ABSTRACT:
A method and apparatus for the lost pattern casting of metals is disclosed. In the method, a pattern is formed from a material and a mold is formed around at least a portion of the pattern. The mold includes a particulate material and a binder. The pattern is removed from the mold and molten metal is delivered into the mold. The mold is contacted with the solvent and the molten metal is cooled such that it at least partially solidifies to form a casting. The step of cooling includes contacting a shell of solidifying metal around the molten metal with the solvent. An apparatus is also disclosed.
