BRICK FOR HOT METAL LADLE, AND HOT METAL LADLE LINED WITH THE SAME

To provide a brick for a hot metal ladle, which is excellent in corrosion resistance and has residual expansion properties, and to provide the hot metal ladle lined with the same.SOLUTION: A brick for a hot metal ladle is obtained by adding an organic binder to a refractory raw material compound, mixing them, molding the resultant mixture, and then heating the molded mixture. The refractory raw material compound comprises: 5 mass% or more and 20 mass% or less of a silica having a particle size of 1 mm or more and less than 5 mm; 45 mass% or more and 80 mass% or less of an alumina-based raw material; 5 mass% or more and 20 mass% or less of graphite; and 0.3 mass% or more and 4 mass% or less of aluminum and/or aluminum alloy, wherein a content ratio of silicon carbide is 20 mass% or less (including 0), a content ratio of pyrophyllite having a particle size of 1 mm or more and less than 5 mm is 10 mass% or less (including 0), and when the brick comprises the pyrophyllite having the particle size of 1 mm or more and less than 5 mm, the total of the content ratio of pyrophyllite and a content ratio of silica having the particle size of 1 mm or more and less than 5 mm is 20 mass% or less. The brick is lined to the hot metal ladle.SELECTED DRAWING: None 【課題】耐食性に優れしかも残存膨張性を有する溶銑鍋用れんが及びこれをライニングした溶銑鍋を提供する。【解決手段】耐火原料配合物に有機バインダーを添加して混練し成形後、熱処理して得られる溶銑鍋用れんがである。耐火原料配合物は、粒度１ｍｍ以上５ｍｍ未満の珪石を５質量％以上２０質量％以下、アルミナ質原料を４５質量％以上８０質量％以下、黒鉛を５質量％以上２０質量％以下、並びにアルミニウム及び／又はアルミニウム合金を０．３質量％以上４質量％以下含有すると共に、炭化珪素の含有率が２０質量％以下（０を含む）、粒度１ｍｍ以上５ｍｍ未満のろう石の含有率が１０質量％以下（０を含む）であり、かつ、粒度１ｍｍ以上５ｍｍ未満のろう石を含有する場合、粒度１ｍｍ以上５ｍｍ未満の珪石の含有率との合計が２０質量％以下である。このれんがを溶銑鍋にライニングする。【選択図】なし
