High Alumina Insulating Refractory Fire Brick is a kind of refractory material, the main component of this refractory brick is AL2O3. 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 set the lower limit of Al2O3 content for high-alumina refractories at 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%
High alumina bauxite is used as the main raw material, clinker is sorted by grading and sieved to remove iron, and is prepared by high temperature firing.
Application: Blast furnace, hot blast stove, electric furnace top and ladle permanent lining
