Wear – resistant castables are refractory materials designed to endure high – intensity abrasion. Composed of wear – resistant aggregates, binders, and additives, they feature excellent hardness and toughness, effectively protecting equipment surfaces in harsh working conditions.
케루이 내마모성 캐스터블은 일반적으로 고알루미늄 내마모성 캐스터블, 고강도 내마모성 캐스터블, 슬래그 내마모성 캐스터블로 구분됩니다.
