Definition:

   Aluminum Silicate Refractory Brick the main chemical components: Al2O3 content is 30%-48%, SiO2 content is 50%-65%, and a small number of alkali metals, alkaline earth metal oxides, etc. Mineral composition is usually mullite, quartz and glass phase. Its refractoriness is 1580-1750℃, refractoriness under load is 1250-1450 ℃, line expansion coefficients is low, with good thermal shock resistance and strong ability to resist erosion acid slag.

 

     Aluminum Silicate Refractory Brick is a neutral refractory with alumina content above 48%.


    It is formed by calcining alumina and other raw materials with high alumina content. High thermal stability, fire resistance above 1770℃. It has good slag resistance and is used for lining steel-making electric furnaces, glass melting furnaces, cement rotary furnaces, etc.


    High-load soft, low-creep high-alumina brick is a high-grade refractory material made of super-grade alumina, fused corundum, and fused mullite as the main raw materials.


    This product has the advantages of low temperature creep, strong corrosion resistance and good thermal shock stability.

 

    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 required by China's new hot blast stoves. The road to success has been included in the national "Spark Project" project.

 

Advantage:

 

   

1. Good thermal shock stability,

2. High temperature mechanical strength;

3. High softening temperature under load,

4. Good slag resistance and alkali salt resistance

 

Application:

    

   

•Industrial furnace, glass furnace
• Chemical industrial furnace
• Utility industry furnace lining
• Heat insulation ventilation wall
