Detailed Product Description
2800℃ Graphitization Furnace with Ar/N2 Atmosphere for Carbon
Fiber
Description:
IGBT Power Advantage: The 2800℃ vacuum induction graphitization
furnace uses IGBT power control, which has the characteristics of
high power factor, low energy loss and strong anti-interference
ability, ensuring the stability and reliability of the equipment
during long-term operation.
Vacuum & Atmosphere Control: The furnace body has excellent
sealing performance, which can realize vacuum pumping and filling
of argon/nitrogen protective atmosphere (micro positive pressure).
It effectively prevents material oxidation and carbon loss during
the graphitization process.
Processable Materials: Covering a variety of high-demand materials,
such as carbon fiber, carbon materials, carbon nano materials,
negative electrode materials, graphite powder, rare earth
materials, rhenium materials, pet coke, green coke, radiation-proof
materials and contacting terminal materials.
Operational Features: Equipped with an intelligent man-machine
interaction interface, which can easily set and monitor the process
parameters. The built-in over-temperature alarm, vacuum leakage
detection and other safety mechanisms ensure the safety of
operators and equipment. It is suitable for various production and
R&D scenarios.
Application:
This 2800℃ Vacuum Induction Graphitization Furnace is widely
applicable in multiple high-temperature material processing
scenarios:
Carbon fiber processing: Carbonization and graphitization treatment
of carbon fiber precursors to enhance their thermal stability and
mechanical strength.
Battery material production: High-temperature treatment of battery
negative materials (e.g., graphite negative electrodes) to optimize
their electrochemical performance.
Advanced material manufacturing: Graphitization of graphite powder
and graphene.
Protective atmosphere processing: Finishing graphitization of
products under Argon protective atmosphere to meet the requirements
of carbon material internal molecular structure modification and
performance.
