Vertical High Temperature Graphitising Furnace Commonly used in 3000 ℃ within the Ultra-High Temperature Furnace, used for a variety of high thermal conductivity graphite film (PI film), lithium battery anode materials, carbon materials, carbon and graphite production of carbon materials carbon, graphite; carbon fibre filament sizing graphite and other materials can be sintered in the carbon environment. This graphitization furnace working principle is different from the Acheson or internal string graphitization furnace using resistance heating or using its own heat and the use of medium-frequency heating, not in direct contact with the material to reduce the impact of graphitization of the main factors.
-??3000 ℃, commonly used temperature 2900 ℃.
-??the working atmosphere: vacuum replacement Ar2, N2 protection (micro-positive pressure)
-? temperature measurement: far-infrared optical temperature measurement temperature range 1000 ~ 3000 ℃ or 0 ~ 3000 ℃; temperature accuracy: 0.2 ~ 0.75%.
-? temperature control: programme control and manual control; temperature control accuracy: ± 1 ℃
-??Equipment adopts medium frequency power induction heating, high efficiency: unique furnace chamber design, greatly improving the furnace temperature uniformity. Limit heating speed: 200 ℃ / min (empty furnace, depending on the volume of the high-temperature zone and furnace structure) furnace temperature uniformity
-??sex ± 10 ℃, temperature control accuracy ± 1 ℃.
-?? low energy consumption: thickened alumina insulation material, heat insulation and refractory effect, heat loss is small, fast heating speed.
-??Long service life of wearing parts: 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 1.2 times of the service life of similar products.
