Product Description of Factory Wholesale Price High Alumina Refractory Brick RS-55 RS-65 RS-75 Alumina Brick For Steel And Glass Furnace

High alumina brick is an alumina-silicate refractory material containing over 48% alumina oxide. It is produced through the calcination and molding of bauxite or materials with a high AL2O3 content. It exhibits excellent thermal stability with a refractoriness exceeding 1770℃. Additionally, it offers strong resistance to slag, making it ideal for lining steel-making electric furnaces, glass furnaces, and cement kilns.
