Can a rotating inclined tube high-temperature furnace be evacuated?

The rotating inclined tube high-temperature furnace can be evacuated, and its vacuum function is achieved through an external vacuum pump, which can create a highly stable vacuum environment, effectively eliminate air and impurities, prevent material oxidation at high temperatures, and ensure material purity. The following is a detailed introduction to its vacuum function and related design:

Vacuum function design
Vacuum pump system: The rotating inclined tube high-temperature furnace can be connected to an external vacuum pump, and the vacuum system composed of the vacuum pump extracts gas from the furnace to form a vacuum environment. For example, by using a three-stage Roots pump group in conjunction with a molecular pump, the vacuum degree in the furnace chamber can be stably maintained below 5 × 10 ⁻ ³ Pa within 30 minutes, providing an oxygen free sintering environment for highly active materials such as silicon carbide and aluminum nitride.
Vacuum degree control: The rotating inclined tube high-temperature furnace can accurately control the vacuum degree, meeting the requirements of different materials and processes for vacuum degree. For example, in the annealing process of certain semiconductor materials, a specific high vacuum environment (such as 10 ⁻³ -10 ⁻³ Pa) is required to reduce the introduction of impurities and ensure the electrical properties of the material.

Advantages of vacuum function
Preventing material oxidation: Vacuum environment can effectively eliminate air and impurities, prevent adverse reactions between materials and oxygen in the air at high temperatures, and ensure the purity of materials.
Improving material quality: Heat treatment in a vacuum environment can avoid oxidation and contamination of materials at high temperatures, and improve the density and quality of materials.
Expanding application scope: The vacuum function enables the rotating inclined tube high-temperature furnace to be suitable for more material processing processes with special requirements for atmospheric environment, such as oxygen free sintering of highly active materials.

Related design features
Sealing system: High precision sealing flanges and rings are used to ensure a tight connection between the furnace tube and the furnace body, preventing gas leakage. Meanwhile, equipped with magnetic fluid sealing technology, the vacuum degree can also be ensured during the rotation process.
Atmosphere control: In addition to the vacuum environment, the rotating inclined tube high-temperature furnace can also be filled with various atmosphere gases, such as inert gases (argon, nitrogen), reducing gases (hydrogen), etc., and can accurately control the flow rate and pressure of gases. This is very important for materials that require heat treatment in a specific atmosphere.
Tilt rotation design: The tilt rotation design allows materials to be uniformly heated in the furnace, avoiding material accumulation and agglomeration. By adjusting the tilt angle and rotation speed, the residence time and movement trajectory of the material in the furnace can be controlled, thereby optimizing the sintering process parameters and improving the consistency of product quality.
