Product Description

High Alumina Fireclay Refractory Brick for Steel Making Nozzle Brick
The Description:
If the Al2O3 content is higher than 90%, it is called corundum brick. Due to different resources, national standards are not entirely consistent. For example, European countries stipulate that the lower limit of Al2O3 content for high aluminum refractories is 42%. In China, according to the Al2O3 content in high aluminum bricks is usually divided into three grades: 1 .-- Al2O3 content >75%; 2.-al2o3 content is 60 ~ 75%; 3. -- Al2O3 content is 48 ~ 60%.
