Large graphite furnace

Uses: used in ultra-high temperature furnace within 3000 ℃, for a variety of high thermal conductivity graphite film (PI film), lithium battery anode material, carbonized carbonized carbon material production of carbon and graphite materials, graphite technology; carbon fiber filament stereotypes and other graphitized carbon environment may be in sintered material. Maximum operating temperature: 3000 ℃, 2850 ℃ temperature commonly working atmosphere: vacuum replacement Ar2, N2 protection (positive pressure) temperature measurement: infrared optical temperature measuring range 1000 ~ 3000 ℃ or 0 ~ 3000 ℃; Temperature measurement accuracy : 0.2 to 0.75%. Temperature control: process control and manual control; Temperature accuracy: ± 1 ℃ induction heating equipment using frequency power supply, high efficiency: The unique furnace design, greatly improving the temperature uniformity. Limit heating rate: 200 ℃ / min (space heaters, depending on the volume and the furnace hot zone structure may be) the degree of temperature uniformity ± 15 ℃, temperature control accuracy of ± 1 ℃. Low energy consumption: double alumina insulation materials, good heat insulation refractory effect, heat loss, heating speed. Long service life of wearing parts: the crucible bottom cushion has a high strength composite mat hard to ensure that the graphite crucible at a high temperature level even by force, is 1.3 times the life of similar products. A high degree of security: exclusive design furnace explosion-proof valve, safe and reliable. High degree of automation equipment: a fully automated control, touch screen and intuitive display various parameter data, sound the alarm and lock down protection device. Water, electric automatic control, easy operation and simple. 2, the power supply cabinet with fully sealed structure, the cabinet comes with a water-cooled and air-cooled radiator, heat exchange with the outside air is not occurred, advanced temperature control system, imported intelligent digital temperature controller can be used with PLC data communication, Automatic temperature control accuracy to complete the process, the system according to a given temperature curve temperature, and can store a total of 400 segments twenty different process heating curve. 3, in the closed loop water cooling system; digital traffic monitoring system, each channel water from the flow meter monitoring and protection. 4, Chinese Academy of Sciences R & D, production of high-performance gas purifier, gas oxygen content can be reduced to 1PPMV, dew point temperature can be reduced to -70 ℃. 5, furnace conversion using our dedicated high-performance IF converter, to avoid contact with the ignition, such as the traditional bad phenomenon. 6. The heating time and process requirements, a single power supply cabinet configure multiple furnace, respectively, to achieve a single furnace heating and cooling separately, significantly increasing productivity.
