    Abstract: PROBLEM TO BE SOLVED: To provide a carbon-containing refractory having excellent slag resistance as well as excellent thermal shock resistance by a means where uniform dispersion is relatively simply made possible when carbon nanofibers are dispersed into a refractory for reducing carbon in a carbon-containing refractory. SOLUTION: Using, as raw materials, a catalyst-covered refractory raw material in which the surface of a refractory raw material is coated with one or more kinds of metals selected from the group consisting of V, Fe, Co, Ni, Cu, Mo, Pd, Rh, W and Pt, the oxide or metal salt of the metal(s), and an organic polymer resin or the precursor thereof, they are kneaded, molded and heat-treated, so as to be a nanocarbon-containing refractory in which nanocarbon tubes are uniformly dispersed into the structure.

    Abstract: PROBLEM TO BE SOLVED: To provide a carbon-containing refractory having both excellent strength and thermal shock resistance, keeping excellent slag infiltration resistance and having sufficient durability. SOLUTION: The carbon-containing refractory is produced by adding ≤5 mass% fullerene in outer percentage and 0.5-5 mass% pitch in outer percentage with a thermosetting organic resin as an organic binder into magnesia based, spinel based, alumina based refractory raw material powder, kneading, forming and heat-treating. In the carbon-containing refractory, carbon nanofiber having 5-10 nm diameter and 100-300 nm length and is present in a bonded structure and the carbon-containing refractory is used suitably for a dipping nozzle or a long nozzle.
