MONOLITHIC REFRACTORY FOR MOLTEN ALUMINUM ALLOY
PROBLEM TO BE SOLVED: To provide a monolithic refractory for molten Al alloy excellent in flowability, flexure strength, thermal spalling resistance and infiltration resistance to the molten Al alloy and having higher durability than that of conventional refractory.SOLUTION: A monolithic refractory contains a main raw material and a CaFraw material added to the main raw material. The main raw material consists of SiC raw material of 60 to 98 mass%, a hardening agent of 1 to 15 mass%, an amorphous SiOsuperfine powder of 1 to 8 mass% one or more kinds selected from AlO, CaO, ZrOand MgO which are added to a status with total sum of 100 mass% in the case where the total sum of each component is less than 100 mass%. The CaFraw material is added to the main raw material within a range satisfying ratio between an outer mass% value A of the CaFraw material and a mass% value B of the amorphous SiOsuperfine powder of 0.2≤(A/B)≤2.SELECTED DRAWING: None
【課題】流動性、曲げ強度、耐熱スポーリング性、溶融Ａｌ合金に対する耐浸潤性に優れ、従来の耐火物と比較して高耐用の溶融Ａｌ合金用不定形耐火物を提供する。【解決手段】主原料と当該主原料に添加されるＣａＦ２原料を含む。主原料は、ＳｉＣ原料６０〜９８質量％、硬化剤１〜１５質量％、非晶質ＳｉＯ２超微粉１〜８質量％、上記各成分の総和が１００質量％未満である場合に総和が１００質量％となる状態に添加される、Ａｌ２Ｏ３、ＣａＯ、ＺｒＯ２、ＭｇＯから選ばれる１種類以上の耐火原料からなる。そして、ＣａＦ２原料は、ＣａＦ２原料の外掛け質量％値Ａと非晶質ＳｉＯ２超微粉の質量％値Ｂとの比（Ａ／Ｂ）が０．２≦（Ａ／Ｂ）≦２を満足する範囲内で主原料に添加される。【選択図】なし
