摘要： During casting of metal articles, a mold is moved into a body or bath of molten metal. The mold is moved into a container which contains a portion of the body of molten metal. Heat is transferred at a first rate from the mold to a first portion of the body of molten metal disposed above the container. Heat is transferred at a second rate from the mold to the second portion of the body of molten metal at least part of which is disposed in the container. The container retards movement of molten metal relative to the mold to effect an increase in the temperature of the molten metal in the container and thereby retards transfer of heat from a portion of the mold disposed in the container to the body of molten metal. The mold enters the container through an opening at the upper end portion of the container. One or more additional openings may be provided at the lower end portion of the container.

摘要： A Method of casting includes providing a mold having one or more article mold cavities. The mold is moved into a furnace. While the mold is in the furnace, the mold is filled with molten metal. After the mold has been removed from the furnace, a heater is positioned adjacent to the mold and heat is transmitted from the heater to the mold. The heater may include electrically energizable resistance type heating elements, or a source of radiant energy or a gas burner.

摘要： As a mold containing molten metal is lowered from a heating chamber, a baffle extends around the mold. Force is transmitted from the mold to an inner section of the baffle to release connectors between the inner section of the baffle and an outer section of the baffle. As the connectors are released, a side surface on the inner section of the baffle moves out of the coplanar relationship with a side surface on the outer section of the baffle. The baffle may be integrally formed as one-piece. Rather than being formed as one-piece, the baffle may include separate pieces which form the inner and outer sections of the baffle. Alternatively, the inner section of the baffle may be disposed above and supported by the outer section of the baffle. Latches may be provided to interconnect the outer section of the baffle and the furnace assembly.

摘要： The fluidized bed is formed of particulate material suspended in a flow of gas. A flow of particulate suspended in gas is conducted between a lower end portion of the fluidized bed and an upper end portion of the fluidized bed to cool the upper end portion of the fluidized bed. The flow of particulate suspended in gas may be conducted from a lower end portion of the fluidized bed to an upper end portion of a fluidized bed. Alternatively, the flow of particulate suspended in gas may be conducted from the upper end portion of the fluidized bed to the lower end portion of the fluidized bed. If desired, the flow of particulate suspended in gas may be conducted to the upper end portion of the fluidized bed from a location spaced from the fluidized bed.

摘要： An apparatus for use in casting a metal article includes a furnace assembly into which a mold is raised and a 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 mold may be supported on a grid or support member having openings through which gas and particulate in the fluidized bed can flow. A stirrer member may be moved in the fluidized bed to promote uniform distribution of particulate in the flow of gas. Gas may be conducted from the support member for the mold into a container which holds the fluidized bed. Gas at different pressures may be conducted into the fluidized bed at different locations in the fluidized bed. The mold may have a central portion which engages a support member and a peripheral portion, in which article mold cavities are disposed, the peripheral portion of the mold being spaced from the support member to facilitate total immersion of the peripheral portion of the mold in the fluidized bed.

摘要： A mold structure includes an article mold having a mold cavity with a configuration corresponding to the configuration of the article to be cast. A starter section contains a starter cavity in which a plurality of crystals form. A crystal selector has a passage which extends between an upper end of the starter cavity and a lower end of the article mold cavity. To promote the growth in the crystal selector passage of a crystal having primary and secondary orientations corresponding to selected primary and secondary orientations of the article, the crystal selector passage has a portion which slopes downwardly in the direction of solidification of metal along the crystal selector passage. Without the use of a seed crystal, the cast article will have a secondary orientation axis which is almost always within plus or minus 30 degrees of a selected secondary orientation axis. Through the use of a seed crystal, the secondary orientation axis of the cast article will correspond to the selected secondary orientation axis.

摘要： Core material is removed from a passage in a casting by exposing at least a portion of the core material in the passage to a leaching liquid. At least a portion of the core material in the passage is exposed to a gas. An opening to passage is exposed to a gas. At least a portion of the leaching liquid in the passage is boiled while the opening to the passage is exposed to a gas. At least a portion of the leaching liquid is expelled from the passage in the casting by the boiling action. To expose at least a portion of the core material in a passage to a leaching liquid, a flow of leaching liquid is conducted from a reservoir container to an operating container in which the casting is disposed. To expose at least a portion of the core material in the passage to a gas, a flow of leaching liquid is conducted from the operating container to the reservoir container.

摘要： An unfired ceramic base core having a first coefficient of thermal expansion is provided. A core element having a second coefficient of thermal expansion is positioned in an opening formed in the unfired ceramic base core. The opening in the unfired ceramic base core is filled with a filler material having a third coefficient of thermal expansion. The third coefficient of thermal expansion is greater than the first coefficient of thermal expansion and less than the second coefficient of thermal expansion. The ceramic base core is fired without cracking the base core and without cracking the filler material. The ceramic base core contains silica and zircon and has a silica content of 70% or less and a zircon content of 30% or more. The core element may be formed of a ceramic material or a refractory metal.
