The new technology of continuous graphitization petroleum coke in electric shaft furnaces continuous operation was developed. This development provides, compared to the current technology, reducing the specific energy consumption by 1.5 times with an increase in the quality of the finished product by 5-10% by increasing the homogeneity of its physical properties and has no analogues in Ukraine. At the development of new technology have been substantiated benefits of shaft furnace to a continuous process graphitization of petroleum coke, instead of using classical technology of filler in the manufacture of electrodes. The new technology are to provide reduce of quantity stages of the technology cycle and expenditure of energy. The physical and mathematical model of graphitizing petroleum coke in the single-phase electric furnace continuous operation were developed, based on a coupled system of differential equations using Eulerian models and thermoelectric state to allow a theoretical study of the physical fields in direct of graphitization petroleum coke production. A developed mathematical model to permit define operating of practice for receipt the final product. Completed the development of appropriate software and test it conducted. The technique and studies of electrical resistivity of petroleum coke in a wide range of temperatures and pressures. Developed conceptual designs of modernized designs of electric are made, designed for continuous graphitization of petroleum coke. Based on the studies, a preliminary design of the modernized shaft furnace and production of schedules starting and running modes graphitizing of petroleum coke were developed, that achieve the required level of temperature and holding at this temperature for a certain time in advance. Results have been implemented in production.
