Vertical high temperature graphitising furnace

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.

Product Parameter

Product Characteristics

-  3000 ℃, commonly used temperature 2900 ℃.
