1. Temperature requirements
Temperature range: Silicon carbon rod box type atmosphere furnace is usually used for high-temperature heat treatment, with a temperature range generally between 1000 ℃ and 1500 ℃. Select the appropriate temperature range based on specific experimental or process requirements. For example, processes such as high-temperature tempering and annealing of metal materials may require a temperature of around 1200 ℃.
Temperature control accuracy: Temperature control accuracy has a significant impact on experimental results. Choosing equipment with high temperature control accuracy, such as equipment with a temperature control accuracy of ± 1 ℃, can ensure the accuracy and reproducibility of experimental results.

2. Furnace volume and size
Furnace volume: Determine the furnace volume based on the size and quantity of experimental samples. The furnace volume should be at least 1.5 times the total volume of the sample to ensure sufficient space for the material inside the furnace and sufficient heat transfer to each part.
Furnace dimensions: including length, width, and height. For long strip materials, it is necessary to choose electric furnaces with longer furnace lengths; For materials that require layered placement, ensure that the furnace height is sufficient. At the same time, the size of the furnace should also consider the placement of materials to ensure that they can be placed smoothly and heated evenly.

3. Heating element and temperature control system
Heating element: Silicon carbon rod is a commonly used heating element with good high temperature resistance and heating speed. Choose high-quality silicon carbide rods to ensure the stability and durability of the equipment. Temperature control system: A good temperature control system can achieve precise temperature control and multiple heating and cooling programs. For example, devices using intelligent PID temperature control instruments have temperature compensation and calibration functions, which can achieve precise temperature control.

4. Atmosphere control system
Atmosphere type: Select equipment that can accurately control the gas composition inside the furnace according to the requirements of the experiment or process. For example, for certain materials, heat treatment is required in an inert gas atmosphere such as nitrogen, argon, or hydrogen.
Atmosphere pressure: Some equipment has the function of regulating the atmosphere pressure inside the furnace to meet the processing requirements of different materials.

5. Sealing performance
Sealing performance of furnace body: Good sealing performance of furnace body helps to maintain the stability of atmosphere and prevent external air from entering the furnace and affecting the experimental or process results.

6. Safety performance
Safety device: Select equipment with safety measures such as over temperature protection and leakage protection to ensure safe use.
Convenient operation: The operation interface is simple and easy to understand, making it convenient for laboratory personnel to use.

7. After sales service
After sales service policy: Pay attention to the manufacturer's after-sales service policy to ensure timely technical support during equipment use.

8. Other factors
Equipment power and voltage: Select appropriate equipment power and voltage according to experimental or production needs.
The heating rate of the equipment: The heating rate affects the efficiency of the experiment or process. Choosing equipment with a faster heating rate can improve work efficiency.
Material and structure of equipment: The furnace material should have good high temperature resistance and insulation performance to reduce heat loss. The furnace structure should be compact, stable, and easy to operate and maintain.
