Manufacturing of automated complexes for production of GTE cast intricate-shaped parts with directional and single-crystal structures

Manufacturing of automated complexes for production of GTE cast intricate-shaped parts with directional and single-crystal structures

For realization of promising technological processes VIAM has developed and manufactures vacuum melting-pouring units with principally new thermal assemblies meeting the requirements of modern technological processes and equipped with automated computer control systems.

Units for high-gradient directional solidification provide:

  • cooling efficiency of castings is 2.5-5 times higher than that implemented in foreign units by Bridgemen method;
  • obtaining of homogeneous fine-dendritic structure in castings;
  • 10-20% increase of strength and fatigue characteristics of alloys;
  • increase of yield in terms of blades macrostructure.

The following units are applied for serial production of blades with directional and single-crystal structures under condition of temperature gradient G ? 100 degree/cm: UVNK-9A – for blade casting up to 300 mm;
