Aluminum silicate refractory products with aluminum oxide (Al₂O₃) content higher than 48%.

A neutral refractory with an alumina content of more than 48%. It is formed and calcined from bauxite or other raw materials with high alumina content. High thermal stability, refractoriness above 1770℃. It has good slag resistance and is used for the lining of steelmaking electric furnaces, glass melting furnaces, cement rotary furnaces, etc.

High-load soft, low-creep high-alumina bricks [1] are high-grade refractories made of super-grade bauxite, fused corundum, and fused mullite as the main raw materials. This 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 stoves. It opens up the next article for the localization of high-quality and high-grade imported refractory materials for new hot blast stoves in my country. The road to success has been included in the national "Spark Plan" project.
