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耐摩耗性キャスタブルは一般的に、高アルミニウム耐摩耗性キャスタブル、高強度耐摩耗性キャスタブル、耐スラグ耐摩耗性キャスタブルに分けられる。
