      <abstract xml:lang="ru">
        <p>Россия является одним из мировых лидеров по производству стали, при этом около 33 % производства приходится на переплавку лома в дуговых сталеплавильных печах. Для работы при высоких токовых нагрузках и температуре в печах применяются графитированные электроды марок SHP и UHP, которые в основном состоят из игольчатого кокса. Производство игольчатого кокса сосредоточено в США, Японии, Корее и Китае, где в качестве сырья используют побочные продукты металлургических и нефтеперерабатывающих предприятий – угольное (смолу и пек) и нефтяное (декантойль). В России ежегодная потребность в игольчатом коксе составляет около 100 тыс. т, однако вся она удовлетворяется посредством импорта. Сырьевой потенциал России, установленный авторами статьи, составляет более 5 млн т в год и включает декантойль, каменноугольные смолу и пек, а также тяжелую смолу пиролиза. Описаны результаты получения игольчатого кокса из декантойля и тяжелой смолы пиролиза. Наработка опытных образцов игольчатого кокса проводилась на специально разработанных лабораторных установках замедленного коксования (загрузкой до 0,25 и 80 кг). Сырье было модифицировано по оригинальной технологии Санкт-Петербургского горного университета, сходимость целевых свойств которой подтверждается результатами анализа качества полученных игольчатых коксов, в том числе и после 100-кратного масштабирования. Из полученного кокса были сформованы электроды. После стандартизированных стадий обжига, механической обработки и графитации при 2800-3000 °С коэффициент линейного термического расширения составил менее 1 × 10–6 К–1, а значение удельного электрического сопротивления 7,1-7,4 мкОм, что доказывает, что полученный углеродный материал соответствует по качеству японским аналогам и игольчатому коксу марки Super Premium.</p>

      <abstract xml:lang="en">
        <p>Russia is one of the world's leading steel producers, while about 33 % of production comes from the scrap remelted in arc steelmaking furnaces. The graphitized electrodes of SHP and UHP grades, mainly consisting of needle coke, are used for high current loads and temperatures in furnaces. USA, Japan, Korea, and China are focused on needle coke production, where coal (tar and pitch) and petroleum (decantoil), by-products of metallurgical factories and oil refineries, are used as raw materials. Russia's annual demand for needle coke is approximately 100 thousand tons, but all of it is covered by imports. Russia's raw material potential, established by the authors of the article, is more than 5 million tons per year and includes decantoil, coal tar and pitch, and heavy pyrolysis tar. The results of obtaining needle coke from decantoil and heavy pyrolysis tar are given below. The prototypes of needle coke were produced on specially designed delayed coking laboratory units (loading up to 0.25 and 80 kg). Raw materials were modified according to the original technology of Saint Petersburg Mining University, the convergence of target properties of which is confirmed by the results of quality analysis of the obtained needle coke, including after 100-fold scaling. The electrodes were molded from the obtained coke. After standardized stages of firing, mechanical processing and graphitization at 2,800-3,000 °C, the coefficient of linear thermal expansion was less than 1 × 10–6 К–1, and the value of specific electrical resistance was 7.1-7.4 μOhm, which proves that the obtained carbon material corresponds in quality to Japanese analogues and Super Premium needle coke.</p>
