| 16 | Anti-alumina-buildup refractories for casting nozzles | US13136850 | 2011-08-12 | US20110297707A1 | 2011-12-08 | Koji Ogata; Donald Bruce Hoover |
| Disclosed is anti-alumina-buildup refractories for casting nozzles, which comprises a refractory aggregate including 20 mass % or more of CaO component, and 10 mass % or more of clinker particles each containing CaO as a mineral phase, on the basis of 100 mass % of the entire composition. At least a part of the surfaces of the CaO exposed from the surfaces of the corresponding clinker particles is formed with a CaCO3 film. The CaCO3 film releases CO2 gas through thermal decomposition to smooth an operative surface of the nozzle so as to prevent the accretion of metal thereon, so that CaO is continuously supplied to alumina attached on the operative surface to prevent alumina buildup. In addition, the CaCO3 film effectively prevents the hydration of CaO due to a hydration reaction. | ||||||

| A method of producing an immersion nozzle for continuous casting, which includes integrally molding a first zirconia-graphite compound applied to a powder-line portion of the nozzle, and a second compound applied to at least an inner hole portion of the nozzle. The second compound includes 10 mass % or more of clinker particles each containing CaO as a mineral phase, and the surface of at least a part of the clinker particles is subjected to an anti-hydration treatment, such as a heat treatment to be performed under a CO2 atmosphere to convert CaO to CaCO3. The method can suppress volume expansion caused by the reaction between CaO and water released from resin added as binder, so as to prevent the occurrence of cracks during a burning process of the molded piece. | ||||||

| The invention describes an article and method comprising a refractory article having an outer surface covered by an insulating coating over which a protective glaze is applied. The method includes applying a suspension of an insulating coating to a refractory piece, drying the suspension, applying a glaze slip over the coating, and drying the slip to form a protective glaze. In one embodiment, the article comprises a carbon-bonded alumina-graphite nozzle, an insulating coating containing hollow microspheres, and a protective glaze formed from a fusible frit. The invention is described as improving wetting to the refractory piece, reducing delamination of the glaze and insulating coating from the piece, and reducing oxidation of the piece. | ||||||

| A permeable, resin-bonded composition is described, which finds utility as a porous element in a gas-injection nozzle. The permeable composition is notably useful in a canless, resin-bonded, gas-injection nozzle, characterized by an impermeable, resin-bonded composition replaces the metal can. Advantageously, the resin-bonded compositions include an oxygen getter for scrubbing oxygen before the oxygen can reach the molten steel. A method of manufacturing the nozzle is described and includes copressing a standard, resin-bonded composition around the permeable, resin-bonded composition. The pressed piece may be cured at temperatures below about 800° C. | ||||||
