High Alumina Special-shaped Hanging Bricks
high alumina special-shaped hanging bricks 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.. 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.

Introduction to high alumina special-shaped hanging bricks
high alumina special-shaped hanging bricks 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.. 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.
Product performance of high alumina special-shaped hanging bricks
1. Refractoriness of high alumina special-shaped hanging bricks
The refractoriness of high alumina special-shaped hanging bricks is higher than that of clay bricks and semi-silica bricks, at 1750~1790℃, which belong to advanced refractory materials.
2. Load softening temperature of high alumina special-shaped hanging bricks
Because high-alumina products have high Al2O3, less impurities, and less fusible glass bodies, the load softening temperature is higher than that of clay bricks. high alumina special-shaped hanging bricks, but because mullite crystals do not form a network structure, there is still no silicon at the load softening temperature. Brick high.
3. Slag resistance of high alumina special-shaped hanging bricks
high alumina special-shaped hanging bricks contain more Al2O3, which is close to neutral refractory materials, and can resist the erosion of acidic slag and alkaline slag. Because of the inclusion of SiO2, the ability to resist alkaline slag is weaker than that of acidic slag.
If Al2O3 content is higher than 90%, it is called corundum brick.
2. Classification of high alumina special-shaped hanging bricks by firing process
It can be divided into fired high alumina special-shaped hanging bricks and unfired high alumina special-shaped hanging bricks. The firing temperature of the first and second grade high alumina special-shaped hanging bricks is 1500℃-1600℃ and 1450℃-1500℃ respectively, while the third grade is lower. High-alumina non-sintered bricks mainly refer to phosphate high-alumina.
3. Classification of high alumina special-shaped hanging bricks by mineral composition
It can be divided into five types: low mullite, mullite, mullite, corundum, corundum and corundum;
4. Classification of high alumina special-shaped hanging bricks according to different shapes
It can be divided into standard high alumina special-shaped hanging bricks, special-shaped high alumina special-shaped hanging bricks and special high alumina special-shaped hanging bricks;
5. Classification of high alumina special-shaped hanging bricks according to their properties
It can be divided into ordinary high alumina special-shaped hanging bricks and special high alumina special-shaped hanging bricks (thermal shock resistance, low creep, anti-stripping high alumina special-shaped hanging bricks;
6. Classification of high alumina special-shaped hanging bricks by use
It can be divided into high-aluminum and high-alumina bricks, hot-blast stove high-alumina bricks, steel-making electric furnace top high-alumina bricks, Shenggang barrel high-alumina bricks, and inner cast high-alumina bricks.
