Silicon Carbide Graphite Crucible for Non-Ferrous Metal Melting

Induction Furnace Crucible specifically optimized for high-temperature melting of non-ferrous metals in induction furnace environments. Crafted from a proprietary composite of silicon carbide (SiC)-bonded graphite, it delivers exceptional performance when processing metals including aluminum, copper, brass, bronze, zinc, and precious alloys (gold, silver, platinum). The innovative SiC-graphite matrix combines complementary properties: graphite provides outstanding thermal conductivity and thermal shock resistance, while silicon carbide contributes extreme hardness, oxidation resistance, and structural integrity at sustained temperatures exceeding 1600°C.

• Superior Thermal Management: Achieves rapid heating rates through optimized electromagnetic coupling with induction coils, significantly reducing melting cycles and energy consumption.
• Extended Service Life: Silicon carbide bonding creates a protective ceramic barrier that dramatically reduces graphite oxidation and withstands corrosive molten metals/slags, outperforming traditional clay-graphite crucibles by 2-3x.
• Critical Thermal Shock Resistance: Engineered microstructure absorbs severe thermal stresses during rapid startup, pouring, and cooling cycles without cracking - essential for induction furnace operations.
• High-Temperature Structural Stability: Maintains dimensional integrity and mechanical strength at continuous operating temperatures up to 1600°C, even under heavy metal loads.
• Contamination-Free Melting: Chemically inert construction preserves melt purity for sensitive applications like aerospace alloys and jewelry casting.

• Core Technology: Silicon Carbide Graphite Crucible for coreless induction furnaces.
• Target Metals: Non-ferrous metals and alloys (Al, Cu, Zn, precious metals).
• Key User Groups: Foundries, Casting Shops, Recyclers, Jewelers/Refiners.
• Group-Specific Benefits:
  • Foundries: Thermal shock resistance, long life, high-volume efficiency.
  • Casting Shops: Durability, chemical resistance, repeated cycles.
  • Recyclers: Erosion resistance, handling impure scrap, efficiency.
  • Jewelers/Refiners: Thermal conductivity, minimal contamination, oxidation resistance, purity.
• Universal Benefits: Longer service life, reduced downtime, improved energy efficiency, consistent performance in demanding environments.
