Product Description

Description of Magnesia Alumina Spinel Fire Brick:
Magnesia Alumina Spinel Fire Brick are a high-performance alkaline refractory material widely used in high-temperature industrial environments, such as cement rotary kilns, non-ferrous metallurgy, lime kilns, glass industry and other fields that need to withstand extreme temperatures and chemical erosion. Here are some key features and introduction of Magnesia Alumina Spinel Fire Brick:

9-12% Al2O3 Content High Temperature Pressing Magnesia Alumina Spinel Fire Brick for Cement Industry 0
Main Components of Magnesia Alumina Spinel Fire Brick
Periclite (MgO): Provides the basic framework and high temperature resistance of the brick body.
Magnesium Aluminate Spinel (MgAl2O4): Is a stable solid solution that improves the brick's resistance to chemical attack and thermal shock stability.

Characteristics of Magnesium Aluminum Spinel brick
High Strength: Through high pressure forming and high temperature sintering, magnesium aluminum spinel bricks have obtained high mechanical strength and can withstand heavy loads and wear.
Thermal Shock Stability: Due to the difference in thermal expansion coefficients of its components, tiny pores are formed inside the brick body, which helps to absorb thermal stress and reduce damage caused by sudden temperature changes.
Resistance to Chemical Attack: The spinel structure can resist the erosion of acidic and some alkaline substances, especially suitable for areas in contact with clinker in cement kilns.
Low Porosity: Reduces the permeability of the material and improves the density and durability of the overall structure.
Long Life: In the transition zone and firing zone of the cement rotary kiln, magnesium aluminum spinel bricks can be consumed synchronously with the materials in the kiln, extending the overall service life of the kiln lining.
