High Performance Elliptical SiC Graphite Crucible Optimized for Smelting Recycling

High-Performance Elliptical SiC-Graphite Crucible: Optimized for Smelting & Recycling

Integrating the synergistic properties of silicon carbide (SiC) and graphite, these advanced crucibles are purpose-built to optimize high-temperature metal processing in smelting, casting, and alloy production. The innovative incorporation of a precision-engineered pouring spout ensures controlled, laminar flow during molten metal transfer — minimizing oxidation risks, material waste, and operational downtime.

• Superior Material Performance
  • Anti-oxidation: Enhanced resistance to oxidation for prolonged durability
  • Excellent Thermal Conductivity: Efficient heat transfer to optimize smelting processes
  • Extended Service Life: Long-lasting performance, reducing replacement frequency
• Energy Efficiency: Significant energy-saving properties, lowering operational costs
• Cost-Effectiveness: Reduces production costs while improving productivity
• Advanced Manufacturing Process: Produced via static pressing technology for consistency and structural integrity

1. Raw Material Blending: High-purity SiC powder and flake graphite mixed with temporary binders
2. Isostatic Pressing: Uniform compaction under high pressure ensures structural homogeneity
3. High-Temperature Sintering: Fired at 2,000-2,300°C in inert atmospheres to form covalent SiC-graphite bonds
4. Surface Treatment: Anti-oxidation coatings (e.g., SiC glaze) applied for extended lifespan

• Non-Ferrous Metal Casting
  • Aluminum/Copper Alloys: Automotive parts (engine blocks, radiators) and electrical components
  • Precious Metals: Gold/silver refining and jewelry casting requiring contamination-free melting
• Recycling Facilities: Efficient recovery of scrap metals (zinc, lead) with minimal material loss
• Die-Casting Operations: High-volume production of complex geometries in zinc/aluminum systems
• Research Laboratories: Small-capacity crucibles (<5kg) for R&D in advanced alloy development
