ABSTRACT:
A method for melting and casting of metals and alloys and an apparatus using the method. The method consists of utilizing a compact assembly for melting and centrifugal casting of metals. The assembly includes a mold or chiller which is rotatable around a vertical axis. The mold communicates with a sealed lower housing containing an oven for the melting of the metal. The assembly is such that the interior chambers of both the oven and the mold are positioned in a vacuum during the entire time of the process of melting of the metal contained in the oven. The oven is movable vertically and is maintained in a position such that the lower extremity of a hollow vertical channel which feeds the mold, remains outside of the molten metal in the interior cavity of the oven when melting is occurring. Thus, the melting is accomplished entirely in a vacuum condition, thereby avoiding the formation of oxides or other chemical compounds.
