Graphite electrode production process description:
Raw petroleum coke or pitch coke, after calcination at 1250/1450℃, with calcined petroleum coke or pitch coke as the aggregate, after crushing and screening, grinding, batching, adding to the kneading pan for preheating till meet the technical required temperature (corresponding to the nature of coal pitch), adding heating and melting dehydrated liquid coal pitch for kneading, and then through cooling material, pressing to make green electrodes. Green electrodes are baked under the protection of insulation material (shaped and prevent oxidation), in order to improve the strength and density of the product, if necessary, the baked product can be impregnated and burned two or three times, and then through graphitization, and finally machined into the specified size of the finished graphite electrode (Nipple).
