Features

Features

Synergistic Three-Phase Structure

Each magnesia aluminum carbon fire brick combines the resilience of alumina, the basicity of magnesia, and the flexibility of graphite to form a high-density refractory capable of withstanding complex slag chemistry and intense thermal cycling.

In-Situ Spinel Generation for Long-Term Performance

Magnesia and alumina react under operating conditions to create in-situ magnesium aluminate spinel, enhancing the magnesia alumina carbon refractory brick's strength, corrosion resistance, and service life in steel ladle linings.

Graphite-Fortified Thermal Shock Resistance

The inclusion of high-purity flake graphite enables magnesia aluminum carbon fire bricks to absorb thermal stress, reducing spalling and surface cracking in environments with frequent heating and cooling cycles.

Optimized for Steel Ladle Working Linings

Laurel’s magnesia aluminum carbon fire bricks are designed for areas such as ladle slag lines, where anti-erosion performance and thermal reliability are essential to production continuity.
