Product Details

Product Description of Customized Special Shapes Fan-shaped High-alumina Brick High Alumina Curved Brick For Hot Blast Stove Roof

High alumina bricks refer to aluminosilicate refractory products with aluminum oxide (Al2O3) content higher than 48%. It belongs to neutral refractory material. It is formed by shaping and calcining bauxite or other raw materials with high alumina content. High thermal stability and fire resistance above 1770 ℃. It has good slag resistance and is used for lining steel making electric furnace, glass furnace, cement rotary furnace, etc.

High load soft and low creep high alumina brick is a high-grade refractory material made of special grade bauxite, fused corundum and fused mullite. The product has the advantages of small high-temperature creep, strong corrosion resistance, good thermal shock stability, etc. It is suitable for large and medium-sized hot blast furnaces.

Advantage of High Alumina Curved Brick For Hot Blast Stove Roof

1. High refractoriness;

2. High temperature strength;

3. High thermal stability;

4. Neutral refractory;

5. Good resistance to acid and basic slag corrosion;

6. High refractoriness under load;

7. High temperature creep resistance;

8. Low apparent porosity;

Application of high alumina bricks

As a basic material in the field of high-temperature technology, high alumina bricks are widely used in cement, glass building materials, steel smelting, petrochemical and other industries. High temperature industrial furnaces for high alumina bricks include blast furnace, hot blast furnace, electric furnace, blast furnace, reverberatory furnace and rotary kiln lining. In addition, high alumina bricks can also be processed into open hearth regenerative grid bricks, socket bricks for pouring system, nozzle bricks, etc. according to the requirements of industrial furnaces.
