ABSTRACT:
A metallurgically improved metal casting (10) is made with increased productivity, wherein molten metal is quiescently fed upwards into a molding chamber (14) which is then inverted. An assembly of refractory cores (12) is used that defines the molding chamber (14) with riser channels (16). A metal entrance (18) to the molding chamber (14) through a mold side wall (20) requires feeding molten metal against gravity to fill the molding chamber (14), and quiescently pressure feeding molten metal through a metal launder (26) to fill the molding chamber (14) and the riser channels (16). A mold
ozzle connection between the metal launder (26) and the source of molten metal delivered under pressure is rotationally flexible and axially compliant. The feeding of molten metal is interrupted and the assembly is rotated about an axis passing through the mold
ozzle connection (28) to invert the assembly while maintaining the mold
ozzle connection. The mold
ozzle connection (28) is then severed from the inverted assembly. Molten metal is then allowed to feed under gravity into the molding chamber (14) from the riser channels 16 and the metal launder (26) is drained. Meanwhile, the molding chamber (14) is removed from the mold
ozzle connection (28), and a subsequent mold is filled.
