General Information of Magnesite Chrome Brick for Furnace

 

Burnt magnesia-chrome bricks are made from high quality mag-nesia and chrome concentrate, cr2o3 content can be adjusted accord ing to different requirements. The bricks have good thermal stability and high temperature performance, and are widely used in cement kilns and non-ferrous rnetal metallur-gical furnaces and so on. High temperature burnt directly bonded magnesia-chrome bricks, semi-rebonded magne-sia-chrome bricks and rebonded magnesia-chrome bricks are made from low impurity raw materials. All or part of raw ma-terials are preburnt or electro fused. The best proportioning, high pressure moulding, ultra high temperature and good vol-ume stability. The bricks are widely used in large cement ro-tary kiln, and secondary refining units such as RH, VOD, AOD furnaces, non-ferrous metal met-allurgical furnaces, glass tanks and so on.

 

Direct-bonded magnesia chrome brick is made of low impurity chrome ore and high purity magnesia and sintered at high temperature over 1700℃.

Semi-rebonded and rebonded magnesia chrome bricks are made partially or fully of synthetic fused clinkers. They are shaped under high pressure and sintered at very high temperature.
