Abstract

PURPOSE:To obtain a refractory material having excellent corrosion resistant, heat resistance, structural spalling resistance and erosion resistance by mixing carbonaceous materials to lime type refractories in order to improve corrosion resistance for slag of much Fe2O3. CONSTITUTION:A carbon raw material such as graphite, coke or the like is added at 2-70wt% to a mixture of >=1 kinds of electromolten lime, sintered lime, synthetic magdolo clinker or dolomite clinker having undergone grain size controlling. Further an org. binder such as petroleum, petroleum pitch or the like is added to this, and after the mixture is kneaded and molded, the molding is dried or fired, whereby the lime-carbon base refractory material is obtained.
