Magnesia chrome bricks are 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 good thermal spalling resistance. The low–basic neutral nature gives itself good slag resistance when servicing low–acid feed furnaces. Magnesia chrome bricks are a realistic lining material for refining furnaces, electric furnaces, glass melting furnaces and cement rotary kilns, etc.
High refractoriness: can withstand temperatures up to 1750 °C
Excellent thermal shock resistance: can withstand rapid temperature changes without cracking or breaking
Good chemical stability: resistant to attack from most acids and alkalis
High strength: strong enough to withstand heavy loads and wear and tear
Good insulation properties: help to maintain consistent temperatures in high-temperature environments
Used in the lining of furnaces and kilns in various industries such as steel, glass, cement, and petrochemical.
Also used in the manufacturing of ceramics, non-ferrous metals, and other refractory materials.
Can be used in the construction of high-temperature equipment such as heat exchangers, boilers, and incinerators.
It finds its application in the field of nuclear power plants, aerospace, and defense as well.
