Ultra high temperature vertical continuous graphitization furnace

Product Introduction of 3200 ℃ Ultra High Temperature Continuous Graphitization Furnace

With the global demand for high-purity graphite materials required for secondary batteries, electric vehicles, and solar power generation skyrocketing, domestic enterprises are continuously developing various types of ultra-high temperature furnaces, which can make excellent responses within the ultra-high temperature range of 2500 ℃ or higher according to the material type. With the increasingly fierce competition for improving the performance of graphite materials, the graphitization process has also become higher than the conventional 2700-2800 ℃. Our company's latest research and development of ultra-high temperature continuous graphitization furnace for negative electrode materials can operate stably and continuously at 3200 ℃ for mass production. Compared with the traditional single furnace heating production mode, the continuous furnace has a series of advantages such as energy conservation, efficiency, product stability, and good consistency, achieving a perfect replacement for the single furnace production mode currently used by most manufacturers.

This type of continuous high-temperature equipment can not only be used for graphitization of negative electrode materials, but also for graphitization of carbon and carbon products, graphitization of graphene thermal conductive films, high-temperature purification of graphite and graphite products, and high-temperature heat treatment of graphite paper. The business scope covers key areas of national concern such as new energy vehicles, mobile communication, photovoltaics, military industry, aerospace, and nuclear energy.

Continuous graphitization is a method of converting carbon raw materials into graphite structures through high-temperature treatment, which has many excellent performance characteristics and is suitable for applications in various fields. Firstly, continuous graphitization can improve the conductivity of carbon materials, reduce their electrical resistivity, and make them more widely used in the electronic field. Secondly, continuous graphitization can increase the strength and hardness of materials, improve their mechanical properties, and make them suitable for preparing high-strength and high hardness materials, such as carbon fiber composites. In addition, continuous graphitization can also improve the heat resistance and chemical stability of materials, enabling them to perform better in high temperature and corrosive environments. In the field of electronics, continuously graphitized carbon materials are widely used in the preparation of conductive films, electrode materials, electromagnetic shielding materials, and so on. Due to its excellent conductivity and mechanical properties, continuously graphitized carbon materials are often used to prepare flexible electronic products, such as flexible displays, sensors, etc. In the field of aerospace, continuously graphitized carbon materials are also used to prepare structural materials for spacecraft, which have the characteristics of lightweight and high strength, and can improve the performance of spacecraft. In addition, continuously graphitized carbon materials are also used to prepare energy storage materials, optical materials, etc., and have broad application prospects.

The characteristics of continuous graphitization of negative electrode materials mainly include the following points:

Improving conductivity: Continuous graphitization can effectively improve the conductivity of negative electrode materials, making electron transfer smoother in the material, reducing resistance, and improving the charging and discharging efficiency of batteries.
Improving cycling stability: Continuous graphitization can improve the structural stability of negative electrode materials, reduce capacity degradation and structural damage during cycling, and extend the cycling life of batteries.
Improving energy density: Through continuous graphitization treatment, the specific surface area and charge discharge capacity of the negative electrode material can be increased, thereby increasing the energy density of the battery and prolonging its service life.
Improving safety performance: Continuous graphitization can improve the thermal stability and high temperature resistance of negative electrode materials, reduce the oxidation and thermal runaway reactions of materials at high temperatures, and improve the safety performance of batteries.
