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.

Molten metal-containing vessel, and methods of producing same

A curvilinear metal transfer device with support and compression assemblies that help maintain a constant force on the transfer device's metal outer casing and refractory as the outer casing and refractory expand and contract due to temperature fluctuations. In one embodiment, the support assemblies are configured to apply force to the refractory to keep the refractory in tension with the outer casing to suspend the refractory relative the outer casing. Also disclosed are clamp plates that help hold the refractory in place, and nested lids that cover the curvilinear metal transfer device.

Molten metal-containing vessel and methods of producing same

A method is described for improving resistance to chemical attack by aluminum or magnesium in refractory components. In one method, a slurry is formed comprising calcium silicate-containing refractory material and a barium-containing compound. This slurry is placed in a mold, then dewatered to form a component which is hydrothermally processed to form a final component. In a second procedure, a silica-containing porous refractory component is impregnated with an aqueous solution of an oxide or hydroxide of barium or strontium and thereafter dried in air.

Method for suppressing reaction of molten metals with refractory materials

Lithium feed to an aluminum-lithium alloy production system is achieved at a highly controlled rate by advancing a plunger at a predetermined volumetric rate into a body of molten lithium retained in a holding vessel to displace the lithium toward an overflow port through which it is fed into a mixing vessel where it is combined with molten aluminum. Control of the aluminum feed rate is achieved by maintaining a constant head height upstream of an orifice. The thus metered streams of molten lithium and aluminum are then combined in a vortex bowl, whose outlet is then fed to a casting station.
