Definition:

 

High alumina andalusite fused mullite refractory brick is a kind of refractory material. The main component of this refractory brick is Al2O3.


Due to different resources, national standards are not completely consistent. For example, European countries specify a lower limit of 42% for Al2O3 in high aluminum refractories.


In China, the Al2O3 content of high alumina bricks is usually divided into three grades: I etc.-Al2O3 content> 75%; II etc.-Al2O3 content is 60~75%. III etc.-Al2O3 content is 48-60%.

 

Low creep high alumina refractory brick is a neutral refractory with an alumina content of over 48%.


It is formed by firing alumina and other raw materials with high alumina contents. High thermal stability, fire resistance above 1770℃. It has excellent slag resistance and is used for the lining of electric furnaces for steelmaking, glass melting furnaces, cement rotary furnaces, etc.


High load soft low creep high alumina brick is a high quality refractory made from 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 excellent thermal shock stability.

 

Suitable for large and medium-sized hot blast stoves. This opens the next article on the localization of high quality and high quality imported refractory materials needed in China's new hot air stove. The road to success is included in the country's “Spark Project” project.

 

Advantage:

 

 

Good performance in high temp refractoriness under load
Lower thermal line expansion in high temp
Lower impurity content
Good thermal shock resistance performance
Excellent resistance in slag abrasion
Good cold crush strength

 

Application:

 

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

 

Company Profile:

 

Zhengzhou Annec CO., Ltd. was founded in 2003, and has been a NASDAQ listed corporation since 2011 with ticker identification ANNC. Annec had become the industrial leader within China in the areas of refractory production, Engineering for hot blast stove of blast furnace, and capability for EPC project. Annec has its own Provincial Enterprise Technology Center and Top Combustion Hot Blast Stove Research Centre, Annec (Beijing) Engineering & Technology Co., Ltd and four Manufacturers for Refractories. The annual output of different type of refractories can reach 150 thousand tons, and undertaken capability of more than 10 turnkey projects for hot blast
