Magnesia bricks for converters

MgO (%)≥92; SiO₂ (%) ≤1.20; CaO (%)≤2; Fe₂O₃ (%)≤1.2
Bulk Density(g/cm³)≥2.90; Apparent Porosity(%)≤16
0.2mpa Refractoriness under load T0.6 (℃)≥1530

Application:

As the converters steelmaking refractories, Magnesia bricks or burnt magnesite bricks are mainly used as permanent lining because of high temperature property and high slag resistance.

　　Magnesia bricks for steel converters use sintered magnesite or fused magnesia as main raw materials, being high pressure pressed and sintered in high temperature.
