Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation of graphitization furnaces, in particular to a heat dissipation device of an inner-string graphitization furnace. Background Art

[0002] The internal string graphitization furnace is a graphitization device with an appearance similar to a "big box". It is a furnace for producing artificial graphite negative electrode. The graphite negative electrode is provided with a cover plate and a post-coke insulation layer. Graphitization treatment can be carried out directly in the box without a crucible. It is a derivative device of the Acheson graphitization furnace and has the advantages of large single furnace processing capacity (100 tons) and low cost.
