Temperature range and temperature control accuracy:
According to the experimental requirements, clarify the required temperature range and ensure that the selected electric furnace can cover this range.
The precision of temperature control is crucial for experimental results, therefore an electric furnace with a high-precision temperature control system should be selected. The intelligent temperature control system can achieve the compilation and fully automatic control of multi-stage rise, hold, and drop curves, improving the accuracy and reliability of experiments.

Heating method and efficiency:
Choose a suitable heating method based on experimental requirements, such as resistance wire heating. Choose a suitable heating environment for yourself.
Choose electric furnaces with high heating efficiency and low energy consumption to reduce experimental costs and protect the environment. For example, furnace materials made of ceramic fibers have the characteristics of small heat capacity and fast heating, which can improve heating efficiency.

Furnace shape and size:
Choose the appropriate furnace shape based on the shape and size of the heated workpiece. For example, continuous electric furnaces are suitable for long or tubular workpieces, while trolley furnaces are more suitable for large or heavy workpieces.
Ensure that the furnace size is sufficient to accommodate the workpiece to be heated and leave appropriate space for operation and maintenance.

Material and Durability:
The furnace material should be selected with high temperature resistance, good seismic performance, and resistance to rapid cooling and heating to ensure the long-term stable operation of the equipment.
The shell should be made of good steel plate profiles, with a surface sprayed with colored plastic, and have the characteristics of pleasing to the eye, heat resistance, and corrosion resistance. Avoid choosing a shell made of thin iron sheet to prevent deformation and short service life of the electric furnace.

Security:
Ensure that the electric furnace has good safety performance, such as over temperature protection, leakage protection, etc., to ensure the safety of experimental personnel.
It is strictly prohibited to stack flammable and explosive materials, gas cylinders, etc. around heating equipment to prevent fire or explosion accidents.

Brand and after-sales service:
Choose reputable brands and suppliers to ensure the quality and after-sales service of electric furnaces.
Prioritize manufacturers who can provide relevant accessory equipment and professional technical support.

Price and Budget:
Select a suitable electric furnace based on the experimental budget, ensuring that products with high cost-effectiveness are chosen as much as possible while meeting performance and experimental requirements.
