The rotary experimental electric furnace is a tube type heat treatment furnace with a rotating mechanism installed on the furnace tube, which can be driven by a motor to achieve uniform rotation. The rotary experimental electric furnace has the advantages of uniform heat treatment, higher efficiency, continuous feeding and unloading, and unmanned operation, and is highly favored by many university laboratories and industrial and mining enterprise laboratories. So what aspects should we pay attention to when choosing a rotary experimental electric furnace? Let's take a look below!

1. Clarify experimental requirements and determine key parameters
Temperature range: Select an appropriate upper temperature limit based on the characteristics of the experimental material. For example, high-temperature ceramic sintering requires an electric furnace above 1600 ℃, while metal heat treatment may only require around 1000 ℃. It is necessary to confirm whether the rated temperature of the electric furnace meets the experimental requirements and leaves a margin.
Heating rate and temperature control accuracy: Rapid heating can shorten the experimental cycle, but it requires balancing the equipment life; The temperature control accuracy directly affects the experimental results. For example, an accuracy of ± 1 ℃ is suitable for precision material synthesis, while ± 5 ℃ may meet general heat treatment requirements.
Rotation speed and stability: The rotation speed needs to be adjustable to adapt to different experiments, such as powder sintering requiring low-speed uniform heating, while film deposition may require high-speed rotation. Attention should be paid to the stability of the rotating mechanism to avoid sample detachment or uneven temperature caused by vibration.

2. Pay attention to the structure and material of the furnace body
Furnace material: High temperature experiments require the use of corrosion-resistant and anti-oxidation materials, such as alumina (corundum), silicon carbide, or quartz; Low temperature experiments can choose stainless steel furnaces. The material directly affects the furnace life and experimental purity.
Heating element: Silicon molybdenum rod is suitable for high temperatures above 1200 ℃, silicon carbon rod is suitable for medium high temperatures (1000-1400 ℃), and resistance wire is suitable for low-temperature experiments. Choose the appropriate heating element based on the temperature range and pay attention to its lifespan and energy consumption.
Rotating mechanism design: It is necessary to confirm the sealing and high temperature resistance of the rotating shaft to avoid lubricant evaporation or leakage at high temperatures. At the same time, it is necessary to check the load-bearing capacity of the rotating mechanism to ensure that it can stably support the weight of the sample.

3. Evaluate functional configuration and scalability
Atmosphere control: If the experiment needs to be conducted in an inert or reducing atmosphere, an electric furnace with gas inlet and vacuum pumping functions should be selected, and its sealing and gas flow control accuracy should be confirmed.
Program temperature control function: The electric furnace that supports multi-stage heating, insulation, and cooling curves can simplify complex experimental processes and improve repeatability. Need to confirm the response speed and stability of the temperature control system.
Data recording and transmission: An electric furnace with real-time recording and transmission functions for temperature, time and other parameters, which facilitates experimental data management and analysis, especially suitable for long-term continuous experiments.

4. Emphasize safety performance and operational convenience
Safety protection measures: It is necessary to confirm whether the electric furnace has functions such as over temperature alarm, leakage protection, emergency stop, etc., and check whether the furnace door interlocking device is reliable to avoid danger caused by misoperation.
Operation interface and maintenance: Touchscreen or intelligent control system can simplify the operation process and reduce human error; Modular design facilitates equipment maintenance and component replacement, reducing downtime.

5. Consider brand reputation and after-sales service
Brand reputation: Choosing a brand with a good reputation in the field of laboratory equipment can reduce equipment failure rates and usage risks. Brand reputation can be understood through channels such as user reviews and industry reports.
After sales service: It is necessary to confirm whether the supplier provides installation, debugging, operation training, regular maintenance, and quick response repair services to ensure the long-term stable operation of the equipment.
