Comprehensive Benefits: Provide efficient, stable, and high-quality technical support for metal melting and refining processes, creating significant economic benefits.

Main Application Fields

Industry Coverage: Widely used in four core industries: metallurgy, foundry, machinery, and chemical engineering.
Metallurgy Field: Provide a stable high-temperature environment for metal smelting and refining, achieving precise purity control.
Foundry Industry: Serve as a key tool for high-quality metal melting, directly ensuring casting quality.
Machinery Processing: Assist in the processing and treatment of metal materials to meet production needs.
Chemical Industry: Suitable for specific high-temperature reactions and material treatment processes.
Key Scenarios: Crucial in precious metal (gold, silver) processing and high-grade non-ferrous alloy production, as these fields have extremely high purity requirements.

Excellent Performance Advantages

High Efficiency & Energy Saving: Combined with high thermal conductivity and dense low-porosity structure, it shortens melting time and significantly reduces energy consumption.
Extended Service Life: Service life is 3-5 times that of ordinary clay graphite crucibles, reducing replacement frequency and costs.
Thermal Shock Resistance: Can withstand rapid temperature changes without cracking, ensuring safe use.
Strong Oxidation Resistance: Oxidation resistance is 5-10 times that of standard graphite crucibles, extending the service cycle.
Corrosion Resistance: Fine matrix design effectively slows down the corrosion rate of molten liquid on the crucible.
Reduced Loss: Little metal adhesion and slag buildup on the inner wall, maintaining stable crucible capacity and reducing cracking risks.
Purity Assurance: Strict material composition control ensures no contamination of metals during melting.

Specification

Available specifications: 1#, 2#, …, 30#, 40#, 80#, 150#, 200# – 3000#. Special requirements can also be customized.

Key Notes

Terminology Correction: "Apparent Porosity" is used for accuracy in technical expression.
Grammar Fix: Plural subjects (e.g., requirements) are paired with plural verbs (e.g., are), and "manufacture" is adopted for industrial context.
Symbol Uniformity: "–" is used in specifications to align with international notation standards.
