Structure and principle of continuous graphitization furnace
Thread Content
Development of large-scale continuous graphitization furnace---Industrial Heating. 2003, Vol40, No.4, 33-39 (Japan) In recent years, in view of the need for heat treatment of carbon powder materials for Ceng battery negative electrodes and various solid carbon materials, Japan ICC Company has successfully developed a continuous graphitization furnace with a temperature control range of 1 500 3 000 ℃ and atmosphere adjustment. The design, manufacturing and actual operating results of the above-mentioned graphitization furnace are focused on. The structural diagram and technical parameters of the continuous graphitization furnace are given. It is pointed out that the furnace not only has a wide operating temperature range and adjustable atmosphere, but also has a short processing cycle and significant energy saving effect. Good working environment and other advantages. I would like to ask if anyone has this paper, or can you tell me which foreign companies have mature continuous graphitization furnaces.

The main carbonization furnace includes a vertical channel and a horizontal channel formed by an upper furnace body, an intermediate water-cooling connecting sleeve and a lower furnace body. The upper and lower furnace bodies are connected through an intermediate water-cooling connecting sleeve. The upper furnace body mainly supports It is responsible for heating and other tasks. The middle water-cooling connecting sleeve is the cooling area part of the vertical channel. The lower furnace body is mainly responsible for cooling, discharging and other tasks. The boats containing materials are overlapped and stepped into the vertical channel of the furnace body in sequence. The manipulator pushes the carbonized material boats into the horizontal channel and pushes them out of the furnace body. The furnace adopts vertical heating, continuous carbonization, and horizontal cooling to discharge materials. The high-temperature furnace does not need to support the weight of boats and materials. It also has fast cooling speed, high output, and good product quality. It can better solve the above problems existing in horizontal continuous furnaces and vertical batch furnaces.

Guiyang Aluminum Magnesium Design and Research Institute Co., Ltd. has a feeding funnel on the top of the furnace and a storage bin above the feeding funnel. The storage bin has a three-section structure, that is, one middle bin and two side bins.； The feeding funnel has a double-layer circular structure, which is a combination structure of the inner funnel and the outer funnel. An annular exhaust channel is formed at the bottom between the inner and outer funnels. The annular exhaust channel is connected to the exhaust pipe. ； The upper electrode is set in the middle of the furnace top and the feeding funnel, the lower electrode is set in the middle of the lower section of the furnace body, coarse-grained materials are placed in the middle of the furnace body, and fine-grained materials are placed between the refractory lining of the furnace body and the coarse-grained materials. ； A discharge mechanism is provided at the bottom of the furnace body. A special feeding funnel is set up on the top of the furnace to allow carbon raw materials to be added to the graphitization furnace according to different particle sizes. Coarse-grained materials are placed in the center of the furnace, and fine-grained materials are placed outside it. During the heat treatment process, electric current passes through the coarse-grained materials, and the resistance characteristics of the coarse-grained carbon raw materials are used to heat them to the temperature required for heat treatment, thereby achieving graphitization. ； Fine-grained materials are mainly used for heat insulation to maintain the furnace wall temperature below 1500°C. The heat-treated carbon materials are cooled and then screened. The coarse-grained materials are used as graphitized products, while the fine-grained materials can be used as electrical burning materials or can be re-entered into the furnace for use as heat insulation materials.

Each crucible of IHI Mechanical Systems Co., Ltd. passes through the heating zone, energization zone, and cooling zone in the furnace at one time. In the conductive area, the conductive collecting rods move up and down at intervals and are inserted into the preheated crucible for further heating.
