Vertical Tube Furnace

Introduction of Vertical Tube Furnace

Depending on the temperature, the furnace tube is made of high-purity quartz or alumina and equipped with a vacuum-sealing flange system. It is mainly suitable for pre-sintering, sintering, coating, and heating materials in vacuum or protective atmospheres at various temperatures. Solution to low-temperature deposition (CVD) process, preparation of carbon nanotubes and silicon nanowires, etc.

Features of Vertical Tube Furnace

• Maximum temperature: 1200 ℃ ( HRE resistance wire heating)
• 1400 ℃ (silicon carbon rod heating)
• 1600 ℃ (silicon molybdenum rod heating)
• Intelligent 50-segment programmable automatic control.
• Furnace shell structure, double-layer air-cooling structure.
• Stainless steel double-layer sealing flange.
• Adjustable flange support structures at both ends extend the service life of the furnace tube.
• Over-temperature protection function automatically cuts off power when the temperature exceeds the allowed set value.
• Safety protection: Automatically cut off power when the furnace body leaks electricity.
