The first-grade high-alumina refractory brick refers to an aluminum silicate refractory material with a content of not less than 75% aluminum oxide. It is formed and calcined from bauxite or other raw materials with high alumina content.
The refractory brick series mainly has three products: refractory clay bricks, acid-resistant bricks, mullite insulation bricks, refractoriness 1000~1770ºC
It is a weakly acidic refractory material with good thermal shock resistance and corrosion resistance to acidic slag. Generally, clay bricks made of refractory clay as the main raw material are called ordinary clay bricks, and clay bricks made of burnt gemstone clinker as the main raw material, and clay bricks with an apparent porosity below 17% are called low-porosity clay bricks.
Product name: refractory brick
