What should be noted when choosing a rotary tube furnace?

As a commonly used heat treatment equipment in laboratories, rotary tube furnaces have many advantages. They are mainly used for laboratory calcination and drying of battery positive and negative electrode materials, non strong acidic and alkaline powder materials, and granular materials. They are highly favored by research institutions, university laboratories, industrial and mining enterprise experimental testing institutions, etc. Let’s take a look at the aspects that need to be paid attention to when choosing a rotary tube furnace!

Temperature range:
The working temperature is one of the key factors in choosing a tube furnace. The temperature range of a rotary tube furnace can range from several hundred degrees Celsius to several thousand degrees Celsius, depending on the type of heating element and the material of the furnace tube. Common operating temperatures generally include temperature ranges of 200-1000 ℃, 1000-1200 ℃, 1200-1400 ℃, and 1400-1700 ℃. Choosing different furnace tube materials for these temperature ranges can ensure higher efficiency.
It is necessary to specify the maximum and continuous operating temperatures required to ensure that the selected equipment can meet experimental or production needs.

Heating zone length:
The length of the heating zone determines temperature uniformity and heating efficiency. A longer heating zone can provide a more uniform temperature field, suitable for experiments and production processes that require high temperature uniformity.
Therefore, when choosing a rotary tube furnace, the length of the heating zone should be considered.

Temperature control accuracy:
Temperature control accuracy is one of the important indicators for measuring the performance of rotary tube furnaces. A high-precision temperature control system can ensure the temperature stability of experiments or production processes, and improve the reliability and reproducibility of experimental results.

Atmosphere control:
Many experiments and production processes require specific atmospheric conditions to be conducted. Therefore, it is important to choose a rotary tube furnace with good atmosphere control function.
Common atmosphere control functions include vacuum, inert gas protection, etc., which should be selected according to actual needs.

Furnace tube material:
The choice of furnace tube material directly affects the service life and performance of the rotary tube furnace.
According to different usage needs, materials that are resistant to high temperatures, corrosion, and oxidation can be selected, such as quartz, alumina, mullite, or high-temperature alloys.

Security performance:
Safety performance is an important factor that must be considered when choosing a rotary tube furnace.
Good equipment should have comprehensive safety protection functions, such as over temperature alarm, leakage protection, emergency shutdown, etc., to ensure the safety of operators and equipment.

Other considerations:
The diameter and length of the rotary tube furnace are also important factors affecting its processing capacity and applicability. When selecting, the appropriate pipe diameter and length should be determined according to actual needs.

In addition, factors such as equipment maintenance costs, after-sales service, and manufacturer reputation should also be considered.
