Magnesia Carbon &
Alumina Magnesia Carbon Refractory Bricks

• Exceptional Thermal Stability: Operates reliably at temperatures exceeding 1750℃ (3182℉), ideal for molten steel environments.
• Superior Thermal Shock Resistance: Graphite content (10-14%) minimises cracking during rapid thermal cycling.
• Advanced Slag Corrosion Resistance: High-purity magnesia (MgO > 85%) and antioxidants resist aggressive basic slags and chemical attack.
• Optimised Thermal Conductivity: Low conductivity reduces heat loss, improving energy efficiency and maintaining stable process temperatures.
• High Mechanical Strength: Cold crushing strength (30-40 MPa for MgO-C; 55-60 MPa for AMC bricks) ensures durability under mechanical stresses.
• Tailored Formulations: Customisable carbon and additive content for specific applications such as slag lines or EAF hot spots.
• Enhanced Safety: Non-toxic, asbestos-free materials with stable performance reduce risks of refractory failure.
• Lower CO₂ Emissions: Optimised formulations and extended service life reduce refractory consumption, minimising CO₂ emissions from production and disposal.

• Extended Service Life: Advanced antioxidant systems (e.g., Al, Si, B₄C) reduce carbon oxidation, achieving up to 120+ heats in ladle slag lines and 50% longer EAF campaigns.
• Precision Manufacturing: High-pressure pressing (500 & 2000T) and automated batching ensure consistent density and microstructure.
• Customisable Solutions: Tailored brick compositions and shapes optimize performance for specific furnace conditions and steel grades.
• Reduced Downtime: Superior thermal shock resistance minimises spalling, lowering maintenance frequency and costs.
• Enhanced Safety Profile: Stable refractory performance reduces risks of sudden lining failures, protecting personnel and equipment.
• CO₂ Reduction: Up to 20% lower refractory consumption, reducing emissions by approximately 1525 Kg CO₂ per ton of refractory material.
• Sustainability Focus: Eco-friendly additives and energy-efficient processes minimise environmental impact while maintaining performance.

Our Magnesia Carbon Bricks are designed for high-performance refractory linings in:

• Steel Ladles: Slag lines, metal zones, and bottoms, providing superior resistance to slag penetration and thermal cycling.
• Electric Arc Furnaces (EAFs): Hot spots, slag lines, and tap holes, ensuring stability under high-temperature arcing and slag attack.
• Basic Oxygen Furnaces (BOFs): Sidewalls, bottoms, and charge pads, designed for aggressive slags and high mechanical stress.
• Specialized Applications: Secondary refining vessels (RH, VOD), non-ferrous smelting furnaces, and high-temperature industrial kilns.

Our state-of-the-art production facilities ensure consistent quality through:

• Advanced Equipment: High-capacity friction presses (500 & 2000T) and automated mixing systems for precise blending.
• High-Temperature Firing: Tunnel kilns operating at 1600–1800℃ ensure optimal sintering and structural integrity.
• Quality Assurance: Rigorous testing for chemical composition, porosity, strength, and thermal properties, compliant with ISO 9001:2015 and ISO 14001:2015 standards.
• R&D Innovation: Dedicated research team developing low-emission formulations and advanced oxidation-resistant additives.
