Abstract
A refractory castable composition is disclosed comprising one hundred weight percent of a refractory composition comprising from about 60 to 90 weight percent of a refractory aggregate, from about 2 to 25 weight percent of an ultrafine refractory material having an average particle diameter size less than or equal to about 3 microns, from about 0.5 to 15 weight percent of a binder, and from about 0.05 to 2.0 weight percent of a dispersant, wherein all or a portion of the ultrafine refractory material comprises a thermal black such that the refractory composition comprises from about 2 to 15 weight percent of the thermal black, and from about 3 to 10 weight percent water based upon 100 weight percent of the refractory composition, and wherein the water is present in an amount sufficient to achieve a castable consistency. A method of installing the refractory castable composition is also disclosed.
