VGCF vapor grown carbon fiber high temperature purification Graphitization Furnace 3000 degree Keep warm for 2 hours
The Extreme Temperature Graphitization furnaces use medium frequency induction heating method. A water cooled induction coil installed inside the furnace. At the center of the coil, there is a graphite crucible as the susceptor for the induction current, surrounded by carbon felt as the insulation material.
CX-GF series are front loading batch type induction heating furnaces with round or cubic hot zone shape. Cubic hot zones are specially designed for clients who are not satisfied with round hot zones due to some reasons such as dead space.
Maximum operating temperature of 3000°C can meet all demands in carbon material’s graphitization treatment.
Horizontal design of these series, features simple working principle compared to vertical series. The main advantages of horizontal design are easy loading/unloading, easy clean-up of furnace inside, simple operation and maintenance for workers, and easy replacement of consumable spare parts.
Main Application:
Graphitization treatment of Carbon materials and Heat Conductive materials, like synthetic graphite film (Polyimide Graphite film, abbreviated PI film), C/C Composites materials, Graphene, Lithium Battery Negative Electrode Materials, Carbon Fiber and Carbon fiber ropes, etc. Purification and Graphitization process of nature graphite and synthetic graphite. Purification and De-ironing process of Carbon Nanotube (CNT). Sintering of high temperature ceramics, other materials which can be sintered or heated in graphite hot zone (carbon included environment).
