High alumina bricks

Al₂O₃ (%)≥48~85; Fe₂O₃ (%)≥1.8~2.5
Cold crushing strength(MPa): 45~70;
Refractoriness(℃): 1760~1790; Refractoriness under load 0.2MPa(℃): 1420~1550

Application:

High alumina bricks are mainly used as the lining of blast furnace, hot air stoves, EAF roof, ladle, reverberatory furnace, rotary kiln. Furthermore, high alumina refractory bricks are also applied in regenerator of open-hearth furnace as checker bricks, stoppers and nozzle bricks as continuous casting system.
