Novel graphitization method for large-size isostatic pressing round roasted product

The invention discloses a novel graphitization method for a large-size isostatic pressing round roasted product. The novel graphitization method comprises the following steps: step 1, adding heat preservation layers to the inner sides of furnace walls on two sides; step 2, putting a large-size isostatic pressing round roasted product into a furnace, and directly vertically placing the product; step 3, filling a filler into the furnace; step 4, paving a layer of large-size isostatic pressing round roasted product on the upper surface of the filler again; step five, paving a layer of large-sizeisostatic pressing round roasted product on the upper surface of the second layer of the filler again; step six, contacting a conductive electrode that penetrates through the furnace body with the filler; step 7, starting the conductive electrode; and step 8, after graphitization is finished, taking out and transferring the product by a worker. According to the novel graphitization method, a large-size isostatic pressing
