China OEM China Insulation Refractory Brick - Refractory magnesia Chrome Brick For Furnace Lining – Rongsheng factory and manufacturers | Rongsheng Detail:

Magnesite chrome block uses quality magnesia and chromic oxide as the raw material, molded through high press and fired in the high temperature. magnesia chrome bricks have features of large crystal and high direct bonding rate. and magnesite chrome fire bricks have good cracking resistance and good acid slag erosion resistance with low alkaline property. magnesite chrome block is the ideal lining brick material for finery out of furnace, electric furnace, glass furnace, melting furnace and rotary cement kiln.

Properties of Magnesia Chrome Bricks

High flexibility,
Low thermal conductivity,
High temperature strength,
Good thermal shock resistance,
Strong furnace slag erosion resistance.
Classification of Magnesia Chrome Bricks

Due to the quality of magnesia chrome bricks, magnesia chrome brick is divided into ordinary magnesia chrome brick, direct bonded magnesia chrome brick, semi bonded magnesia chrome brick, rebonded magnesia chrome brick and so on.

Magnesia Chrome Bricks Manufacturing Process

Magnesia chrome bricks are made of bonded common sintered material, and eliminate loose effect caused of the expansion when producing the spinel by the reaction of MgO and Cr2O3, Al2O3 or FeO. Moreover, there is also unburned magnesite chrome fire brick such as unburned magnesite chrome block is made of inorganic magnesia saline solution. and unburned magnesia chrome brick is simple and low cost. this kind of magnesia chrome brick has great thermal stability, but its high temperature strength is lower than burnt magnesia chrome brick.
