Aluminum silicon refractory bricks, for those who are not familiar with the refractory materials industry, may be a type of refractory brick containing aluminum and silicon, but for those in the refractory materials industry, there is no such name, only aluminum silicon refractory bricks. So, what is aluminum silicon refractory brick? What is aluminum silicon refractory brick?
Aluminum silicon refractory brick, also known as aluminum silicon refractory brick, is a refractory material product containing Al2O3 and SiO2, and is a series of aluminum silicon refractory bricks. Aluminum silicon refractory bricks have a wide range of applications and occupy an extremely important position in the refractory material application industry, accounting for more than 40% of the total refractory material products.
Aluminum silicon refractory bricks are classified in the order of increasing composition from SiO2 content to Al2O3 content:
(1) Silicon brick: SiO2 content ≥ 93%;
(2) Half silica brick: Al2O3 content of 15% -30%;
(3) Clay brick: Al2O3 content is 30% -48%;
(4) High alumina brick: Al2O3 content ≥ 48%;
(5) Molestone bricks: Al2O3 content ≥ 72%, SiO2 content ≥ 28%;
(6) Corundum brick: Al2O3 content ≥ 90%.
From the classification, it can be seen that silicon bricks, clay bricks, and high alumina bricks are commonly used refractory bricks in kilns, often used for laying the working layer of kilns. Below, we will introduce the application of aluminum silicon refractory bricks.
