Silicon Carbide Graphite Copper Melting Crucible for Industrial Use

The Silicon Carbide Graphite (SiC Graphite) Crucible stands as the premier refractory vessel solution meticulously engineered to meet the extreme demands of copper melting, alloying, holding, and refining processes. Unlike standard refractories, this advanced composite crucible is specifically formulated to overcome the unique challenges posed by molten copper and its alloys - including high operational temperatures (exceeding 1085°C / 1985°F), aggressive slag formation, high fluidity leading to penetration risks, and the need for precise thermal management.

• Unmatched Thermal Resilience: Withstands sustained temperatures <1600°C and severe thermal cycling inherent in batch melting without cracking or spalling, ensuring operational reliability and crucible longevity.
• Enhanced Mechanical Robustness: High structural integrity resists mechanical stress from heavy copper charges, vigorous stirring for degassing or fluxing, and impact during handling. SiC's hardness drastically reduces erosion from scrap.
• Exceptional Chemical Inertness: Highly resistant to oxidation (crucial in air-containing furnace atmospheres) and corrosion from molten copper, copper oxides (CuO, Cu₂O), common refining fluxes (e.g., borax, soda ash), and slag.
• Optimized Thermal Conductivity: The SiC-Graphite synergy enables rapid, uniform heat distribution throughout the crucible wall. This translates to faster melting cycles, improved energy efficiency, and precise temperature control essential for consistent alloying and casting quality.

Qingdao Baidun's SiC Graphite Crucibles deliver uncompromised performance in high-purity copper processing - where crucible failure risks catastrophic contamination. Engineered for extreme thermal cycling and aggressive metallurgical environments.

They can be used for resistance furnace, induction furnace, biological particles furnace, gas furnace, coke oven, furnace oil, and gas furnace to melt gold, silver, copper, aluminum, tin, lead, zinc and other nonferrous metals, and various non-ferrous alloys.

• Copper: OFC, bronze, brass melting
• Aluminum: Alloy production, recycling
• Precious Metals: Gold, silver refining
• Specialty Processes: Vacuum melting, induction furnaces
