Abstract

본 발명은 고온, 산화분위기 조건하에서도 슬러그 분해에 대해 안정적이며 철 함유량이 높은 슬러그에 대해서도 우수한 내식성을 나타내는 고순도 전융마그네시아 클링카로 이루어진 내화재와, 이 내식성이 우수한 전용 마그네시아 클링카를 사용하여 내식성과 함께 내스폴링성도 우수한 소성 혹은 불소성 연와를 제공한다.
MgO 함유량이 98.0~99.8중량% 이고, SiOz함유량이 0.05중량% 이하이며, CaO 함유량이 0.1~2.0 중량%인 전융마그네시아 클링카로 이루어진 내화재료이며, 이를 10중량% 이상 함유시켜 소성, 불소성 혹은 부정형 내화물을 얻는다.
