Magnesia-iron spinel bricks are made from magnesium, iron and other metal concentrates as the main raw materials, and are produced through processes such as beneficiation, crushing, mixing, pressing and sintering. This material has a series of excellent properties such as high temperature corrosion resistance, excellent thermal shock stability, excellent mechanical strength, low thermal expansion coefficient, and excellent fire resistance. It is an ideal choice in ammonia synthesis, coal gas production, boiler waste heat utilization and other industries. Indispensable high-end refractory materials.
"The biggest advantage of the refractory mafic spinel brick is its high temperature stability and high corrosion resistance. Magnesia spinel bricks will not cause thermal expansion, softening, cracking and other problems in high temperature environments, which can ensure the stability of the equipment performance and long-term safe operation; and it also resists corrosion well with chemicals, extending the service life of equipment lining materials.
Refractory mafic spinel bricks can be widely used as lining materials for the inner chambers of high-temperature kilns, smelting furnaces, converters and other equipment in the steel, cement, building materials and other industries.
In the chemical industry, mafic spinel bricks are widely used in important parts of ammonia synthesis plants, such as converters, high-pressure circulation condensers and absorption tower reactors. This is mainly due to the high temperature stability and corrosion resistance of mafic spinel bricks, which ensure the stable operation of equipment under high temperature and high pressure, thereby ensuring its production efficiency.
In the field of coal gas production, mafic spinel bricks are also widely used in important parts such as gas converters and coolers. This is also because the mafic spinel bricks have a low thermal expansion coefficient and are not easily deformed under high temperature and pressure, thus extending the service life of the equipment.
Compared with traditional refractory materials, mafic spinel bricks have excellent vehicle wear resistance, high-temperature mechanical properties and high-temperature stability, and have a significantly longer service life.
