Abstract

The invention discloses a radio-frequency heating carbon fiber graphitization continuous batching production system and a radio-frequency heating carbon fiber graphitization continuous batching production method for solving the technical problem that fire striking caused by blackening of a quartz tube produces broken wires and burrs to affect the production efficiency. The invention adopts the technical scheme that: a series combination of at least two independent radio-frequency heaters is adopted in the continuous batching production system, the processed carbon fibers pass through the independent radio-frequency heaters in turn, and a multi-gear power output switch is arranged between the radio-frequency heater set and a high-frequency generator; and in the method, a group of radio-frequency heaters are connected in series in the radio-frequency heating carbon fiber graphitization process. The system and the method have the advantages of avoiding the disadvantage that the fire striking caused by the blackening of the quartz tube due to long-time use produces the broken wires and the burrs to affect the production efficiency, avoiding the phenomenon of fire striking and discharge when tar and carbon black attached to the pipe wall after long-time use are contacted with the carbon fibers, improving the industrialized production efficiency and reducing the production cost.

Description
