Abstract

본 발명의 목적은 내스포올링성, 내식성 및 내슬랙 침윤성이 뛰어난 알루미나-스피넬질 부정형 내화물을 제공하는데 있다.
본 발명의 알루미나-스피넬질 부정형 내화물은 MgO:Al2O3몰비가 0.14:1.86 ~ 0.6:1.4의 범위 내에 있는 알루미나-스피넬질 클린커를 사용하는 것이며, 또 이 알루미나-스피넬질 클린커와 거의 이론 조성의 스피넬 클린커를 병용할 수도 있고, 잔부를 알루미나 원료와 알루미나 시멘트로 구성하는 것이다.
또한, 본 발명의 알루미나, 스피넬질 부정형 내화물에는 입도 10~50㎜의 알루미나 분쇄입을 배합하여 균열의 신장을 억제할 수도 있다.
