| description | The present invention provides a carbonaceous refractory, and a method of production of the same, which prevents a drop in the molten pig iron corrosion resistance, molten pig iron penetration resistance, and other properties of carbonaceous refractories required for blast furnace bottom refractories and, further, raises the mechanical strength of the refractories so as to suppress cracking due to thermal stress, that is, a carbonaceous refractory characterized by comprising a carbonaceous material comprised of one or more of calcined anthracite, calcined coke, natural graphite, or artificial graphite in 60 to 85 mass%, a refractory metal oxide in 5 to 15 mass%, metal silicon in 4 to 15 mass%, and carbon black in 2 to 10 mass% and by being obtained by adding an organic binder to refractory materials made a total 100 mass%, kneading the materials, then molding them and firing them in a nonoxidizing atmosphere. |
