Molten metal-containing vessel and methods of producing same

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.

1. A vessel for molten metal, the vessel comprising a body of refractory material having a cavity for containing or conveying molten metal, and an outer surface having a web of metal wires embedded therein, said wires being overlaid with respect to each other with openings formed between said wires into which openings said refractory material penetrates, wherein the web of metal wires comprises at least two overlying web sections, one of the web sections comprising a woven matrix of metal wires for providing structural reinforcement to the refractory material and another of the web sections comprising a non-woven matrix of metal wires including a plurality of metal wires overlying one another in a random fashion and matted together to define a plurality of openings having an average width in a range of 50 μm to 350 μm and a plurality of convoluted paths across a thickness of the non-woven matrix for resisting penetration of the molten metal through the non-woven matrix of metal wires.
