Little MgO Content High Alumina Brick for Blast Furnace from Chinese

Chinese supplier high quality high alumina brick used for blast furnace

Introduction to high alumina bricks

Aluminum refractory products with aluminum oxide (Al2O3) content higher than 48%.
A neutral refractory with an alumina content of more than 48%. It is formed and calcined from bauxite or other raw materials with high alumina content. High thermal stability, refractoriness above 1770℃. It has good slag resistance and is used for the lining of steelmaking electric furnaces, glass melting furnaces, cement rotary furnaces, etc.
High-load soft, low-creep high-alumina bricks [1] are high-grade refractories made of super-grade bauxite, fused corundum, and fused mullite as the main raw materials.

High alumina brick is a kind of neutral refractory material with alumina content above 48%. It is formed and calcined from alumina or other raw materials with high alumina content. High thermal stability, refractoriness above 1770℃. It has good slag resistance and is used for lining steel-making electric furnaces, glass melting furnaces, cement rotary furnaces, etc.

High alumina brick is a kind of refractory material. It is an aluminum silicate refractory product with aluminum oxide (Al2O3) content higher than 48%. The main component of this refractory brick is AL2O3

Classification of high alumina bricks

1. Classified by Al2O3 content in high alumina bricks

Class Ⅰ-Al2O3 content>75%

Class Ⅱ-Al2O3 content is 60~75%

Class Ⅲ-Al2O3 content is 48-60%.

If Al2O3 content is higher than 80%, it is called super high alumina brick

If Al2O3 content is higher than 90%, it is called corundum brick.

Characteristics of high alumina refractory brick:
1. High refractoriness.
2. Good spalling resistance and wear resistance.
3. Good corrosion resistance.
4. Good thermal shock resistance.
5. High mechanical strength.
6. High-temperature creep rate is low.

a. Refractoriness
The refractoriness of high-alumina bricks is higher than that of clay bricks and semi-silica bricks, reaching 1750~1790℃, which belongs to advanced refractory materials.
b, load softening temperature
Because of the high Al2O3 in high alumina products, less impurities and less fusible glass body, the softening temperature under load is higher than that of clay bricks, but because mullite crystals do not form a etwork structure, the softening temperature under load is still lower than that of silica bricks.
c. Slag resistance
There are more Al2O3 in high alumina bricks, which are close to neutral refractory materials, and can resist the erosion of acidic slag and alkaline slag.
