China Normal Standard Nonferrous Smelting Furnace Cement Rotary Kiln MGO Chrome Refractory Brick, Find details about China Chrome Magnesite Bricks, Magnesite Chrome Refractory Brick from Normal Standard Nonferrous Smelting Furnace Cement Rotary Kiln MGO Chrome Refractory 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.
