Abstract
Composiciones cerámicas de gran valor en la manipulación o moldeado del acero, por ejemplo, como material de revestimiento o para producir toberas orecubrimiento utilizados en los procesos de fundición contínuos que comprenden una mezcla depart ículas de nitruro de boro, diboruro de circonio y, por lomenos, un material refractario adicional, ligadas por el carbono producido por la descomposición de un aglutinante orgánico como por ejemplo, resina o resinade la madera. El materialrefractar io adicional puede ser, por ejemplo, un metal refractario, como un óxido, un carburo, un boruro o un nitruro. Lascomposiciones que contienen óxido de circonio con una proporción del 5-70% por peso de óxido de circonio, 5-60% por pesode diborur o de circonio y 5-80% porpeso de óxido de circonio son especialmente útiles forma la parte de la tobera que se utiliza en el nivel de escoria en un recipiente de acero fundido. Lascomposiciones que contienen óxido de aluminio con unaproporción de 5 -70% por peso de nitruro de boro, 15-50% por peso de diboruro de circonio y 10-70% porpeso de óxido de aluminio son especialmente útiles para formar la parte interna de las toberas puesto que son resistentes a la alúmina que seacumula y evitaque s e formen obstrucciones en la tobera.Ceramic compositions of great value in the handling or molding of steel, for example, as a coating material or to produce nozzles or coating used in continuous casting processes that comprise a mixture of particles of boron nitride, zirconium diboride and, at least , an additional refractory material, bonded by the carbon produced by the decomposition of an organic binder such as resin or wood resin. The additional refractory material may be, for example, a refractory metal, such as an oxide, a carbide, a boride, or a nitride. Compositions containing zirconium oxide with a ratio of 5-70% by weight of zirconium oxide, 5-60% by weight of diborur or zirconium and 5-80% by weight of zirconium oxide are especially useful as part of the nozzle It is used at the slag level in a molten steel container. Compositions containing aluminum oxide with a proportion of 5-70% by weight of boron nitride, 15-50% by weight of zirconium diboride and 10-70% by weight of aluminum oxide are especially useful in forming the inner part of nozzles since they are resistant to alumina that accumulates and prevents blockages in the nozzle.
