High alumina bricks for rotary kiln
Al₂O₃ (%)≥48~85; Fe₂O₃ (%)≥1.8~2.5Cold crushing strength(MPa):45~70Refractoriness under load 0.2MPa℃≥1420~1550
High alumina bricks as rotary kiln refractories are mainly used for linings of burning zone in alumina production process, because of good corrosion and erosion resistance.
