Tubular furnaces are versatile tools used in various processes that require precise and controlled heating of materials.
These furnaces are particularly useful for sintering small objects or materials, annealing, brazing, calcination, degassing, sintering, soldering, sublimation, synthesis, and tempering.
In laboratory settings, they are employed for thermocouple calibration, testing of fuel cells, and catalyst research.
What is the Use of Tubular Furnace? 7 Key Applications Explained
1. Sintering and Material Processing
Tubular furnaces are ideal for sintering small particle ore, glass powder, and ceramic powder.
Their design allows direct insertion of materials into the heated tube.
This direct heating facilitates uniform temperature distribution and rapid temperature changes, which are crucial for sintering processes.
2. Heating Elements and Atmosphere Control
These furnaces typically use silicon molybdenum rods as heating elements.
These elements are capable of producing high temperatures and are resistant to wear and corrosion.
The atmosphere inside a tubular furnace is often circulated, which is beneficial for processes that require exposure to specific environments, such as inert or reactive gases.
3. Versatility and Control
Tube furnaces are designed with features such as independent digital control modules, double-shell construction, variable density insulation, and split-hinge designs.
These features enhance their versatility and control.
They allow for horizontal or vertical usage and precise temperature control, making them suitable for a wide range of applications, including heating metal or technical ceramic samples in various atmospheres.
4. Industrial and Laboratory Applications
In industrial settings, tubular furnaces are valued for their ability to control temperatures up to 1800°C.
They offer short melting times, instant heating and cooling, and low volume of flue gases.
This makes them indispensable in processes such as annealing, brazing, calcining, ceramics, cleaning, crystal growth, firing, glass, gradient work, heat treating, laboratory research, materials testing, and melting.
5. Material and Insulation
The tubes of these furnaces are commonly made from materials like alumina, fused quartz, and Pyrex.
Tungsten or molybdenum is used for corrosive materials.
Effective insulation is used to minimize heat transfer to the environment, ensuring efficient operation and safety.
6. Precision and Control
Overall, the tubular furnace is a critical tool in both industrial and laboratory settings.
It offers precise and controlled heating capabilities that are essential for a wide array of material processing and research applications.
