Product Description

Product Description

High alumina bricks are aluminum silicate refractory products with an aluminum oxide (Al2O3) content of more than 48%.
A neutral refractory material with an alumina content of more than 48%. It is formed and calcined from bauxite or other raw materials with a high alumina content. It has high thermal stability and a refractoriness of more than 1770ºC. It has good slag resistance and is used for lining steelmaking electric furnaces, glass melting furnaces, cement rotary furnaces, etc.
High-load soft, low-creep high-alumina bricks are advanced refractory materials made from special-grade bauxite, fused corundum, and fused mullite as the main raw materials. This product has the advantages of small high-temperature creep, strong erosion resistance, and good thermal shock stability, and is suitable for large and medium-sized hot blast furnaces.
