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-section 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 circumposed about the axis of the cavity in the peripheral wall thereof to form a solid but fluid permeable wall section that is disposed 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 caused to diffuse 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.

摘要： One or more top-opening mold cavity defining members are supported in the chamber of a coolant box adapted for the flow of liquid coolant therethrough about the members. Each member is supported in a telescoping assembly in which the top opening of the member is co-axial with an opening in the top of the chamber to enable molten metal to be introduced to the cavity of the member through the respective top openings of the chamber and the member. Moreover, each member has a greater outer peripheral diameter transverse the axis than the top opening of the chamber, and is engaged with the top of the chamber about the opening thereof in a first horizontal plane of the box. The member is also engaged with the defining surfaces of the chamber in a second horizontal plane of the box spaced below the aforesaid first horizontal plane of the box by a vertical gap. Should liquid coolant leak into the gap through this second line of engagement, it is discharged from the gap at a level below the first horizontal plane of the box, and to a point outside of the chamber at which the leakage cannot reach the cavity of the member along the first mentioned line of engagement at the top of the chamber. As a result, the top opening of the chamber need only be large enough to enable the metal to be charged through the same, and the number of openings in the top of the chamber can be increased and/or spaced more closely to one another to maximize the number of molding stations in the device.
