High alumina bricks for reverberatory furnace
Al₂O₃ (%)≥80~85; Fe₂O₃ (%)≤2.0~1.8Cold crushing strength(MPa): 65~70Refractoriness under load 0.2MPa(℃): 1530~1550
High alumina bricks for aluminum smelting reverberatory furnace, which Al₂O₃ content is 80%~85%, are used as linings of the part where it is exposed to aluminium liquid.
