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.
Los hormigones resistentes al desgaste Kerui se dividen generalmente en: hormigones resistentes al desgaste de alto contenido en aluminio, hormigones resistentes al desgaste de alta resistencia y hormigones resistentes al desgaste resistentes a la escoria.
