What are the differences between customized tube furnaces and traditional experimental furnaces?

There are significant differences between customized tube furnaces and traditional experimental furnaces in multiple aspects. The following is a detailed analysis of the main differences between the two:
1. Structure and Design
Customized tube furnace:
The furnace body is usually made of high-quality steel plates with exquisite craftsmanship, with a beautiful and elegant appearance that does not peel off the paint for a long time.
The furnace tube is the core component, and commonly used materials include corundum tube, quartz tube, or stainless steel tube, which have excellent high temperature resistance and chemical stability.
The furnace is usually made of alumina refractory material, which has good insulation performance and durability.
Both ends are equipped with sealed flanges, which can achieve the functions of pre vacuuming and introducing various atmospheres.
Traditional experimental furnaces (such as box furnaces):
The appearance is similar to a box, and the furnace is generally square. The size specifications can be customized.
The door is opened in front, usually pulled outward, and equipped with a door stopper to enhance insulation effect.
High purity alumina polycrystalline fibers are also commonly used as furnace materials, but their structure and design are relatively simple.
2. Heating method and temperature control
Customized tube furnace:
Usually, radiation heating is used to heat the sample by generating heat around the pipeline.
The heating area and constant temperature area are clear, and the temperature area and number of tubes can be customized according to needs.
High temperature control accuracy, usually up to ± 1 ℃, and constant temperature accuracy can also reach ± 2 ℃.
Traditional experimental furnace:
Radiation heating or convection heating can be used.
The temperature uniformity inside the furnace is relatively poor, mainly suitable for materials with low heating temperature requirements.
The precision of temperature control and constant temperature may not be as high as that of customized tube furnaces.
3. Function and adaptability
Customized tube furnace:
Highly customized, various functions and configurations can be customized according to customer needs.
Multiple atmospheres (such as oxygen, nitrogen, hydrogen, argon, etc.) can be introduced to achieve heating treatment under different atmospheres.
The vacuum degree can be adjusted, suitable for experiments and production that require high or low vacuum environments.
The heating material is flexible, and the temperature range and number of pipes can be customized according to demand.
Traditional experimental furnace:
The function is relatively single and usually only applicable to specific types of experiments and production.
The atmosphere control and vacuum degree adjustment functions are limited.
The heating material and temperature range are relatively fixed.
4. Application scenarios
Customized tube furnace:
Widely used in laboratories or small-scale production to perform high-temperature treatment or special heat treatment processes on a small number of samples.
Suitable for experimental and production scenarios that require precise control of temperature, atmosphere, and vacuum degree.
Traditional experimental furnace:
Usually used for heating larger, thicker flat or block shaped samples.
Suitable for experimental and production scenarios where temperature requirements are not particularly strict, and atmosphere and vacuum control requirements are not high.
In summary, customized tube furnaces have shown significant advantages in terms of structure and design, heating methods and temperature control, functionality and adaptability, and application scenarios. These advantages enable customized tube furnaces to meet the specific needs of different industries and experiments, improving the efficiency and quality of experiments and production.
