High-Performance Refractories for Secondary Aluminium Processing
Vulcan Refractories offers a specialised range of refractory linings and components engineered for the demanding conditions of secondary aluminium production. Designed for use in melting, reverberatory, and holding furnaces, our solutions provide durability, thermal resistance, and corrosion protection, supporting efficient processing of recycled aluminium and alloying operations in cast houses.
Applications in Secondary Aluminium Furnaces
Our refractory products are used across all major furnace zones and components in aluminium processing, including:
- Melting furnaces: Handling high-temperature metal recovery
- Reverberatory furnaces: Where even heat distribution and erosion resistance are key
- Holding furnaces: Requiring chemical stability and thermal efficiency
These linings are ideal for the melting of recycled aluminium and alloy blending in industrial cast houses.
Key Performance Characteristics
Vulcan’s refractories are built to withstand the harsh chemical and thermal environments of aluminium furnaces:
- High-temperature resistance – Withstands temperatures above 1100°C
- Erosion and wear resistance – Ideal for high-impact zones, such as tap-outs and impact blocks
- Resistance to alkali salts – Protects against corrosive slags and fluxes
- Corundum formation resistance – Ensures long-term lining integrity and operational efficiency
Specialist Refractory Products
Vulcan supplies a comprehensive range of materials and shapes tailored for secondary aluminium applications:
- Phosphate-bonded 84% alumina bricks: For long-lasting furnace linings
- Nitride-bonded silicon carbide blocks: Tap-out and impact blocks for high-wear zones
- Silicon carbide components: including stopper rods, pump liners, and launders for molten metal handling
- Alumina and silicon carbide cements: For repairs and installation of refractory linings
These products are engineered to maintain structural integrity and thermal performance throughout the aluminium melting and holding process.
