Hunan Jingtan Automation Equipment Co., LTD.

  The high-temperature graphitization furnace is a core equipment developed by Hunan Jingtan Automation Equipment Co., Ltd. for the high-temperature treatment of high-end carbon materials such as lithium battery anode materials, carbon fibers, and graphene. In the production of lithium battery anode materials, the degree of graphitization directly determines the capacity and cycle life of the battery, and the improvement of the degree of graphitization must rely on a sufficiently high heat treatment temperature and a pure atmosphere environment. The high-temperature graphitization furnace for refined carbon adopts advanced heating technology, with a temperature that can reach approximately 2600℃, fully meeting the sintering and graphitization requirements of various materials. Under ultra-high temperature vacuum or inert gas protection conditions, carbon atoms gain sufficient energy to rearrange from disordered layers into ordered graphite crystals. At the same time, impurities in the raw materials are fully volatilized and discharged, achieving the dual goals of purification and graphitization. The intelligent temperature control system of the high-temperature graphitization furnace is the core guarantee for achieving high-quality processing. The equipment adopts a digital intelligent temperature control system, which automatically and precisely completes the temperature measurement and control process. The system can heat up according to the given temperature rise curve and can store 20 different process heating curves totaling 400 segments. The operator only needs to invoke the process formula of the corresponding product, and the equipment can automatically execute the entire process of heating, holding and cooling without the need for manual supervision, significantly reducing the impact of human operational errors on product quality. The temperature uniformity in the furnace working area has been optimized through design to ensure that products at different positions within the same furnace pass achieve consistent graphitization effects.   The application scope of high-temperature graphitization furnaces covers a wide range of fields from carbon materials to ceramic materials. The equipment can be used for the sintering of battery anode materials, carbon material structural components, C/C composite material products, carbon fibers, carbon materials, carbon fiber ropes, and the high-temperature graphitization of phosphorus flake graphite and other graphite materials. For the production of thermal conductive graphite film, the equipment can be combined with carbonization furnaces at 1200-1600℃ to form a complete thermal conductive graphite film production line. The equipment required for the preceding and subsequent processes of the equipment is reasonably matched, and various sizes and specifications of thermal conductive graphite films can be produced. The vacuum and atmosphere system of the high-temperature graphitization furnace is the hardware guarantee for its purification capacity. The equipment can operate under vacuum or inert gas protection, effectively removing the residual active gas in the furnace and preventing carbon materials from oxidizing at high temperatures. The comprehensive PLC water, electricity and gas automatic control and protection system monitors the equipment's operating status in real time. When an abnormality occurs, it automatically alarms and executes protection programs, ensuring the safe and reliable operation of the equipment under ultra-high temperature conditions. The equipment adopts an internal circulation pure water cooling system and is equipped with a digital flow monitoring system. With its comprehensive technical advantages of "ultra-high temperature of 2600℃, intelligent temperature control and wide application", the high-temperature graphitization furnace of Jingcarbon has become an important piece of equipment in the new energy materials and special carbon materials industries.

Graphite materials are widely used, but ordinary graphite has many impurities and a loose structure, with obvious performance ceilings. Genuine high-purity graphite is the "hot commodity" in high-end fields such as aerospace and electronics. Where does high-purity graphite come from? The answer lies in the cracking process - through high-temperature cracking, the carbon source gas is decomposed and deposited to obtain graphite products with a denser structure and higher purity. The graphite cracking furnace is precisely the carrier of this process.   The product range of Hunan Jingtan Automation Equipment Co., Ltd. covers high-temperature graphitization furnaces, vacuum carbonization furnaces and other graphite-related equipment, with graphite cracking furnaces being in line with it. Relying on the company's R&D strength in the field of thermal equipment, the insulation structure of the furnace body, heating method and atmosphere control have been systematically designed, providing reliable equipment for the stable production of high-purity graphite.   Its advantage lies in purity and consistency. Under high-temperature conditions, the cracking is thorough, impurities are effectively removed, and the quality of graphite is stable and reliable. Precise control of atmosphere and temperature ensures minimal differences between batches and predictable performance of finished products, laying a solid foundation for downstream high-end applications and giving enterprises more confidence in quality management.   Graphite cracking furnaces are widely used in aerospace, electronics, metallurgy, carbon-carbon composite materials and other fields, and are the core equipment for producing high-purity graphite products. For carbon material enterprises, having a reliable cracking furnace is equivalent to holding the ticket to the high-end market - it is indispensable precisely because high-end applications cannot do without it.

