FUSED CAST BRICK
CMAX Bricks made from high quality quartz tail sand, lime and mineralizing agent through the process of crashing, screening, mixing, pressing, drying and sintering.
Application
Advantage
Fused cast AZS (alumina, zirconia and silica) firebricks are mainly categorized into 33#, 36# and 41# according to different zirconia's contents from 33% to 41%.
Fused cast alumina (α-β Al2O3 and β Al2O3) firebricks are composed of alpha alumina, beta alumina and small amount of glass phase.
Both AZS and alumina firebricks have shown excellent performance in glass furnace construction.
