ELECTRIC FURNACE FOR GRAPHITIZATION

摘要

PROBLEM TO BE SOLVED: To improve the durabilities of electrodes and supporting parts to hold and to insulate the electrodes by suppressing their thermal degradation to a minimum. SOLUTION: Plural sets of the electrodes 9a and 9b opposingly set between a carbon powder feed opening 4 and a graphite powder recovery port 7 in a furnace body 1 with a graphitization zone 8 between are installed so as to at least partially face to the interior of the furnace body 1, an electric current can be sent with staggering the timings of each set of the electrodes 9a and 9b. The electrodes 9a and 9b are attached to the inner ends of a heat transfer member 12 passing through the inside and outside of the furnace body 1 and the heat transfer member 12 can be cooled from its outer ends.
