Показана их роль в формировании структуры железосодержащих брикетов. Обоснована технологическая схема получения металлургических брикетов, содержащих технологические добавки. Схема включает механическую подготовку порообразующих добавок, дозирование и первичное избирательное смешивание компонентов с получением структурных агрегатов, вторичную стадию смешивания остальной брикетируемой массы со структурными агрегатами, их вылеживание. Представлена методики проведения эксперимента и обработки экспериментальных данных. Приведены результаты исследования динамики прироста массы компонентов брикетируемой шихты в составе структурных агрегатов. Проанализированы зависимости прироста массы компонентов шихты от температуры жидкого восстановителя и технологической схемы смешивания компонентов. Проведена оценка конструкции структурных агрегатов, показана их роль в прогнозировании металлургических свойств железосодержащего сырья. Представлен анализ конструкции структурных шихтовых агрегатов на основе порообразующих добавок с различной удельной поверхностью и пористостью. Проведена оценка макро- и микроструктуры рассматриваемого материала, показана их роль в прогнозировании металлургических свойств железосодержащего сырья. Специфическая структура порообразующих добавок способна повысить функциональные возможности высокопористых материалов и создать структурные агрегаты с особыми свойствами. В процессе завершающего брикетирования эти агрегаты, обладающие первичной структурной прочностью, должны ее сохранить и сформировать прогнозируемую структуру брикета. Проанализированы дополнительные показатели, характеризующие массовые соотношения между компонентами структурных агрегатов. Приведены результаты исследования динамики прироста массы структурных агрегатов, сформированных на базовых шихтовых материалах различного фракционного состава.</p></abstract><trans-abstract xml:lang="en"><p>The functional purpose of pore-forming additives with different specific surface areas and porosities has been evaluated. Their role in the formation of the structure of iron-containing briquettes is shown. The technological scheme for the production of metallurgical briquettes containing technological additives is substantiated. The scheme includes the mechanical preparation of pore-forming additives, dosing and primary selective mixing of components to obtain structural aggregates, the secondary stage of mixing the rest of the briquetted mass with structural aggregates, and their storage. The methods of conducting the experiment and processing the experimental data are presented. The results of the study of the dynamics of the mass gain of the components of the briquetted charge in the composition of structural aggregates are presented. The dependence of the weight gain of the charge components on the temperature of the liquid reducing agent and the technological scheme of mixing the components are analyzed. The design of structural units has been evaluated, and their role in predicting the metallurgical properties of iron-containing raw materials has been shown. An analysis of the design of structural charge aggregates based on pore-forming additives with different specific surface areas and porosities is presented. The assessment of the macro- and microstructure of the material under consideration is carried out, and their role in predicting the metallurgical properties of iron-containing raw materials is shown. The specific structure of pore-forming additives can enhance the functionality of highly porous materials and create structural aggregates with special properties. During the final briquetting process, these aggregates, which have primary structural strength, must preserve it and form a predictable briquette structure. Additional indicators characterizing the mass ratios between the components of structural aggregates are analyzed. The results of a study of the dynamics of mass gain of structural aggregates formed on base-charge materials of various fractional compositions are presented.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>структурные агрегаты</kwd><kwd>прирост массы</kwd><kwd>компоненты шихты</kwd><kwd>восстановитель</kwd><kwd>порообразующие добавки</kwd><kwd>железосодержащие брикеты</kwd><kwd>технология избирательного смешивания</kwd></kwd-group><kwd-group xml:lang="en"><kwd>structural units</kwd><kwd>weight gain</kwd><kwd>charge components</kwd><kwd>reducing agent</kwd><kwd>pore-forming additives</kwd><kwd>iron-containing briquettes</kwd><kwd>selective mixing technology</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">Павловец В.М.
