SK40 Corundum-Based High Alumina Brick are produced with selected bauxite chamotte by advanced process and strict quality control. The main mineral components are corundum and mullite phases. Its features are excellent high temperature mechanics and chemical corrosion resistance.
If Al2O3 content is higher than 90%, it is called corundum brick. Due to different resources, national standards are not completely consistent. For example, European countries have stipulated that the lower limit of Al2O3 content for high-alumina refractories is 42%. In China, according to the content of Al2O3 in high alumina bricks, it is usually divided into three grades: Grade I──Al2O3 content>75%; Grade II──Al2O3 content is 60～75%; Grade III──Al2O3 content is 48～60%.
Production process:
The production methods of SK40 Corundum-Based High Alumina Brick and clay bricks are basically the same.
Aluminum oxide (Al2O3) content is higher than 48% aluminum silicate refractory products.
A neutral refractory with an alumina content of more than 48%.Made of bauxite or other raw materials of high alumina content after molding and calcining.High thermal stability, refractoriness in 1770℃ above.Good slag resistance, used for lining steelmaking electric furnace, glass furnace, cement converter, etc.
High charge soft, SK40 Corundum-Based High Alumina Brick is a high grade refractory material made of super grade bauxite, fused corundum and fused mullite.
Feature
1.SK40 Corundum-Based High Alumina Brick have better thermal conductivity than clay bricks.
2.Because Al2O3 in high aluminum products is high and has less miscellaneous mass, softening temperature under load is higher than clay bricks.
3.The thermal shock resistance of SK40 Corundum-Based High Alumina Brick is between clay and silica products.
Application:
SK40 Corundum-Based High Alumina Brick used for lining blast furnaces, hot blast stoves, electric furnace tops, blast furnaces, reverberatory furnaces, and rotary kilns. In addition, high alumina bricks are also widely used as open hearth regenerative checker bricks, plugs for pouring systems, nozzle bricks, etc. However, the price of high alumina bricks is higher than that of clay bricks, so it is not necessary to use high alumina bricks where clay bricks can meet the requirements.
