Magnesia Refractory Series Products

Noral magnesia brick

Noral magnesia brick is made of Alumina Magnesia spinel, periclase. It has higher temperature strength, good thermal shock stability, strong resistance to basic slag.

Magnesia-Alumina spinel brick

Magnesia-Alumina spinel brick is made of Alumina-magnisia spinel, fused magnesia clinker and high purity magnesia clinker at high-pressure, sintered at temperature over 1700℃. It has the advantage of excellent qbrasive-resistance strength, good resistance to reducing at mospheres and free CO2、SO2、SO3、K2O、Na2O. It is mainly used in lining of lime rotary kiln of steel mill, the top of furnace.
