Our Customized Magnesia Carbon Bricks are engineered to meet the precise needs of industrial furnaces operating under extreme conditions. Combining high-purity magnesia (MgO) with carbon additives, these bricks deliver outstanding resistance to thermal shock, slag corrosion, and mechanical wear, making them ideal for steelmaking, non-ferrous metallurgy, and other high-temperature applications.
We offer flexible customization options in size, shape, and formulation to perfectly fit unique furnace designs, ensuring optimal lining performance and extended service life. The dense microstructure and low porosity reduce slag infiltration, enhance heat conductivity, and improve energy efficiency.

Production Details
Our Customized Magnesia Carbon Bricks are manufactured using high-quality raw materials, primarily premium-grade magnesia (MgO) and carbon additives, which ensure excellent resistance to slag corrosion, thermal shock, and mechanical wear. The production process involves:
Raw Material Selection: Carefully sourced to guarantee purity and consistent quality of MgO and carbon components.
Mixing & Forming: Precise proportions of magnesia and carbon are mixed, followed by shaping through advanced pressing or extrusion methods to achieve uniform density and structural integrity.
Firing & Graphitization: The shaped bricks undergo high-temperature firing and graphitization processes to enhance bonding strength and thermal stability.
Quality Control: Rigorous inspections at each stage, including chemical composition testing, physical property measurements, and visual checks to ensure bricks meet or exceed industrial standards.
Customization: We tailor brick sizes, shapes, and carbon content according to client specifications, optimizing performance for specific furnace environments.
Packing and Shipping Details
Packaging:
Each batch of magnesia carbon bricks is carefully packed on fumigation-free wooden pallets or in sturdy crates. The bricks are securely stacked and wrapped with waterproof film to protect against moisture and dust during transit. Steel straps reinforce the packaging to prevent shifting or damage.Shipping Methods:
We offer flexible shipping options tailored to customer needs, including sea freight, air freight, and express courier services. Shipping routes and logistics are optimized to ensure timely and safe delivery worldwide.