Many engineers specializing in carbon materials and special ceramics have the same question: How can the surface of the workpiece be both hard and wear-resistant, withstanding the tests of high temperatures and wear? One of the answers is the silicon diffusion process - in a high-temperature environment, silicon elements are evenly diffused into the surface of the material to form a hard silicide layer, transforming ordinary materials. The key equipment for completing this step is precisely the high-temperature silicon diffusion sintering furnace.   Hunan Jingtan Automation Equipment Co., Ltd. is a manufacturing enterprise integrating the research and development, production and sales of thermal engineering equipment. The high-temperature silicon diffusion sintering furnace is one of its representative products. Relying on the company's years of accumulated technical experience in vacuum furnaces and sintering furnaces, the equipment has been strictly controlled from the furnace body structure design to the temperature control system to ensure that the silicon infiltration process is stable, controllable and repeatable.   The advantage of this stove lies in its uniformity and high efficiency. The temperature field distribution inside the furnace is uniform, and all parts of the material are heated consistently. The thickness of the silicon diffusion layer is uniform, and the difference between batches is small. At the same time, it combines the two major functions of silicon infiltration and sintering. With just one loading into the furnace, multiple processes can be completed, eliminating the need for repeated temperature changes and waiting. The production pace is faster and the consistency of the finished products is more guaranteed.   High-temperature silicon diffusion sintering furnaces are widely used in fields such as hard alloys, refractory metals, special ceramics, and carbon-carbon composite materials, providing high-performance components that are wear-resistant and heat-resistant for industries like aerospace, electronics, transportation, and machinery. For enterprises that pursue product performance upgrades and aim to enter the high-end market, it is an important piece of equipment for enhancing the competitiveness of materials and deserves serious attention.

With the rapid development of the new materials industry, the market's requirements for the purity and mechanical properties of sintered workpieces have been continuously increasing. Traditional sintering equipment is difficult to avoid problems such as high-temperature oxidation and impurity intrusion. Vacuum sintering furnaces, with their closed vacuum heat treatment working mode, have become important production equipment for many new materials enterprises and are widely used in experimental research and development in scientific research institutes as well as industrial batch production scenarios. Hunan Jingtan Automation Equipment Co., LTD., based on its accumulation of thermal equipment technology, iterates equipment design in response to various pain points in actual production. While ensuring the effect of heat treatment, it optimizes the operation logic of the equipment, lowers the usage threshold for on-site personnel, and ADAPTS to the sintering operations of multiple types of materials.   During the actual production process, customers often encounter various difficult problems. Some enterprises have reported that the operating parameters of the equipment are all normal, but the performance of the finished products fluctuates significantly. This kind of phenomenon is often not due to hardware failure, but rather because the loading method and the timing of atmosphere switching do not match the characteristics of the material. If the workpieces are placed too densely, it will hinder the circulation of heat flow inside the furnace, resulting in inconsistent heating of workpieces at different positions. There are still users who confuse the applicable scenarios of vacuum and atmosphere protection processes. For some materials, protective gas needs to be introduced at specific stages. A single vacuum mode throughout the process can lead to processing defects. Many users tend to overlook the key points of switching between process stages.   How can vacuum sintering furnaces in the processing and production of new materials balance product quality and the convenience of on-site operation and maintenance   Compared with ordinary sintering equipment, vacuum sintering furnaces have very prominent comprehensive advantages. The absence of an oxidizing atmosphere inside the furnace can ensure the purity of materials, reduce surface defects of workpieces, and improve the overall qualification rate of finished products. The temperature control system of the equipment responds smoothly and can fully reproduce the preset entire heat treatment process, ensuring that the performance of products from different batches tends to be uniform and reducing the loss caused by batch differences. The overall structure of the equipment fully takes into account the requirements for later maintenance. Key components are easy to disassemble and maintain, and routine maintenance can be completed without complex disassembly. This not only meets the strict production standards of high-end materials but also takes into account the practical needs of on-site operation and maintenance in the factory.   To ensure the long-term stable output of the equipment, both standardized operation and regular maintenance are indispensable. After each sintering operation, the volatile residues inside the furnace should be cleaned up in a timely manner to prevent the accumulation of residues from corroding the insulation and heating components. Operators need to be familiar with the process boundaries of different materials, and should not set temperature and vacuum parameters beyond the range at will to reduce abnormal equipment wear and tear. When abnormal working conditions occur, the manufacturer's technical team can provide remote and on-site technical support to assist in troubleshooting problems. At the same time, they can also assist in debugging process plans based on the new product development needs of customers. Hunan Jingtan Automation Equipment Co., Ltd. combines equipment manufacturing with process services, helping enterprises make good use of vacuum sintering furnaces and facilitating the stable implementation and production of new material projects.
