BRICK FOR VACUUM DEGASSING APPARATUS AND RH IMMERSION TUBE USING THE SAME
To provide a brick for a vacuum degassing apparatus which is excellent in thermal shock resistance without degrading corrosion resistance; and to provide an RH immersion tube using the same.SOLUTION: A brick for a vacuum degassing apparatus can be obtained by adding an organic binder to a refractory raw material compound, mixing them, molding the resultant mixture, and thereafter heating the molded mixture, wherein: the refractory raw material compound comprises 5 mass% or more and 15 mass% or less of graphite, 40 mass% or more and 70 mass% or less of spinel having a grain size of 1 mm or more and less than 5 mm, and 20 mass% or more and 50 mass% or less of magnesia having a grain size of less than 1 mm. A content ratio of the spinel having the grain size of less than 1 mm is 10 mass% or less (including 0). A content ratio of the magnesia having the grain size of 1 mm or more and less than 5 mm is 5 mass% or less (including 0). An RH immersion tube using the brick is also provided.SELECTED DRAWING: None
【課題】耐食性を低下することなく耐熱衝撃性に優れた真空脱ガス装置用れんが及びこれを使用したＲＨ浸漬管の提供。【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真空脱ガス装置用れんがであって、耐火原料配合物は、黒鉛を５質量％以上１５質量％以下、粒度１ｍｍ以上５ｍｍ未満のスピネルを４０質量％以上７０質量％以下、粒度１ｍｍ未満のマグネシアを２０質量％以上５０質量％以下含有し、かつ、粒度１ｍｍ未満のスピネルの含有率が１０質量％以下（０を含む）、粒度１ｍｍ以上５ｍｍ未満のマグネシアの含有率が５質量％以下（０を含む）である真空脱ガス装置用れんが、及びこの真空脱ガス装置用れんがを使用したＲＨ浸漬管。【選択図】なし
