WHY CHOOSE US

Our Crucibles for Furnace are crafted from high-quality materials specifically selected to enhance performance:

  • Graphite and Silicon Carbide Compositions: The combination of these materials offers excellent thermal conductivity, ensuring rapid and even heating. The inherent properties of graphite allow for high-temperature resistance, while silicon carbide contributes to superior durability and thermal shock resistance.
  • Accelerated Thermal Transmission: The adoption of high thermal conductivity materials furnishes the crucibles with a dense organization and reduced porosity, enhancing fast thermal transmission. This leads to quicker melting times and improved energy efficiency.

 

Superior Density and Design

The design of our furnace crucibles is tailored to meet the specific needs of various furnace types, allowing for enhanced efficiency and performance:

  • State-of-the-Art Isostatic Pressing: This advanced manufacturing technique achieves a uniform and faultless material with exceptional density. The result is a crucible that offers increased strength and durability during the melting process.
  • Elevated Resilience: Our crucibles are designed using high-pressure molding, superior raw materials, and professional product design. This results in an exceedingly sturdy material that can withstand elevated pressure levels, ensuring reliability in demanding applications.

 

Increased Lifespan

One of the significant advantages of our Crucibles for Furnace is their extended lifespan:

  • Longevity Compared to Regular Clay Graphite Crucibles: Our crucibles boast a lifespan that is prolonged by 2 to 5 times in comparison to standard clay graphite crucibles, depending on the material employed. This durability translates to fewer replacements and lower operational costs over time.

 

Graphite Crucible Temperature Range

Our furnace crucibles excel in their ability to withstand extreme temperatures:

  • Wide Temperature Range: Our graphite crucibles can operate effectively within a temperature range of up to 1700°C, making them suitable for a variety of applications, including ferrous and non-ferrous metal melting, as well as precious metals like gold and silver.
  • Thermal Shock Resistance: Designed to handle rapid temperature changes, our crucibles maintain their structural integrity, providing reliable performance in continuous melting operations.
