1. Material type and process requirements
Material type: Determine the type of material that needs to be processed, such as powder materials, ceramics, metallurgical materials, etc. Different materials may require different furnace materials and heating methods.
Process requirements: Understand the temperature range, heating speed, insulation time, and other process requirements required for the experiment in order to select a rotary furnace that meets the requirements.

2. Furnace type and structure
Furnace type selection: There are various types of experimental rotary furnaces, such as horizontal, vertical, single tube, multi temperature zone, etc. Select the appropriate furnace type based on the specific requirements of the experiment. For experiments that require high surface utilization, a furnace type with single row tubes and double-sided radiation can be chosen; For experiments with high design loads, it may be necessary to select cylindrical furnaces, multi temperature zones, etc. through technical and economic comparisons.
Furnace tube material: The furnace tube material directly affects the high temperature resistance and service life of the furnace. Common furnace tube materials include stainless steel, nickel based high-temperature alloys, corundum tubes, quartz, silicon carbide, etc. Select the appropriate furnace tube material based on the experimental temperature and requirements.

3. Performance parameters
Heating method: The main heating method is electric heating, which has the advantages of high temperature control accuracy and easy operation. It is a commonly used heating method for experimental rotary furnaces.
Temperature control accuracy: High precision temperature control can ensure the accuracy and repeatability of experimental results, and is one of the important performance indicators of experimental rotary furnaces.
Furnace tube speed and inclination angle: The furnace tube speed and inclination angle can be adjusted according to experimental requirements to optimize experimental results. For example, adjusting the furnace tube speed can improve the heating uniformity of materials.
Atmosphere control: Some experiments require specific atmospheric conditions, such as nitrogen, argon, and other inert gas protection. Therefore, when choosing a rotary furnace, its atmosphere control capability needs to be considered.

4. Security performance
The experimental rotary furnace may involve dangerous factors such as high temperature and high voltage during operation, so safety performance is very important. Choose a furnace with comprehensive safety protection measures, such as installing leakage protection switches and ensuring good sealing of the furnace door, to ensure the safety and reliability of the experimental process.

5. After sales service
Choose manufacturers or brands with good after-sales service so that they can receive timely technical support and solutions when encountering problems during use.

6. Budget and cost-effectiveness
The price of experimental rotary furnaces varies depending on factors such as brand, model, and performance. When choosing, you can weigh your budget and actual needs and choose products with high cost-effectiveness.
