High Alumina Bricks is made of high-quality bauxite clicker as starting material by gaping at high pressure and sintering at high temperature.
High Alumina Bricks are mainly used in furnace for glass, each position of linings of blast furnace.
The main applications are :
|Cold Crusing Strength ≥||60||55||40|
|Apparent Porosity(%) ≤||20||22||23|
|Bulk Density(g/cm*) ≥||2.5||2.4||2.3|
|0.2MPa Refractoriness Under Load ≥||1500||1470||1450|
|Refiring Linear Change||0~-0.2||0~-0.2||±0.2|
