ABSTRACT:
A method and apparatus for horizontal continuous casting of metal alloys, such as brass, which tend to have a component thereof separate therefrom, in vapor form, during and immediately after solidification of the metal. The molten metal alloy progresses from the entrance end toward the discharge end of a horizontal tubular mold, with the metal solidifying at least next to the inner surface of the mold before reaching the discharge end thereof. The solidified metal in the mold shrinks inwardly away from the mold surface to form a shrinkage gap therewith, so that the above component of the alloy in vapor form enters into this shrinkage gap. In accordance with the invention this shrinkage gap is maintained filled with a gas which is inert to the above vapor so that the latter cannot oxidize in the shrinkage gap. In this way it is possible to avoid formation of undesirable deposits at the inner surface of the mold.
