Moreover, these bricks are designed to withstand the harshest conditions and maintain their performance over an extended period. Therefore, this longevity translates to significant cost savings by reducing the frequency of brick replacements and associated downtime.
The combination of magnesia and carbon results in a refractory brick with superior mechanical strength, which enables it to withstand heavy loads, abrasion and mechanical stress. Additionally, it has good performance in stress and abrasion. Whether it’s in the steel industry or non-ferrous metallurgy, Kerui magnesia carbon bricks maintain the structural integrity, ensuring long-term performance and reliability.
How Are Magnesia Carbon Bricks Made?
The production of magnesia carbon brick doesn’t need sintering, which has shorter production cycle and can delivery quickly. Here is description of how are magnesia carbon bricks made:
Crush natural magnesia and other raw materials into specified size. The quality inspection department will check the appearance, size, color and chemical compositions. The superior raw material will be transported into fully automatic batching system.
Kerui advanced press machine can mold magnesia bricks with precise shape and size. Moreover, as the molding pressure increases, the strength, density and load softening temperature of this fire resistant brick for sale will also increase accordingly.
In the advanced heat treatment system, Kerui skillful workers will put magnesia bricks into high temperature kilns at 220℃ (428℉). Additionally, MgO and C with high purity react chemically at this temperature and form a compact structure.
Kerui SKILLFUL workers and quality inspection department will check the finished magnesia carbon bricks carefully. Moreover, Kerui staff will pack the high-quality magnesia carbon bricks will in strict accordance with customer requirements.
Uses of Kerui Magnesia Carbon Brick
Mainly Used for Steel-making Industry
Due to excellent characteristics, magnesia carbon fire brick is very suitable for iron and steel smelting. Carbon materials are not easily corroded by slag and molten steel. Besides, magnesia has high refractoriness, strong slag resistance and creep resistance and can well deal with slag lines and steel ports that are severely damaged by corrosion. Customers often use this brick in converters of steelmaking furnaces, electric arc furnaces, inner linings, ladle slag lines, refining furnaces and other parts.
Also Used for Other High Temperature Industries
In addition to the steel industry, magnesia carbon bricks has wide applications in other high-temperature kilns that are severely eroded by alkaline substances. Such as basic oxygen furnace lining, metallurgical furnace, cement furnace, working lining of ceramic furnace and other parts. Therefore, Kerui magnesia carbon refractory brick is suitable for all kinds of high temperature furnaces and kilns. Many customers choose the magnesium carbon brick for their business.
