Product Description
Refractory Magnesia Chromium Bricks Heat Strength Rebonded 58% MGO Magnesite Chrome Brick
Magnesia Chrome Brick are direct-bonded and made from high grade magnesite clinker and chrome oxide. By high pressure shaping and high temperature firing, its characteristic is the high direct-bonding rate, and big crystallite. It has a good thermal spalling resistance. The low-basic neutral nature gives itself a good slag resistance when servicing low-acid feed furnaces.
The fused-rebonded brick are made of fused mgo chrome clinker,its a realistic lining material for refining furnace, electric furnace, glass melting furnace,AOD COD RH etc.
FeaturesOf Magnesia Chrome Brick
- Good thermal shock resistance performance
- Excellent resistance in slag abrasion
