ABSTRACT:
This invention relates to an improved self-centering bottom block assembly for D.C. casting. The assembly comprises a bottom block which is slidably mounted on a supporting surface and which is provided with at least two guide extensions. Positioned below the D.C. mold are at least two recessed guide surfaces, the lower portion of which converges in the direction of the discharge end of the mold. The horizontal and rotational movement of the bottom block is restricted so as to ensure the insertion of the guide extensions into the recess defined by the guide surfaces and thereby guide the bottom block into the mold bore without contacting the mold body.
