 Usage: Ultra-high temperature furnace is usually used in the production of various high thermal conductivity graphite film (PI film), lithium battery anode material, carbon material carbonization and graphitization to produce carbon material carbonization, graphitization, carbon fiber filament stereotyping graphitization and other materials sintered in carbon environment.

Maximum service temperature: 3000 C, commonly used temperature 2900 C.
Working atmosphere: vacuum replacement Ar2, N2 protection (micro-positive pressure)
Temperature measurement: Far infrared optical temperature measurement ranges from 1000 3000 or 0 3000 and temperature measurement accuracy: 0.2 0.75%.
Temperature Control: Program Control and Manual Control; Temperature Control Accuracy: +1 Temperature
The equipment adopts medium frequency power supply induction heating with high efficiency: unique furnace design greatly improves furnace temperature uniformity. Limit heating rate: 200 C/min (empty furnace, depending on the volume of high temperature zone and furnace structure) furnace temperature uniformity (+10 C), temperature control accuracy (+1 C).
Low energy consumption: double-layer alumina insulation material, good thermal insulation and refractory effect, low heat loss, fast heating. :
The service life of vulnerable parts is long: the bottom of crucible is padded with high-strength hard composite felt to ensure that the graphite crucible is flat and uniformly stressed at high temperature, which is 1.3 times the service life of similar products.
High safety: exclusive design of furnace body explosion-proof valve, safe and reliable.
Highly automated equipment
1. Full-automatic control, intuitive display of various parameters data on touch screen, perfect alarm and shutdown protection device. Water and electricity automatic control, easy to operate.
2. The power cabinet adopts fully sealed structure. The cabinet is equipped with water-cooled and air-cooled radiators. It does not exchange heat with the outside air. The advanced temperature control system adopts imported digital display intelligent temperature control meter. It can communicate with PLC and complete the temperature measurement and control process automatically and accurately. The system can raise temperature according to the given heating curve and store 20 heating curves of 400 different processes.
3. Closed internal circulation pure water cooling system and digital flow monitoring system are adopted, each water is protected by flowmeter monitoring.
4. The high performance gas purifier developed and produced by CAS can reduce the oxygen content of gas to 1PPMV and the dew point temperature to -70 C.
5. Furnace body conversion adopts our company's special high-performance IF converter to avoid the bad contact phenomena such as the traditional contactor's ignition.
6. According to the heating time and technological requirements, a single power supply cabinet can be equipped with multiple furnace bodies, and the heating and cooling of a single furnace body can be accomplished separately, which greatly improves the production efficiency.
