Magnesia bricks for lead blast furnace
MgO (%)≥92; SiO₂ (%) ≤1.20; CaO (%)≤2; Fe₂O₃ (%)≤1.2Bulk Density(g/cm³)≥2.90; Apparent Porosity(%)≤150.2mpa Refractoriness under load T0.6 (℃)≥1530
Magnesia bricks can be used as lead blast furnace refractories for slag spout or hearth linings because of good slag and erosion resistance.
