摘要： An improved mold has a coating of material having a relatively high emissivity. The surface of the coating has an emissivity which is at least twice as great as the emissivity of the surface of the ceramic mold material. When the mold is removed from a furnace chamber, the surface of the coating radiates heat at a relatively high rate. In one embodiment of the invention, the coating is applied to only a portion of the surface of a ceramic mold. In another embodiment of the invention, the coating of material having a relatively high emissivity is applied to only a portion of a crystal selector on a mold for a single crystal article. The relatively high rate of radiation of heat from the coated portion of the crystal selector increases the rate of growth of an adjacent single crystal grain. If desired, the entire mold can be covered with the coating of material having a relatively high emissivity. The coating of material having a high emissivity may be formed of graphite.
摘要翻译：改进的模具具有具有较高发射率的材料涂层。涂层表面的发射率至少是陶瓷模具材料表面发射率的两倍。当模具从炉室中取出时，涂层的表面以相对高的速率辐射热量。在本发明的一个实施例中，涂层仅施加到陶瓷模具的表面的一部分上。在本发明的另一实施例中，具有较高发射率的材料涂层仅施加于单晶制品用模具上的晶体选择器的一部分。来自晶体选择器的涂覆部分的相对较高的热辐射率增加了相邻单晶粒的生长速率。如果需要，整个模具可以被具有较高发射率的材料涂层覆盖。具有高发射率的材料的涂层可以由石墨形成。

摘要： An improved apparatus and method is used to cast a plurality of articles in a mold structure having a plurality of article molds disposed in an array having an open central portion. The article molds are filled with molten metal while the mold structure is supported on a chill plate. An inner baffle plate is disposed in the central portion of the array of article molds and retards the transfer of heat from the article molds to the chill plate. The inner baffle plate is supported by a support structure which extends through the chill plate. After the article molds have been filled with molten metal, the chill plate and mold structure are lowered relative to the inner baffle plate to increase the rate of heat transfer from the article molds to the chill plate through the open central portion of the array of article molds. Thereafter, the inner baffle plate and support structure are lowered with the chill plate and mold structure. An outer baffle plate extends around the outside of the mold structure and is supported by the support structure. The outer baffle plate may be pressed against the bottom of a furnace to retard heat transfer between the inside and outside of the furnace along a path extending outside of the mold structure.

摘要： To inspect recesses in sides of an airfoil, gauge heads are moved into engagement with the recesses. Fluid pressure is conducted to the recesses while the gauge heads are in engagement with the recesses. A determination is made as to whether the rate of leakage of fluid from the recesses is greater than or less than a predetermined rate. If the rate of leakage of fluid is greater than a predetermined rate, one or more of the recesses is unacceptable. However, if the rate of leakage of fluid pressure is less than the predetermined rate, the recesses are acceptable.

摘要： A method of forming a pattern includes providing an actual core having dimensions which are different from dimensions of an ideal core. A best fit spatial relationship of the actual core to a spatial envelope for an ideal core is determined. Locating surfaces in a die are moved to positions, at least some of which are offset from ideal core locating positions, in which the actual core is positioned in a best fit spatial relationship with the spatial envelope for the ideal core. A plurality of motors may be utilized to move the core locating surfaces to desired locating positions. The actual core is positioned in engagement with the core locating surfaces and a flow of wax is conducted into the die. If desired, a best fit spatial relationship of the actual core to a die cavity may be determined, rather than a best fit with an ideal core.

摘要： An apparatus for use in casting a metal article includes a furnace assembly into which a mold is raised and an annular fluidized bed adjacent to the furnace assembly. The mold is filled with molten metal and lowered into the fluidized bed. The molten metal is solidified in the mold as it is lowered into the fluidized bed. The mold and fluidized bed are then lowered. The fluidized bed is disposed in a container having annular inner and outer walls which are cooled and function as heat sinks. A mold support member may extend through a passage in the annular inner wall of the fluidized bed.

摘要： An apparatus and method for use in casting a metal article includes a mold structure having wall sections with pins extending between the wall sections. The pins have opposite end portions which are embedded in the wall sections of the mold structure to interlock the pins and the wall sections of the mold structure. When molten metal is poured into the mold structure, the molten metal urges the wall sections away from each other. The wall sections are retained against movement relative to each other by the pins. Although the apparatus and method of the present invention can be utilized to cast many different types of articles, the invention is advantageously utilized in the casting of thin metal articles and specifically a thin metal article which is formed as a single crystal.

摘要： An improved mold for use in casting a metal airfoil has an airfoil mold cavity and a starter chamber. A lower end of the starter chamber is formed by a chill plate. A filter is disposed in the starter chamber between the airfoil mold cavity and the chill plate. When an airfoil is to be cast, molten metal is conducted into the starter chamber, into passages in the filter and into the airfoil mold cavity. The molten metal is solidified upward in the starter chamber from the chill plate and through the passages in the filter. The filter blocks migration of impurities from the starter chamber to the airfoil mold cavity as the metal solidifies in the starter chamber. As the molten metal begins to solidify in the airfoil mold cavity, the molten metal is solidified as a large number of columnar grain crystals which extend from the passages in the filter into the airfoil mold cavity. If a single crystal airfoil is desired, a single crystal selector may be provided between the starter chamber and the airfoil mold cavity.
摘要翻译：用于铸造金属翼型的改进的模具具有翼型模腔和起动室。起动器室的下端由冷却板形成。在翼型模腔和冷却板之间的起动室中布置有过滤器。当要铸造翼型时，熔融金属被引入起动器室，进入过滤器的通道并进入翼型模腔。熔融金属在起动器室中从冷却板向上固化并通过过滤器中的通道。当金属在起动器室中凝固时，过滤器阻止杂质从起动器室迁移到翼型模腔。当熔融金属在翼型模腔中开始凝固时，熔融金属固化成大量的柱状晶粒，其从过滤器中的通道延伸到翼型模腔中。如果需要单晶翼型，则可以在起动器室和翼型模腔之间设置单晶选择器。

摘要： To predict the rate of flow of cooling fluid (gas) through a passage system in a proposed airfoil during operation of a Jet engine, a full size model of the passage system is prepared. The flow of air or other gas is conducted through the model of the passage system. The characteristics of the flow of air or gas through the model of the passage system is determined to enable the characteristics of the flow of cooling fluid through the passage system in the proposed airfoil to be predicted. The model of the cooling fluid passage system in the proposed airfoil is formed by covering the pattern with a layer of metal. The pattern is removed from the covering to form a passage system having a configuration corresponding to the configuration of the cooling fluid passage system in the proposed airfoil.
