Anti-stripping high alumina bricks
Al₂O₃(%) ≥70; ZrO₂(%) ≥6.0; Fe₂O₃ (%) ≤1.5Cold crushing strength (MPa) ≥60Refractoriness under load 0.2MPa (℃) ≥1470
Anti-stripping high alumina bricks as frequently used cement kiln refractories are mainly used in precalciner, grate cooler, and these parts of cement rotary kiln, such as outlet zone ,inlet zone, transition zone, calcining zone and preheating zone.
