Bottom Loading Furnace

The Bottom Loading Furnace is a sophisticated thermal processing system featuring an electrically operated elevator hearth. This unique design allows for the gentle, precise, and controlled loading of heavy or delicate samples into the high-temperature chamber from below. This configuration ensures minimal heat loss during loading, leading to exceptional temperature stability and uniformity throughout the process.

  • Exceptional Temperature Uniformity: With heating elements on all four sides of the chamber and high-grade insulation, the furnace provides a consistent and uniform thermal environment. This is crucial for applications like sintering and annealing, where even heating is vital for repeatable results.
  • Safe & Ergonomic Operation: The motorized lift table eliminates the need for manual handling of samples, which is particularly beneficial for heavy or delicate materials. This design improves user safety by keeping the operator away from the hot chamber, and it makes loading and unloading simple and precise.
  • High-Performance Heating Elements: The furnace utilizes advanced heating elements, either Silicon Carbide (SiC) for temperatures up to 1600°C or Molybdenum Disilicide () for higher temperatures up to 1800°C and beyond. These elements are chosen for their fast response, durability, and ability to operate in demanding environments.
  • Versatile and Programmable Control: The integrated programmable control system, often with a touchscreen interface, allows for the creation of multi-step thermal profiles (ramp-and-soak). This level of control is essential for complex processes like crystal growth and allows for precise and repeatable results.
  • Flexible Atmosphere Control: The furnace is designed to be protective atmosphere ready, with optional gas inlet ports for use with inert or reactive gases like nitrogen, argon, or forming gas. This protects sensitive materials from oxidation during high-temperature processing.

The Bottom Loading Furnace is a versatile tool used in both research and industrial settings for various high-temperature applications.

  • Powder Metallurgy and Sintering: Densifying metal and ceramic powders into solid forms.

  • Ceramic and Glass Firing: Precisely firing advanced technical ceramics and specialized glass.

  • Advanced Materials Testing: Conducting material property tests under extreme thermal conditions.

  • Crystal Growth and Zone Refining: Creating single-crystal materials for electronics and optics with high purity.

  • Annealing: Heat treating metals and alloys to improve their properties and reduce internal stress.

  • Max Temperature: Available in models with max temperatures of 1200°C, 1400°C, 1600°C, and 1800°C.

  • Heating Elements: SiC (for lower ranges) and (for higher ranges).

  • Temperature Control: Programmable PID controller with multi-step profiles.

  • Chamber: High-grade ceramic fiber insulation for superior thermal efficiency.

  • Lifting Mechanism: Electrically operated lift table with smooth, controlled movement.

  • Safety Features: Over-temperature protection, safety interlocks that cut power when the hearth is lowered, and a double-walled design with air cooling to ensure a cool-to-the-touch exterior.

  • Power: Available in various configurations (e.g., 220V, 380V, single-phase, or three-phase) to meet user requirements.
