Features

Fusion of Magnesia Strength and Carbon Resilience

By blending dense MgO with 10–20% graphite, each high quality magnesia carbon brick ensures optimal slag resistance and thermal flexibility. This structure protects linings against erosion, spalling, and sudden thermal shifts.

Oxidation Control with Advanced Anti-Oxidants

Every customized magnesia carbon brick formulation is enriched with anti-oxidants such as aluminum, silicon, and boron, extending service life under oxygen-rich, high-heat conditions.

Low Porosity, High Performance

Laurel’s magnesia carbon brick refractories have ≤5% apparent porosity, effectively blocking slag infiltration and maintaining structural integrity during continuous casting and secondary refining.

Tailored Engineering for Specific Zones

We provide customized magnesia carbon brick solutions for different parts of the furnace—impact pads, ladle slag lines, tapping channels—ensuring material efficiency and enhanced furnace performance.
