METHOD FOR PRODUCING MAGNESIA-CHROME BRICK
To provide a method for producing a magnesia-chrome brick having a dense structure, in which a structural spalling hardly occurs.SOLUTION: After kneading a refractory raw material compound, a kneaded product is molded and fired at 1,700°C or more, the refractory raw material comprising: 50 to 96 mass% of magnesia-chrome clinker; 40 mass% or less (including 0) of magnesia clinker; 3 to 10 mass% of chromium oxide; and 1 to 5 mass% of a zirconia raw material containing 3 to 50 mass% of CaO or MgO.SELECTED DRAWING: None
【課題】構造的スポ―リングが生じ難い組織の緻密なマグクロれんがの製造方法を提供する。【解決手段】マグクロクリンカーを５０～９６質量％、マグネシアクリンカーを４０質量％以下（０を含む。）、酸化クロムを３～１０質量％、及びＣａＯ又はＭｇＯを３～５０質量％含有するジルコニア原料を１～５質量％含有する耐火原料配合物を混練後、成形し、１７００℃以上で焼成する。【選択図】なし
