Carbon fiber graphitization furnace

●Application:

For a variety of high conductivity graphite film (PI film), lithium battery anode materials, carbonization and graphitization of carbon materials and production of carbon materials, carbon fiber filament shaped graphitization and other material sintering in the carbon environment.

●Feature:

1.The highest working temperature: 3000℃,common temperature: 2900℃.
2. working atmosphere: vacuum replacing Ar2,N2 protection(micro positive pressure)
3.Temperature measurement: temperature measurement of far infrared optical range 1000~3000℃or 0~3000℃; the accuracy of temperature measurement: 0.2~0.75%.
4.Temperature control: process control and manual control, the accuracy of temperature control: ±1℃
5.Adopting IF power supply induction heating, high efficiency, the unique design of furnace hearth to greatly improve the uniformity of furnace temperature.

6.Double layer material of aluminum oxide for keeping temperature, high efficiency of insulation and fire-resistance, less heating loss, temperature rise faster.

7.The furnace has high strength hard composite felt at the bottom of the crucible, in order to ensure that the graphite crucible stresses uniformly at high temperature level, it is 1.3 times the service life of similar products.

8.Unique design of furnace body explosion-proof valve with safety and reliability.

●Furnace temperature uniformity:

Ultimate the speed-up of temperature: 100℃/min(empty furnace, depends on the volume of the high temperature area and the furnace hearth structure), furnace temperature uniformity ±10℃, the accuracy of temperature control ±1℃.
●High greed automation:
1.Full automatic control, touch screen intuitive display of various parameters data, sound alarm and shut down protection device, full automatical control of water-electric-gas and operating simple.
2.Adopting full seal structure for power supply cabinet, the cabinet equipped with water-cooling and winder-cooling radiator, non-exchange heating with outer air, advantage temperature control system adopting imported digital display intelligent temperature control meter and PLC to achieve the data communication, full automatic high precision complete temperature control process, the system can rise temperature according to the given and can store 20 different heating process curve total of 400 segments.

3.Adopting the seal circulating water cooling system, digital flow monitoring system, each water is monitored and protected by a flow gauge.
4. high performance gas purification machine of CAS R & D, production, the gas oxygen content can be reduced to 1PPMV, dew point temperature can be reduced to -70℃.
5.The furnace body conversion adopts our special high performance frequency converter

to avoid the traditional contactor sparking the bad contact phenomenon

6.According to the heating time and the craft requirement, the single power supply cabinet can be configured with a plurality of furnace bodies, it can achieve to a single furnace body for

Separately finish of heating and cooling, and the production efficiency is greatly improved.
