CARBON- CONTAINING REFRACTORY Russian patent published in 2001 - IPC

FIELD: manufacture of carbon-containing refractories used in lining of metallurgical units of furnace-free treatment and transportation of melted metal. SUBSTANCE: carbon-containing refractory is manufactured from blend comprising alumina-containing component, periclase-containing 1-0 mm and less than 0.063 mm fraction component, carbon-containing material, and organic binder. In this case, ratios of 1-0 mm and less than 0.063 mm fractions of periclase-containing and alumina-containing blend components range from (1: 1) to (1:3) at ratios of these components in blend ranging from (1:3) to (2: 1). Blend comprises, wt %: alumina- containing component having 1-8 mm fraction, 50-70; periclase- containing and alumina-containing components having 1-0 mm and less than 0.063 mm fractions, 20-40,; carbon-containing material, 4-14; and organic binder, 3.5-8. Carbon-containing refractory further comprises antioxidant having less than 0.15 mm fraction in amount of 1-5 mm % (above 100% of blend). EFFECT: improved properties of the carbon- containing refractory. 3 cl, 3 tbl
