ABSTRACT:
As a reversal of previous practice, the annular body of the mold in the unit has an annular case at the bottom thereof, rather than at the top thereof. The case is relatively thick axially of the mold, so as to form the greater portion of the axial length of the mold body at the outer periphery thereof; and at the top thereof, the case has an annular plate thereon, which forms a pair of flanges that overhang the case and enable the metal casting unit to be lowered into an aperture of a casting table from above, and supported on top of the table at the flanges. Meanwhile, the case defines the lower end opening of the mold cavity, and the outlet for liquid coolant that is discharged onto the molten metal body as it emerges from the unit. Commonly, the case is monolithic, and also has an annular sump at the top thereof which is covered by the plate to form a chamber for the coolant in the sump. A graphite casting ring may be circumposed about the inner periphery of the case, to form a liner for the upper end portion of the cavity; and a refractory top ring may be circumposed about the upper end opening of the cavity, to form a hot top for the ring.
