FURNACE FOR CONTINUOUSLY GRAPHITIZING CARBON FIBER

摘要

This furnace (1) for continuously graphitizing a carbon fiber is provided with: a supply unit (2) that supplies an object to be treated (W) comprising a carbon fiber; a chamber (3) that graphitizes the object to be treated (W) that is supplied from the supply unit (2); and a recovery unit (4) that recovers the object to be treated (W) that is discharged from the chamber (3) after graphitization. The chamber (3) comprises a preheating zone (7) that preheats the supplied object to be treated (W) and an electric heating zone (8) that applies electricity to and heats the preheated object to be treated (W). The electric heating zone (8) comprises: a pair of electric rolls (11) across which the preheated object to be treated (W) is strung and travels; and a DC power source (13) that is connected to the pair of electric rolls (11) and that causes current to flow between the pair of electric rolls (11) via the preheated object to be treated (W) that is strung between the pair of electrical rolls (11).
