Abstract

본 발명은 용융금속, 특히 용강에 대한 부식, 침식 및 마모에 강하여 용강등의 용융금속과 접촉하여 사용하는 열전대 보호관, 롤러, 노즐 등의 부재로서 적용할 수 있는 용강 내식성 소재 및 그 제조방법에 관한 것으로, 용강 내식성 소재의 원료를 ZrB2와 메조페이즈 핏치의 혼합물로 조성하고 이를 소성하므로서, ZrB2자체의 난소결성을 해소하고 동시에 용융금속 및 용강에 대한 내침식성이 우수한 소재 및 이를 제조하는 방법을 제공하고자 하는데, 그 목적이 있다.
상기한 목적을 달성하기 위한 본 발명은 ZrB2: 85-98중량%과 메조페이즈 핏치 : 2-15중량%로 조성되는 용강 내식성 소재 및 그 제조방법에 관한 것을 요지로 한다.
