MAGNESIA-CARBON BRICK AND MOLTEN STEEL LADLE USING THE SAME
PROBLEM TO BE SOLVED: To improve the oxidation resistance of a magnesia-carbon brick, particularly a magnesia-carbon brick used for a slag line part of a molten steel ladle.SOLUTION: A refractory raw material compound contains: 65-97 mass% of electrofused magnesia containing CaO of 0.3-3 mass% and SiOof 0.4-3 mass%; graphite of 1-30 mass%; and silicon carbide of 1-6 mass%. The refractory raw material compound is mixed with an organic binder and molded. The molded product is then dried to make a magnesia-carbon brick 3, which is to be put in a slag line part 2 of a molten steel ladle 1.SELECTED DRAWING: Figure 1
【課題】マグカーボンれんが、特に溶鋼鍋のスラグライン部に使用されるマグカーボンれんがの耐酸化性を向上する。【解決手段】ＣａＯを０．３〜３質量％及びＳｉＯ２を０．４〜３質量％を含有する電融マグネシアを６５〜９７質量％、黒鉛を１〜３０質量％、並びに炭化珪素を１〜６質量％含む耐火原料配合物を、有機バインダーとともに混練、成形した後、乾燥して得られるマグカーボンれんが３を溶鋼鍋１のスラグライン部２に設置する。【選択図】図１
