PURPOSE:To improve oxidation resistance and corrosion resistance of a carbon- containing refractories without reducing spalling resistance or hot strength. CONSTITUTION:To a refractory raw material containing 5 to 90wt.% carbonaceous raw material and 10 to 95wt.% alumina refractory raw material, an Al-Ti alloy powder having an atomic ratio of Al to Ti within a range of (25/1) to (1/25) is added in an amount of 0.1 to 10 outer wt.%. |
