Product Description
Description of High Temperature resistance High Alumina Brick Curved Arched Fire Brick Insulating Fireclay Refractory For furnace
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.
