摘要:One end opening of an open ended mold cavity has a diameter smaller than the peripheral wall of the cavity and a molten metal mass is introduced to the cavity by continuously filling the one end opening with the mass so that the molten metal splays about the inner peripheral edge of the opening to assume a cross-ction between the ends of the cavity having a divergent/convergent outline, the intermediate continuum of which between the planes of maximum divergence and minimum convergence thereof, has a peripheral outline corresponding generally to the outline of the cavity at the peripheral wall thereof. A graphite or graphite-like ring is circumpod about the axis of the cavity in the peripheral wall thereof to form a solid but fluid permeable wall ction that is dispod to define the peripheral outline of the intermediate continuum of the metallic mass. A lubricating oil and a gas are delivered to grooves on the outer peripheral portion of the ring, and are caud to diffu simultaneously through the body of the ring so as to discharge into the cavity at the inner peripheral surface of the ring while the molten metal mass is chilled and the mold and a support are reciprocated in relation to one another axially of the cavity to form the chilled mass into an elongated
body of the metal.
