Structural composition
Furnace body: It usually adopts a double-layer shell structure, and insulation materials such as alumina polycrystalline fibers can be filled in the middle to reduce heat loss and improve insulation performance. The material of the furnace body is generally carbon steel or stainless steel, which has good strength and corrosion resistance.
Heating elements: Common ones include resistance wires, silicon carbide rods, silicon molybdenum rods, etc. These heating elements are distributed in different temperature zones and generate heat by passing current, providing the required heating environment for the materials inside the furnace.
Furnace tube: High purity quartz tube, stainless steel tube, high-purity alumina tube, or recrystallized silicon carbide tube are commonly used, which have excellent high temperature resistance and corrosion resistance, ensuring long-term stability and reliability of the experimental process.
Temperature control system: Each temperature zone is equipped with an independent temperature controller and thermocouple. The temperature controller generally adopts artificial intelligence PID instrument, which can automatically control the temperature, has bidirectional anti parallel thyristor voltage regulation function, can accurately control the temperature of the electric furnace, and has current limiting function.
Transmission device: Some tubular multi temperature zone electric heating furnaces are also equipped with transmission devices, such as rotating or tilting mechanisms, which can evenly heat and mix the materials inside the furnace tubes, which is conducive to improving experimental results.

Working principle
By setting the temperature range and heating time required for each temperature zone through the control system, the heating element starts working and applies heat to the furnace tube. Heat is transferred in the furnace through radiation, convection, and conduction, gradually raising the temperature of the materials inside the furnace tubes.

Characteristic
Accurate temperature control: Each temperature zone can be independently temperature controlled with high precision, generally up to ± 1 ℃, which can meet the processing needs of different materials under different temperature conditions.
Temperature gradient setting: It can form multiple different temperature zones within the same furnace tube, which can be used to study the physical and chemical property changes of materials under different temperature gradients, providing experimental basis for material design and performance optimization.
Atmosphere control: It can be used in conjunction with vacuum systems or gas input devices to create a vacuum environment inside the furnace or introduce specific protective gases such as nitrogen, argon, hydrogen, etc., to meet the material research and preparation requirements with strict oxygen content requirements.
Easy to operate: Usually using a touch screen or computer control system, the operation interface is simple and intuitive, making it convenient for experimental personnel to set parameters, start, stop, and other operations. It can also monitor the temperature inside the furnace, the working status of each temperature zone, and other information in real time.

Application area
Research field: Provides powerful tools for materials science research, which can be used to study the physical and chemical property changes of materials at different temperatures, explore the phase transition laws, thermal stability, etc. of materials, and can also be used to simulate the temperature changes of materials in actual working environments.
Industrial production: can be used for heat treatment of metal materials, such as annealing, tempering and other processes, to improve the mechanical and process properties of materials. At the same time, it can also be used for sintering and melting processes of inorganic non-metallic materials such as ceramics and glass, achieving efficient preparation of materials.
In the field of new energy, it can be used for the preparation and performance testing of battery materials, such as high-temperature preparation and performance optimization of lithium-ion battery electrode materials, solar cell materials, etc., to promote the development of new energy technology.
In the field of material processing, it can be used for the synthesis of nanomaterials, achieving uniform growth and morphology control of nanoparticles through precise temperature gradient control. In addition, it can also be used for the preparation of thin film materials by depositing or annealing at different temperature ranges to obtain thin film materials with specific structures and properties.
