Magnesia bricks for ladle
MgO (%)≥92; SiO₂ (%) ≤1.20; CaO (%)≤2; Fe₂O₃ (%)≤1.2Bulk Density(g/cm³)≥2.90; Apparent Porosity(%)≤160.2mpa Refractoriness under load T0.6 (℃)≥1530
As the ladle refractories, magnesia bricks or burnt magnesite bricks are mainly used as permanent linings because of high temperature property and high slag resistance.
