ABSTRACT:
A charge of melt in an amount sufficient to cast only one mold is admitted to a casting basin from a melt-holding chamber. A casting mold is immersed in the freshly admitted charge and the charge is countergravity cast into the mold by establishing a suitable differential pressure between the mold and the charge. After casting, insufficient charge is left in the casting basin to cast the next mold whereupon the casting basin is supplied with the next fresh charge of the melt for casting the next mold. In this way, a fresh charge of melt is cast into each mold in a series of molds. Each charge of melt may be treated (e.g. nodularized) in-situ in the casting basin such that each mold is filled with a freshly treated (nodularized) charge of melt having an effective concentration of the alloyant therein.
