ABSTRACT:
Method and apparatus for continuously casting hollow bars in which a one-piece mandrel is suspended from a support bar secured across the top of a female die by a retaining ring which holds down the female die. A cooler surrounds the female die and the retaining ring is fixed to the cooler. The mandrel extends axially within the female die, and the mandrel support bar leaves relatively large crescent-shaped pouring areas permitting easy access by a pouring spout which dispenses molten metal directly into the space between the female die and the mandrel. Quick connect and disconnect fasteners are employed to secure the support bar to the retaining ring so as to facilitate replacement of the mandrel during a casting operation. A pair of guide pins is also provided to facilitate and center installation of the mandrel.
