摘要： There is provided an apparatus and method for the manufacture of metallic articles. A molten metal stream is disrupted, such as by gas atomization, to form a plurality of molten metal droplets. The molten metal droplets pass through a cooling zone having a length sufficient to allow up to about 30 volume percent of each of the droplets to solidify. A mold then receives and completes solidification of the metal droplets. When under about 30 volume percent of the droplets is solid, the droplets retain liquid characteristics and readily flow within the mold.

摘要： The present invention relates to a technique for forming silicon carbide coated porous filters for use in filtering molten metal, especially copper and copper alloy melts. The technique comprises preparing a silicon carbide containing slurry having a viscosity in the range of about 1 to about 50, preferably from about 5 to about 30, centipoise and impregnating a rigid porous substrate material with the slurry. In a preferred embodiment, the slurry contains mono-aluminum phosphate as a binding agent, ethylene glycol as a wetting agent, powdered silicon carbide having a maximum settling rate of about 0.1 mm./min. and the balance essentially water. After draining of the excess slurry, the coated substrate material is heated to substantially prevent foaming of the coating during firing and fired to bond the silicon carbide coating to the substrate material.

摘要： A process and apparatus is described for slurry casting an ingot having a non-dendritic structure across substantially its entire cross section. The casting mold has a first chamber for extracting heat from the molten material. The amount of heat extracted from the molten material and the cooling rate of the molten material is controlled to initiate growth of primary phase particles and to form a semi-solid slurry having a desired fraction solid. The mold also has a second chamber for casting the slurry into an ingot. Adjacent the exit portion of the first chamber and the inlet portion of the second chamber, a transition member is provided for delivering the slurry to the casting chamber and for preventing the ingot shell from extending back into the first chamber.
