Description of High Percentage Alumina Ceramic Bricks High Alumina Refractory Brick For Steelmaking Electric Furnaces

High alumina brick is a refractory material composed of over 48% alumina oxide, classified as an alumina-silicate. It is produced through the calcination and molding of bauxite or materials rich in AL2O3. Exhibiting exceptional thermal stability, it boasts a refractoriness exceeding 1770℃. With superior resistance to slag, it finds applications in lining steelmaking electric furnaces, glass kilns, and cement rotary kilns.
