Abstract: Molten metal is injected uniformly into a horizontal mold from a feed chamber in a horizontal direction at a controlled rate, directly on top of the metal already within the mold. A cooling medium is applied to the bottom surface of the mold, with the type and flow rate of the cooling medium being varied to produce a controlled cooling rate throughout the casting process. The rate of introduction of molten metal and the flow rate of the flow rate of the cooling medium are both controlled to produce a relatively uniform solidification rate within the mold, thereby producing a uniform microstructure throughout the casing, and low stresses throughout the casting.

Abstract: A baffle includes a base and a seal having flexible segments which engage a mold structure. The base of the baffle may have a noncircular opening in which article mold portions of the mold structure are disposed. The baffle may be connected with the furnace assembly before a mold is moved into the furnace assembly or may be connected with the furnace assembly as the mold is moved into the furnace assembly. A projection connected with the mold structure may be utilized to orient the baffle relative to the mold structure. The projection may be a thermocouple assembly which extends from the chill plate. Alternatively, the projection may be a portion of the mold structure itself.
