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.
I getti resistenti all'usura Kerui si dividono generalmente in: getti resistenti all'usura ad alto tenore di alluminio, getti resistenti all'usura ad alta resistenza e getti resistenti all'usura da scorie.
