MAGNESIA-SPINEL BASED REFRACTORY BRICK
To provide a magnesia-spinel based refractory brick, in which the wear of magnesia-spinel based refractory brick is reduced.SOLUTION: A magnesia-spinel based refractory brick, in which the chemical composition of magnesia-spinel based calcination brick are set at AlO; 5-22 mass%, CaO; less than 2.5 mass% (not including zero), and SiO; 1-5 mass%, and the mass ratio of CaO and SiO(CaO/SiO) at less than 0.6. Thereby, the precipitation of CaSiOfrom the liquid phase component infiltrated into the brick can be inhibited, dusting can be suppressed, and the wear of refractory brick is reduced.SELECTED DRAWING: None
【課題】マグネシア・スピネル質耐火れんがの損耗を低減する。【解決手段】マグネシア・スピネル質焼成れんがの化学組成を、Ａｌ2Ｏ3;５〜２２質量％、ＣａＯ;２．５質量％未満（ゼロを含まず）、ＳｉＯ2;１〜５質量％で、ＣａＯとＳｉＯ2の質量比(ＣａＯ／ＳｉＯ2)を０．６未満とする。これによって、れんが中に浸潤した液相成分からのＣａ2ＳｉＯ4の析出を阻害し、ダスティングを抑制することができ、耐火れんがの損耗が低減される。【選択図】なし
