ABSTRACT:
A method and apparatus for melting and fine-casting precious metals in which a closed, gas-pressurizable crucible is arranged on top of a molding cell and connected thereto via a valve-controlled tapping passage. The melt is tapped under pressure into an evacuated mold, thereby inhibiting melt evaporation and improving melt flow into the mold branches.
