초록 ▼

Disclosed is a single-cast, thin wall structure capable of withstanding impinging gases at temperatures of 4300°F. and higher, and method of making the same. Using a bleed line of the instant invention allows for a decreasing metal pressure with respect to time which prevents any damage to the thin

대표청구항 ▼

A process of casting a molten alloy into a mold cavity having a thickness of less than about 0.03 inches, defined at least partially by a ceramic shell, so that said shell is not substantially distorted and said mold cavity is not substantially expanded during the casting step comprising; charging molten alloy into a mold reservoir which communicates with a charge line and a mold cavity defined by a ceramic shell and having a thickness less than about 0.03 inches, wherein the amount of molten alloy charged into the reservoir is sufficient for the molten alloy to flow by gravity from the reservoir through the charge line and to completely fill the mold cavity having a thickness less than about 0.03 inches; bleeding off molten alloy at a location above the mold cavity having a thickness less than about 0.03 inches so that the alloy pressure in the mold cavity is decreased over time and so that the ceramic shell is not substantially distorted and the mold cavity is not substantially expanded during the casting process; and solidifying the molten alloy to produce a solid metal part having a portion with a thickness less than about 0.03 inches corresponding to the mold cavity.
