Large Graphite Crucibles for Industrial-Scale Melting & Casting
Heavy-Duty Crucibles Tailored for Demanding Applications
At SHJ-CARBON, we specialize in large graphite crucibles engineered to meet the extreme conditions of high-temperature industrial operations. With customizable height, bottom diameter, top diameter, and wall thickness, our crucibles are ideal for heavy-load applications such as metal melting, alloy refining, and continuous casting.
Available in barrel, cylindrical, and conical shapes, these crucibles are designed for compatibility with a wide range of furnaces and workflows. Despite their size, each crucible remains lightweight and easy to install, offering both handling convenience and structural strength.
Products Description
| Melting Capacity | Recommended Model | Typical Dimensions (Diameter × Height) |
| 10–50kg | #30–#100 | Φ205–345mm × H265–388mm |
| 50–200kg | #150–#400 | Φ362–526mm × H429–661mm |
| >200kg | #500 and above | ≥Φ531mm × ≥713mm |
| Customized | ≥Φ1650mm |
Key Notes:
Dimensional Tolerance: All sizes allow ±5% variation due to manufacturing processes.
Capacity Scaling:
Small models (e.g., #30) suit laboratory/precision melting;
#500+ models align with industrial furnaces (e.g., 500kg aluminum melters use Φ785mm crucibles).
Customization: Non-standard dimensions (e.g., rectangular, tapered) require bespoke design.
Note: Match crucible dimensions to furnace chamber geometry to ensure thermal efficiency
Built to Withstand Extreme Heat & Stress
Our large graphite crucibles are capable of withstanding temperatures up to 1800°C in oxidizing atmospheres and up to 3000°C in vacuum or inert conditions. Even under prolonged exposure to extreme heat, they maintain structural integrity and resist cracking, warping, or erosion.
These crucibles are suitable for melting aluminum, copper, gold, silver, brass, and other non-ferrous metals. They are also used in glass and ceramic processing, where thermal uniformity is essential for product quality.
Key Performance Advantages
- High Thermal Conductivity: Enables even heat distribution and faster melting cycles
- Oxidation & Wear Resistance: Minimizes degradation and extends product life
- Exceptional Thermal Shock Resistance: Handles rapid heating and cooling without damage
- Custom Engineering: Shape, size, and coating can be tailored for your furnace and material
- Lightweight & Easy to Handle: Designed for industrial use without added operational burden
