JUCOS Refractories > Shaped Refractories > Magnesia Chrome Brick
Product Details

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.
