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.

Product Advantages

1. 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.

2. Energy Efficiency

- Significant energy-saving properties, lowering operational costs for clients.

3. Cost-Effectiveness

- Reduces production costs for non-ferrous metal smelting enterprises while improving productivity.

4. Advanced Manufacturing Process

- Produced via static pressing technology, ensuring consistency and structural integrity.

Manufacturing Process

1.Raw Material Blending: High-purity SiC powder and flake graphite are 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) are applied for extended lifespan

Primary Applications

1. Non-Ferrous Metal Casting

- Aluminum/Copper Alloys: Used in automotive parts (e.g., engine blocks, radiators) and electrical component production.

- Precious Metals: Gold/silver refining and jewelry casting requiring contamination-free melting.

2. Recycling Facilities

- Efficient recovery of scrap metals (e.g., zinc, lead) with minimal material loss.

3. Die-Casting Operations

- High-volume production of complex geometries in zinc/aluminum die-casting systems.

4. Research Laboratories

- Small-capacity crucibles (<5kg) for R&D in advanced alloy development.
