Description
Types of Magnesia Carbon Bricks :
Magnesia Carbon Bricks
Magnesia Carbon Brick is a resin-bonded brick produced from dead-burned or fused magnesia and graphite. Anti-oxidant is also added if needed. Magnesia-Carbon brick works well in thermal resistance, corrosion, resistance, and spalling resistance.
Where it is used ?
Magnesia Carbon Brick is used in converters, EAFs ( Electric Arc Furnaces ), ladles and refining furnaces
Magnesia-Alumina Carbon Brick or Alumina-Magnesia Carbon Brick
Magnesia-Alumina Carbon Brick or Alumina-Magnesia Carbon Brick is produced from high quality bauxite, corundum, fused magnesia and graphite. Alumina-Magnesia Carbon brick has proper residual expansion, low thermal conductivity, and better insulation performance than that of Magnesia-Alumina Carbon brick which contain much more magnesia.
Where it is used ?
It is used in the slag line of the ladle, lower part of the ladle wall, ladle bottom and free zone of the ladle.
Magnesia-Calcium Carbon Brick
Magnesia-Calcium Carbon Brick is produced from good quality magnesia, dolomite clinker and synthetic magnesia dolomite clinker. It is a good resistant of slag and has a good stability in high-temperature vacuum working environment and can also purify the liquid steel
