CERAMIC MOLD FOR CASTING ARTICLES WITH ORIENTED AND MONOCRYSTALLINE STRUCTURE Russian patent published in 2003 - IPC

Abstract RU 2201843 C2

FIELD: foundry, possibly casting of articles used, mainly as blades of gas turbine engines and gas turbine plants. SUBSTANCE: ceramic mold has pouring cup, casting cavity, working cavity and starting cavity. In lower portion of starting cavity at least one heat conductive member is placed. Said member protrudes outside mold and it is made of material with high thermal conductivity. At immersing into metallic bath, heat conductive members are intensively cooled causing occurrence of large number of fine equiaxial grains in casting alloy. Oriented and monocrystalline structure is formed due to high axial heat removal in article. EFFECT: possibility for making cast article with optimal set of properties. 6 cl, 2 dwg
