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.
Die verschleißfesten Gusserzeugnisse von Kerui werden im Allgemeinen unterteilt in: hochaluminiumhaltige verschleißfeste Gusserzeugnisse, hochfeste verschleißfeste Gusserzeugnisse und schlackenfeste verschleißfeste Gusserzeugnisse.
