Показано, что приход теплоты при окислении железа и других компонентов шихты настолько значителен, что тепловой режим и технологический процесс в целом приобретают признаки автогенного. Существенные потери с химическим недожогом свидетельствуют о неудовлетворительной организации аэродинамических потоков в объе ме рабочего пространства печи. С использованием компьютерной программы SolidWorks Flow simulation рассмотрены аэродинамические потоки и температурные поля в зоне нахождения холодной шихты, расположенной между электродами и внутренней поверхностью стены печи. Рекомендован рациональный способ установки газокислородных горелок, фурм подачи кислорода и эжекторов для ввода углеродсодержащих материалов в ванну печи.</p></abstract><trans-abstract xml:lang="en"><p>The paper presents the results of the design study of the material and heat balance on the existing furnace EAF-120 of company «Danieli». It is shown that the arrival of the heat in the oxidation of iron and other components of the charge is signifi cant, and the thermal regime and the whole process become signs of autogenous process. Signifi cant loss of chemical underburning indicate unsatisfactory organization of aerodynamic fl ows in the amount of working space of the furnace. Using a computer program SolidWorks Flow simulation the aerodynamic fl ow and the temperature fi eld in the cold charge location disposed between the electrodes and the inner wall surface of the furnace has been considered. The authors have recommended the rational way to install oxy-fuel burners, oxygen lances and the eductors for inputting carbonaceous material into the bath of the furnace.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>печь</kwd><kwd>дуга</kwd><kwd>сталь</kwd><kwd>металл</kwd><kwd>шихта</kwd><kwd>природный газ</kwd><kwd>кислород</kwd><kwd>горелка</kwd><kwd>фурма</kwd><kwd>факел</kwd><kwd>углерод</kwd><kwd>электрод</kwd><kwd>свод</kwd><kwd>стена</kwd></kwd-group><kwd-group xml:lang="en"><kwd>furnace</kwd><kwd>arc</kwd><kwd>steel</kwd><kwd>metal</kwd><kwd>charge</kwd><kwd>natural gas</kwd><kwd>oxygen</kwd><kwd>burner lance</kwd><kwd>torch</kwd><kwd>carbon electrode</kwd><kwd>vault</kwd><kwd>wall</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Worldsteel Association Steel Statistical Yearbook 2011. – Brussels: Worldsteel Committee on Economic Studies, 2011. – 120 p.</mixed-citation><mixed-citation xml:lang="en">Worldsteel Association Steel Statistical Yearbook 2011.
