Magnesia Carbon (MgO-C) Bricks

MgO-C brick is a composite material based on MgO and C and bonded with high carbon containing pitch and resin, with some metallic powder as anti- oxidants to protect the carbon. (MgO-C) bricks are made by high pressure. These bricks show excellent resistance to thermal shock and slag corrosion at elevated temperatures. MgO-C bricks are used extensively in steel making processes especially in basic oxygen furnaces, electric arc furnaces, lining of steel ladles, etc. MgO-C bricks have dominated the slag line of ladles as they possess superior slag penetration resistance and excellent thermal shock resistance at elevated temperature because of the non- wetting properties of carbon (graphite) with slag, high thermal conductivity, low thermal expansion and high toughness.

Advantages

  • Good high temperature resistance
  • Strong anti-slag penetration resistance
  • Resistance to thermal shock
  • High Corrosion resistance to slag
  • Non-Wettability to molten slag
