20 graphitization furnaces, annual output of 50,000 tons, constructed in 2018

　　A graphitization furnace is a high-temperature processing equipment used for the sintering and graphitization of carbon materials. It has the following main characteristics and applications: 
　　Characteristics 
　　High-temperature processing capability: The operating temperature of a graphitization furnace can reach up to 3000℃. It features high efficiency and energy saving, and is equipped with an online temperature measurement and control system for real-time monitoring and automatic adjustment of the furnace temperature. 
　　Structural characteristics: Graphitization furnaces typically consist of a refractory material-lined furnace bottom and two end walls fitted with conductive electrode groups, arranged in a rectangular shape. The end walls fix the conductive electrode groups. The outer side is lined with refractory bricks or carbon blocks, and the inner side is lined with graphite blocks. The middle of the wall is filled with graphite powder to form a sealed filler space. 
　　Classification: According to the heating method, they can be divided into direct heating furnaces and indirect heating furnaces; according to the operating mode, they can be divided into batch type and continuous type. Direct heating furnaces have a simple structure but high energy consumption, while indirect heating furnaces have high thermal efficiency but complex structures; batch type processes are simple but energy-intensive, while continuous type processes have short production cycles and are environmentally friendly. 
　　Applications 
　　Carbon material conversion: The graphitization furnace uses high-temperature processing to cause carbon materials to undergo a graphitization reaction, obtaining graphite materials with excellent electrical conductivity, thermal conductivity, and chemical stability. It is widely used in battery anode materials, graphite powder purification, etc. 
　　Specific industry applications: Suitable for high-temperature graphitization processing of carbon material structural components, C/C composite materials, carbon fibers, carbon materials, flake graphite, and other graphite materials. In addition, it is also used for high-temperature physical purification of graphite powder, spherical graphite, and carbon nanotubes for battery anode materials.
