棕剛玉是一種優質耐火材料,由鋁土礦、鐵屑和焦炭在超過 2000°C 的電弧爐中進行高溫熔煉製成。此製程所產生的氧化鋁質地致密、結晶度高,具有極佳的硬度、強度及耐極端溫度。冷卻之後,材料會被仔細粉碎、篩選並分級成各種尺寸,以符合特定的工業需求。

在耐火材料應用中,褐熔氧化鋁因其優異的熱穩定性、低孔隙率以及出色的耐化學腐蝕和機械磨損性能而備受推崇。其氧化鋁含量高,通常高於 95%,可確保在高爐、水泥窯和煉鋼作業等惡劣環境中的優異性能。

棕剛玉被廣泛用於製造耐火磚、澆注料和整體襯料。它為熔爐、鋼包和坩鍋的襯裡材料提供了極佳的耐久性,可確保在極高的溫度和壓力下延長使用壽命並發揮最佳性能。此外,其抗熔渣和抗熱衝擊的能力使其成為耐火材料工業中不可或缺的材料。

選擇最佳棕剛玉,以獲得可靠、長效的耐火材料解決方案,滿足高溫工業製程的需求。
