Advantages of Magnesia Brick
Refractory Performance
Refractory magnesia bricks can withstand extremely high temperatures, often reaching over 1500 degrees Celsius. Magnesia brick is an excellent refractory material that can withstand high temperature environments without losing its structural strength.
Excellent Slag Resistance
Magnesia bricks are alkaline refractory bricks that have strong resistance to alkaline slags, and are often used as masonry materials for alkaline kilns. Magnesia bricks have high strength and hardness and can withstand greater pressure and load.
Gute Wärmeleitfähigkeit
Refractory magnesia bricks have high thermal conductivity and can absorb and release heat quickly. This makes it very effective in applications where rapid heat transfer is required, such as high-temperature furnaces, kilns, etc.
Long Life and Durability
Magnesia refractory bricks have a long service life due to their resistance to high temperature and chemical attack. It is not easily damaged and degraded, and can stably assume the function of a fire-resistant structure for a long time
Thermal Expansion Adaptability
The linear expansion coefficient of magnesia bricks increases with temperature. In high-temperature environments, it can quickly conduct and dissipate heat, prevent the accumulation of thermal stress, and reduce the risk of structural damage.
Leichtes Material
Compared with other refractory materials, magnesia bricks have lower density and lighter weight. This makes it useful in some situations where structural load needs to be reduced, and also facilitates the construction and transportation process.
