air is compressed before it is mixed in the nachge ⁇ off and disposed in the compressor plenum burner in a combustion chamber with fuel and burned this mixture.
  • the downstream of the combustion chamber for drinks ⁇ cycle turbine then withdraws the resulting Verbrennungsabga ⁇ sen thermal energy and converts it into mechanical energy ⁇ Ener.
  • a generator connected to the expansion turbine converts this mechanical energy for generating electricity into electrical energy.
  • Such heat shields can be carried out both metallic and ceramic.
  • ceramic materials vorzugt loading that are provided ⁇ for example by a casting process ago.
  • air pockets can form in the casting compound, which lead to defects (blowholes) in the green body or in the finished component can. These defects are present both in volume and on the surface of the refractory ceramics.
  • surface defects are the main criterion for quality control in the context of quality control, as these particularly affect the mechanical properties. Due to the voids, it can lead to a weakening of the mechanical structures and thus to increased cracking in the refractory ceramic.
  • the object of the invention is to provide a method to stel ⁇ len, which avoids this disadvantage.
  • a heat shield consisting of at least one refractory ceramic manufactured by the method according to the invention is particularly robust and a gas turbine plant equipped with such a heat shield can be safely operated.
  • the invention will now be explained by way of example with reference to the refractory ceramic K shown in the figure.
  • a non-nä ⁇ forth shown mold cover is used, which dips when placed on the mold shell in the molding compound therein and the casting compound when closing the lid zuneh ⁇ ing up to the mold closure with a previously defined static Pressure applied.
  • the filling level of the casting compound represents the essential process parameter, which determines the mass displacement degree and thus the resulting static pressure.
  • the placing of the mold cover can already be carried out with vibration.
  • For secure mold closure is the
  • a clamping device with the high clamping forces can be generated.
  • a clamping ⁇ device represent, for example, toggle clamps.
  • the geometry of the mold closure already corresponds to the actual geometry of the produced refractory ceramic K, so that a reworking of the component surfaces can be completely eliminated and also the grinding of any existing sprue webs can be significantly reduced.
  • the sealed, static pressure mold is then vibrated directionally. With the vibration ⁇ or force introduction direction V, which is determined by the position of the mold relative to the vibration direction, the distribution of surface and volume errors (voids) in the component K can be controlled.
  • the force direction V is to be chosen such that it toward the Oberflä ⁇ normals N of the quality-critical component area - acts - here the hot gas side HS of refractory ceramics.
  • a virtually void-free surface of the hot gas side HS of the refractory ceramic for gas turbine plants can be achieved.
  • the side surfaces SF - similar quality requirements as the hot gas side described above are subjected to HS, the directed Vib ⁇ ration for these areas is to be repeated in the same manner.
  • the casting mold is then vibrated one after the other in a direction normal to the quality-critical component surfaces.
  • the essential process parameters for the directed vibration make the vibration direction, time, frequency and - amplitude and the stati ⁇ specific pressure generated by the mold closure is Overall, there are therefore by the inventions dung process according to the following advantages:.

Abstract

L'invention concerne un procédé de fabrication de céramiques réfractaires (K) destinées à être utilisées comme bouclier thermique dans le trajet de gaz chaud d'installations de turbine à gaz. Ledit procédé comprend les étapes consistant à verser une matière de coulée dans un moule de coulée de pièce pour la céramique réfractaire (K), à fermer le moule de coulée, de sorte que la matière de coulée se trouve sous une pression statique définie après la fermeture, à amener le moule de coulée à vibrer de manière orientée dans la direction (V) d'une normale (N) à une surface de la céramique réfractaire (K) à fabriquer, pour laquelle des exigences de qualité particulières sont exigées lorsqu'elle est utilisée comme bouclier thermique, puis à démouler et à cuire la pièce coulée.
