Features of Magnesia Iron Spinel Refractory Brick

High Compressive Strength: Magnesia iron spinel bricks have a stable and flexible structure. So they have high compressive strength. The spinel of bricks helps to resist mechanical shock and friction. In this situation, they are good substances to replace magnesia chrome bricks.
Good Thermal Shock Resistance: The high refractoriness of magnesium iron spinel refractory brick is conducive to withstanding high-temperature equipment. In the rotary kilns, magnesia iron spinel brick can form a protective film to undertake the thermal shock. Moreover, the low refractoriness under load also helps to resist the thermal shock.
Environment Friendly: Magnesium iron spinel brick mainly consists of magnesia oxide, alumina oxide, and ferric oxide. And it will not react with other chemical substances in the high-temperature equipment. In this situation, magnesia iron spinel brick will not release poisonous gas.
Strong Resistance to Permeability: In a high-temperature environment, magnesia iron spinel bricks will form protective films to resist chemical erosion. The high bulk density also helps to improve the resistance to permeability. Strong resistance to permeability benefits reducing chemical erosion.

Applications of Magnesia Iron Spinel Bricks

Magnesium iron spinel bricks can replace magnesia chrome bricks that are used for cement rotary kilns. They can also used in ladles, lime vertical furnaces, heat treatment furnaces, recirculating fluidized bed furnaces, and other industrial furnaces.
