Method for reducing current impact through graphitized cathode electric calcination

The invention belongs to the technical field of electric calcination, and particularly relates to a method for reducing current impact in graphitized cathode electric calcination, which comprises the following steps: S1, paving a backing material on a furnace bottom by using filling coke, and raking; s2, paving an insulating material on the upper part of the backing material; s3, the roasted product is flatly placed on the upper portion of the insulating material and charged in a furnace in a channeling mode; s4, uniformly wrapping the peripheries of the roasted product and the adjusting block with an insulating material; s5, a flexible graphite pad is inserted into a gap between the adjusting block and the roasted product; s6, wrapping a layer of insulating material on the periphery of the boundary part of the adjusting block, the flexible graphite pad and the roasted product; s7, insulating plates are inserted around the roasted product in three sections in the length direction of the roasted product; and S
