Compared to ordinary tube furnaces, customized rotary tube furnaces with multiple temperature zones

The customized rotary tube furnace with multiple temperature zones is significantly superior to ordinary tube furnaces in terms of temperature control, heating uniformity, process flexibility, intelligent operation, material applicability, and energy conservation and environmental protection. The specific advantages are as follows:

1. Temperature control: Independent temperature control in multiple temperature zones to meet complex process requirements
Ordinary tube furnace: usually designed with a single temperature zone, the entire furnace can only be set at a unified temperature, which is difficult to meet the needs of multi-stage heating or gradient temperature treatment.
Multi temperature zone customized rotary tube furnace: equipped with multiple independent heating zones, each temperature zone can be set separately (such as cracking raw materials in the high temperature zone in the front, promoting reactions in the medium temperature zone in the middle, and annealing stability in the low temperature zone in the back), with a temperature control accuracy of ± 1 ℃ and small temperature fluctuations. For example, in the preparation of lithium-ion battery materials, different temperature zones can achieve separate decomposition, sintering, and cooling of raw materials, avoiding the problem of multiple steps that cannot be taken into account in a single temperature zone, and improving material crystallinity and cycle life.

2. Heating uniformity: Rotating design eliminates temperature gradients
Ordinary tube furnace: Static heating can easily lead to uneven temperature distribution inside the furnace, and local overheating or undercooling may cause inconsistent material properties or process defects.
Customized rotating tube furnace with multiple temperature zones: The sample is continuously rolled inside the furnace tube through the rotation function, combined with gradient temperature control in multiple temperature zones to ensure uniform heat distribution. For example, in the preparation of fuel cell catalysts, the rotation function enables Pt/C catalyst powder to uniformly contact reducing gases (such as H ₂), improving the uniformity of catalyst active site distribution and increasing fuel cell efficiency by 10% -15%.

3. Process flexibility: adaptable to diverse experimental and production scenarios
Ordinary tube furnace: with a single function, it is difficult to meet complex process requirements, such as gradient material preparation, multi-layer material sintering, etc.
Multi temperature zone customized rotary tube furnace: supports vacuum or specific atmosphere environments (such as inert gases, reducing gases), and can be tilted for easy sample collection and placement or special process operations. For example, in the preparation of perovskite solar cells, a rotary tube furnace dynamically rotates the substrate to evenly spread the perovskite precursor solution, combined with multi temperature gradient annealing to reduce film defects and improve the device’s photoelectric conversion efficiency to over 22%.

4. Intelligent operation: reduce human error and improve efficiency
Ordinary tube furnace: operation relies on manual experience, and the heating, insulation, and cooling curves need to be manually controlled, which can easily introduce errors.
Multi temperature zone customized rotary tube furnace: equipped with intelligent control system (such as PLC or DCS), supporting multi-stage program temperature control, real-time data monitoring and fault diagnosis. Users can preset process parameters through the touch screen or upper computer software, and the equipment will automatically run, reducing human intervention and ensuring the reproducibility of experimental results. For example, in metal material heat treatment, intelligent temperature control systems can maintain temperature stability for a long time, avoiding material performance degradation caused by temperature fluctuations.

5. Material Applicability: Covering Core Needs in the New Energy Sector
Ordinary tube furnace: limited applicability, difficult to meet the stringent requirements of new energy materials for temperature, atmosphere, and uniformity.
Multi temperature zone customized rotary tube furnace: widely used in fields such as lithium-ion batteries, fuel cells, solar cells, and energy storage materials. For example:
Lithium ion batteries: Optimizing the crystallinity of positive and negative electrode materials through multi temperature zone temperature control to improve battery cycle life.
Fuel cell: Preparation of highly active catalysts in a rotating environment to improve catalytic efficiency.
Solar cells: using gradient annealing to reduce defects in perovskite films and improve photoelectric conversion efficiency.
Energy storage materials: High specific surface area carbon based materials are synthesized through rapid thermal shock to enhance the energy density of supercapacitors.

6. Energy conservation and environmental friendliness: optimizing energy utilization and reducing operating costs
Ordinary tube furnace: severe heat loss, low energy utilization efficiency, and lack of data recording function, making it difficult to optimize process parameters.
Multi temperature zone customized rotary tube furnace: using high-quality insulation materials and efficient heating elements to reduce heat loss; The intelligent temperature control system dynamically adjusts power according to actual needs to reduce energy consumption. For example, a certain enterprise customized equipment by optimizing the temperature zone layout and rotation speed, which increased energy utilization efficiency by 30% and single batch production by 40%.
