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.
Kerui wear-resistant castables are generally divided into: high-aluminum wear-resistant castables, high-strength wear-resistant castables and slag-resistant wear-resistant castables.
