<P>PROBLEM TO BE SOLVED: To improve the thermal spalling resistance of a nozzle for a melting pot of refractories for a nozzle apparatus mounted on a molten metal vessel such as a ladle and a tundish, and to improve its corrosion resistance. <P>SOLUTION: One or more kinds selected from alumina-carbon based refractory filler raw materials, 0.2 to 10.0 pts.wt. fine graphite of ≤0.10 mm particle size, 0.1 to 8.0 pts.wt. of one or more kinds selected from metals, and 0.05 to 10.0 pts.wt. of one or more kinds selected from resins as a binder are jointly added. As the alumina-carbon based refractory filler raw materials, alumina, silica, zirconia, magnesia, spinel, or the like, can be used. Further, 5.0 to 10.0 pts.wt. fine graphite of ≤0.1 mm particle size is preferably added. <P>COPYRIGHT: (C)2003,JPO |
