Твердофазное восстановление проводили при температурах 850 и 1000 °С в атмосфере оксида углерода СО и в смеси с твердым углеродом. Распределение железа и фосфора исследовано с помощью электронного сканирующего микроскопа. Установлено, что при температуре 1000 °С минимальное количество фосфора (до 0,3 %) переходит в металлическую фазу при восстановлении оксидом углерода СО. При восстановлении в смеси руды с углеродом содержание фосфора в металлической фазе достигает 1,0 – 1,3 % даже при 850 °С. Проведено термодинамическое моделирование процессов при восстановительном обжиге оолитовой руды в зависимости от температуры (1000 – 1400 К) и количества углерода в системе. Показано, что температура восстановления и степень восстановления фосфора меняются в зависимости от соотношения CO и CO2 в газовой фазе. При температуре меньше 892 °С фосфор не восстанавливается, а все железо находится в металлической фазе. С увеличением количества углерода в системе в металлической фазе появляется фосфор. При избытке углерода в системе весь фосфор находится в металлической фазе уже при 892 °С. Таким образом, при определенном количестве углерода в системе и, соответственно, при определенном соотношении CO и CO2 в составе газовой фазы возможно селективное восстановление железа без восстановления фосфора даже при температуре 1100 °С. Сравнение экспериментальных результатов с результатами термодинамического расчета подтверждает возможность селективного восстановления железа без восстановления фосфора только оксидом углерода СО.</p></abstract><trans-abstract xml:lang="en"><p>Possibility of selective solid-phase reduction of iron from oolitic ore has been experimentally confirmed. Solid phase reduction was carried out at temperatures of 850 and 1000 °C in CO atmosphere and in the mixture with solid carbon. Distribution of iron and phosphorus was investigated with scanning electron microscope. It was found that at temperature of 1000 °C minimum amount of phosphorus (up to 0.3 %) is transformed into the metallic phase at reduction by carbon monoxide. Upon reduction in mixture of ore with carbon, phosphorus content in metal phase reaches 1.0 – 1.3 % evenat temperature of 850 °C. Thermodynamic modeling of the processes occurring during reductive roasting of oolitic ore was carried out depending on temperature (1000 – 1400 K) and amount of carbon in the system. It is shown that reduction temperature and degree of phosphorus reduction vary depending on ratio of CO and CO2 in the gas phase. At temperatures below 892 °C, phosphorus is not reduced and all iron is in metal phase. With an increase in amount of carbon in the system, phosphorus appears in metal phase. With an excess of carbon in the system, all phosphorus is in metal phase at temperature of 892 °С. Thus, with a certain amount of carbon in the system and, correspondingly, with a certain ratio of CO and CO2 in gas phase, selective reduction of iron is possible without phosphorus reduction even at temperature of 1100 °С. Comparison of experimental results with results of thermodynamic calculation confirms possibility of se selective reduction of iron without phosphorus reduction only by carbon monoxide.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>оолитовая руда</kwd><kwd>селективное восстановление</kwd><kwd>металлизация</kwd><kwd>восстановление фосфора</kwd><kwd>степень восстановления</kwd><kwd>температура восстановления</kwd><kwd>термодинамическое моделирование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>oolitic ore</kwd><kwd>selective reduction</kwd><kwd>metallization</kwd><kwd>phosphorus reduction</kwd><kwd>reduction degree</kwd><kwd>reduction temperature</kwd><kwd>thermodynamic modeling</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">Металлургия чугуна / Е.Ф.
