Graphitization furnace capable of rapidly cooling

The graphitization furnace capable of being rapidly cooled comprises a horizontally-arranged cylindrical graphitization furnace body, and heat dissipation fins are evenly distributed on the outer wall of the graphitization furnace body; a water storage tank is arranged at the bottom of the graphitization furnace body, and one side of the water storage tank is communicated with a water guide main pipe through a circulating water pump; the top end of the water guide main pipe is communicated with a first water guide branch pipe which is arranged at the upper part of the graphitization furnace body and extends along the axial direction of the graphitization furnace body, and first water outlet holes which are formed along the axis of the first water guide branch pipe are uniformly distributed in the first water guide branch pipe. Cold water in the water storage tank is lifted into the first water guide branch pipe through the water guide main pipe by virtue of the circulating pump, then discharged from the first
