Abstract
To provide a long-life refractory capable of maintaining durability under severe conditions. The castable refractory comprises a mixture containing at least one of 2 to 10 mass % of silicon carbide and 3 to 10 mass % of chamotte, as an auxiliary raw material, and a binder material, with the remaining balance being one or more main raw materials selected from corundum, mullite, bauxite, chamotte, talc and silica, and is used in an environment exposed to an alkali component-containing hot gas atmosphere. In an alkali component-containing gas atmosphere at a high temperature (750° C. or more), silicon carbide and/or chamotte are vitrified to a thickness of 1 mm or less in the surface layer of the refractory to prevent the alkali component-containing gas from intruding inside of the refractory.
