Magnesia-aluminum spinel brick is a high-temperature refractory material that is usually used in high-temperature environments such as industrial furnaces, such as furnace hearths, furnace walls and other components that need to resist high-temperature corrosion. Magnesia-aluminum spinel bricks are composed of magnesium oxide (MgO) and aluminum oxide (Al2O3). They have high thermal and chemical stability and can withstand extremely high temperatures and chemical attack.
High temperature resistance: able to withstand high temperatures up to 1700 degrees Celsius.
Corrosion resistance: able to resist the erosion of acids, alkalis and other corrosive substances.
Excellent thermal shock stability: It has a low thermal expansion coefficient and can maintain structural integrity under conditions of rapid temperature changes.
Good insulation performance: It has good insulation performance and is suitable for applications such as electric furnaces that require insulation materials.
High strength and hardness: It has high mechanical strength and hardness and can withstand certain mechanical stress.
Magnesia-alumina spinel bricks are widely used in metallurgy, chemical industry, electric power and other industries. They are often used in the lining of high-temperature furnaces, glass kilns, steel smelting furnaces, aluminum electrolytic cells and other equipment to provide fire resistance and thermal insulation protection.
In addition, they can be used in petroleum refining, chemical reactors and other industrial equipment that require resistance to corrosion and high temperatures。Especially in Cement industry, magnesia aluminum spinel brick provides a new furnace lining concept for cement rotary kilns. Its good structural flexibility and excellent kiln skin hanging performance make it Provides high adaptability. In recent years magnesia-aluminum spinel bricks have been fully used in the high-temperature zone of cement rotary kilns.
