CASTABLE REFRACTORY FOR BLAST FURNACE TROUGH
To enhance the generation of 9AlO2BO(9A2B) in a castable refractory for blast furnace trough.SOLUTION: A castable refractory for blast furnace trough contains alumina and/or silicon carbide, carbon raw material, and boron carbide, in which, when total amount of whole particles is set to 100 mass%, the castable refractory for blast furnace trough contains 5 to 36 mass% of alumina with a particle diameter of less than or equal to 75 μm, 0.3 to 4 mass% of boron carbide, calcium oxide of less than or equal to 0.5 mass% (including zero), carbon raw material of less than or equal to 10 mass%, and 5 to 15 mass% of an inorganic colloidal liquid by outer percentage.SELECTED DRAWING: Figure 1
【課題】高炉樋用キャスタブル耐火物中の９Ａｌ2Ｏ3・２Ｂ2Ｏ3（９Ａ２Ｂ）の生成を促進する。【解決手段】アルミナおよび／または炭化けい素と、カーボン原料と、炭化ほう素を含む高炉樋用キャスタブル耐火物であって、全粒子の合量を１００質量％としたとき、粒径７５μｍ以下のアルミナが５〜３６質量％、炭化ほう素が０．３〜４質量％、酸化カルシウムが０．５質量％以下（ゼロを含む）、カーボン原料が１０質量％以下であり、さらに無機コロイド液を外掛けで５〜１５質量％含むことを特徴とする高炉樋用キャスタブル耐火物。【選択図】図１
