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

Form: Solid
Material: refractory clay, burnt gemstone clinker, etc.
Product features: low apparent porosity, strong anti-permeation and anti-erosion capabilities
Main application: used in steel, glass, chemical industry and other industries.

Product Features
High thermal stability, refractoriness above 1790°C, high load softening temperature above 1480°C, good slag resistance, good thermal shock stability, acid and alkali resistance, low high temperature creep rate, high temperature strength, etc.

Applications
First-grade high-alumina refractory bricks are mainly used in lime kiln (high temperature zone), electric furnace cover (furnace top), blast furnace (furnace body), hot blast furnace partition wall, ladle lined with steel drum, cement kiln, glass kiln, etc. Various therma
