High Alumina Bricks
High alumina brick is a kind of refractory material. The main component of this refractory brick is Al2O3.
If the 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 stipulate that the lower limit of Al2O3 content for high-aluminum refractory materials is 42%. In China, high alumina bricks are usually divided into three grades according to the Al2O3 content: Grade I - Al2O3 content >75%; Grade II - Al2O3 content is 60-75%; Grade III - Al2O3 content is 48-60%.

Industry Kiln
Mainly used for lining blast furnaces, hot blast furnaces, electric furnace roofs, 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.
A neutral refractory material with an alumina content of more than 48%. It is formed and calcined from alumina or other raw materials with high alumina content. It has high thermal stability and refractoriness above 1770℃. It has good slag resistance and is used for lining steelmaking electric furnaces, glass furnaces, cement rotary furnaces, etc.
