摘要： A launder for use in moving molten metal includes at least one relatively narrow channel through which molten metal flows. Using a narrow, rather than broad, channel permits better control of the flow and helps prevent overflowing the launder or a structure adjacent the launder. A molten metal pumping or transfer system may utilize a launder as disclosed herein.

摘要： A counter gravity casting apparatus includes a reusable metal mold having a plurality of mold cavities, a feed tube configured to feed molten alloy into the mold, and a vacuum fitting configured to permit a vacuum to be applied to the mold. The mold includes multiple metal sections configured such that adjacent metal sections mate to one another, the metal sections being separable from one another. The metal sections include recesses that form the mold cavities, and the mold includes a sprue and multiple runner passages. The sprue is configured to receive molten alloy from the feed tube, and the multiple runner passages are configured to feed molten alloy from the sprue to the mold cavities. Methods of casting bulk amorphous alloy articles or feedstock is described.

摘要： An exemplary embodiment of the invention provides a method of preparing a reinforced refractory joint between refractory sections of a vessel used for containing or conveying molten metal, e.g. a metal-contacting trough. The method involves introducing a mesh body made of metal wires into a gap between metal-contacting surfaces of adjacent refractory sections of a vessel so that the mesh body is positioned beneath the metal conveying surfaces, and covering the mesh body with a layer of moldable refractory material to seal the gap between the metal-contacting surfaces. Other embodiments relate to a vessel formed by the method and a vessel section with a pre-positioned mesh body suitable for preparing a sealed joint with other such sections.

摘要： Exemplary embodiments of the invention provide a vessel for containing or conveying molten metal therein. At least part of the outer surface of the vessel incorporates a web of metal wires embedded in the surface, the wires being mutually overlaid with openings formed therebetween. The refractory material penetrates into the openings. The web may comprise woven metal wires or non-woven wires or both. The web imparts resistance to cracking (or containment of cracks, once formed) and/or resistance to molten metal leakage if cracks develop. The invention also provides metal containment structures containing such vessels, and methods of producing the same.
