Product Description

High Quality 48-90% Al2O3 Alumina Silica Fire Brick 230*114*65mm High Alumina Refractory Bricks For Electric Arc Furnace Roof

High Alumina Refractory Bricks

High alumina bricks refer to aluminosilicate refractory products with aluminum oxide (Al2O3) content higher than 48%. It belongs to neutral refractory material. It is formed by shaping and calcining bauxite or other raw materials with high alumina content. High thermal stability and fire resistance above 1770 ℃. It has good slag resistance and is used for lining steel making electric furnace, glass furnace, cement rotary furnace, etc.

High load soft and low creep high alumina brick is a high-grade refractory material made of special grade bauxite, fused corundum and fused mullite. The product has the advantages of small high-temperature creep, strong corrosion resistance, good thermal shock stability, etc. It is suitable for large and medium-sized hot blast furnaces.
