ELECTRIC FURNACE FOR GRAPHITIZATION |
摘要 |
PROBLEM TO BE SOLVED: To sufficiently concentrate heat at the central part of a furnace body even in the case of using short electrodes, in time of the accident of one electrode, to utilize the other electrode connected in the same potential to the electrode and to make an electric current flow to an electrode opposed to the electrode. SOLUTION: Plural sets of 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 is sent with staggering the timings of the sets of the electrodes 9a and 9b. The plural sets of the electrodes 9a and 9b are constituted of plural sets of plural short electrodes 9a-1 to 9a-3 which are arranged in the vertical direction in the furnace body 1 and mutually electrically connected and plural short electrodes 9b-1 to 9b-3 which are opposed to them and electrically connected with forming one set from the two electrodes. |
