WHY CHOOSE US

Material:

Our Cylindrical Crucible is crafted from isostatically pressed silicon carbide graphite, a material that offers exceptional high-temperature resistance and excellent thermal conductivity, making it an essential tool for industrial smelting applications.

  1. Silicon Carbide (SiC): Silicon carbide is known for its extreme hardness and excellent resistance to wear and corrosion. It can withstand high-temperature chemical reactions, offering superior stability even under thermal stress, which reduces the risk of cracking during sudden temperature changes.
  2. Natural Graphite: Natural graphite delivers exceptional thermal conductivity, ensuring rapid and uniform heat distribution throughout the crucible. Unlike traditional clay-based graphite crucibles, our cylindrical crucible uses high-purity natural graphite, which improves heat transfer efficiency and reduces energy consumption.
  3. Isostatic Pressing Technology: The crucible is formed using advanced isostatic pressing, ensuring uniform density with no internal or external defects. This technology enhances the strength and crack resistance of the crucible, extending its durability in high-temperature environments.

 

Performance:

  1. Superior Thermal Conductivity: The Cylindrical Crucible is made from high thermal conductivity materials that allow for rapid and even heat distribution. This enhances the efficiency of the smelting process while reducing energy consumption. Compared to conventional crucibles, thermal conductivity is improved by 15%-20%, leading to significant fuel savings and faster production cycles.
  2. Excellent Corrosion Resistance: Our silicon carbide graphite crucibles are highly resistant to the corrosive effects of molten metals and chemicals, ensuring the stability and longevity of the crucible during prolonged use. This makes them ideal for smelting aluminum, copper, and various metal alloys, reducing maintenance and replacement frequency.
