Zusammenfassung: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.
