  • Iron alloy casting method and apparatus
    Patent number: 6554050
    Abstract: Irregularly shaped mold-core assemblies are retained for casting within a thin-wall container by solid particulate material. In the process, the mold and core elements are formed from the core sand. After the mold and core elements, both of which are formed from core sand, are assembled, the assembly is placed in a container large enough to provide space around the assembled mold and core elements, and solid particulate material is placed in the space around the mold-core assembly to hold the assembled mold and core elements together during pouring of the molten iron alloy into the mold-core assembly and the cooling period, during which the molten iron alloy solidifies to form the casting. After the casting is formed, the solid particles and the core sand from the mold elements and core elements are recovered, processed and reused in further casting operations.
