High alumina brick is a kind of refractory material, the main component of this kind of 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.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%.
The production process of high-alumina bricks and multi-clinker clay bricks is similar. The difference is that the proportion of clinker in the ingredients is higher, which can be as high as 90~95%. The clinker needs to be classified and screened before being broken. Higher, such as I, II and other high alumina bricks are generally 1500~1600 ºC when fired in tunnel kiln.
