The temperature of a tube furnace can vary significantly depending on the specific model and its design.
However, certain high-temperature models can reach up to 1800°C (3272°F).
For example, the "Three Zone High Temp Tube Furnace 1400°C" is designed to operate at a maximum temperature of 1400°C.
This makes it suitable for heat treatment of various materials, including metal, ceramic, nano, and semiconductor materials.
4 Key Factors to Consider
1. Type of Heating Element
The temperature capabilities of tube furnaces are largely influenced by the type of heating element used.
Furnaces equipped with Fe-Cr-Al or Ni-Cr-Al alloy heating elements can operate between 250 to 1250°C.
Those with SiC heating elements can operate between 1300 to 1600°C.
And those with MoSi2 heating elements can operate between 1600 to 1800°C.
The choice of the heating element directly determines the maximum and continuous working temperatures of the furnace.
2. Processing Tube Material
The selection of the processing tube material is crucial.
It must withstand the furnace's maximum operating temperature without undergoing unwanted chemical reactions.
For example, quartz tubes are suitable up to 1200°C in atmospheric conditions.
While alumina tubes can withstand up to 1800°C.
3. Maximum Operating Temperature
The maximum operating temperature of a tube furnace can be tailored to specific needs.
This is achieved by selecting the appropriate heating element and processing tube material.
This ensures optimal performance for various industrial and research applications.
4. Model and Design
Different models and designs of tube furnaces have varying temperature capabilities.
For instance, the "Three Zone High Temp Tube Furnace 1400°C" is designed for high-temperature applications.
While other models may be designed for lower temperature ranges.
