Dual-Phase Magnesia–Graphite System

The magnesia component ensures superior refractoriness and slag resistance, while the carbon phase—using 12–18% natural graphite—adds thermal shock flexibility and lubrication under heat and pressure. This synergy is a cornerstone of high-efficiency magnesia carbon refractory bricks.

Anti-Oxidant Protection for Prolonged Use

Laurel’s magnesia carbon bricks are infused with metallic antioxidants like aluminum and silicon to reduce graphite oxidation, increasing durability even in oxygen-rich furnace atmospheres.

Ultra-Low Porosity

With apparent porosity ≤5%, our magnesia carbon bricks block slag infiltration, resist spalling, and offer superior wear resistance, critical for slag lines, taphole areas, and ladle walls.

Resilience Against Thermal and Mechanical Stress

In operations where both heat and physical load are extreme, such as electric arc furnaces (EAFs) or basic oxygen furnaces (BOFs), these magnesia carbon refractory bricks ensure longer campaign life and lower maintenance cycles.
