Разработана новая методика исследования зоны переувлажнения в слое путем его выгрузки из спекательной чаши с сохранением структуры. Агломерационную шихту окомковывали с использованием расплава парафина вместо воды. Разрушение гранул в зонах с сухой шихтой над зоной переувлажнения образует зону мелких фракций высотой примерно 6 мм с низкой газопроницаемостью. Зона мелких фракций увеличивает потери давления в 1,4 раза и усадку слоя на 20 – 25 мм. Мелкие фракции формируют канальный ход газов в зоне переувлажнения, закупоривая каналы диам. менее 0,6 мм. Для повышения эффективности агломерационного процесса необходимо снижать негативное влияние на газопроницаемость слоя разрушения гранул в зоне сушки, интенсивного нагрева, а также в зоне переувлажнения.</p></abstract><trans-abstract xml:lang="en"><p>The process of zones formation in the layer was investigated. A new research method was developed for the saturation zone in the layer by discharge of sintering bowls with the structure conservation. Sintering mixture was pelletized using of melt paraffin instead of water. The destruction of the granules in areas with a dry charge material above the zone of saturation forms a zone of fine fractions with a height of about 6 mm with low gas permeability. Zone of fines increases the pressure loss in 1.4 times and the shrinkage of the layer – by 20–25 mm. Fines form a channel course of the gases in the zone of saturation clogging the channels with a diameter less than 0.6 mm. Negative impact on the permeability of the destruction layer of the pellets in the drying zone – intensive heating zone – and the saturation zone should be reduced to improve the efficiency of the sintering process.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>агломерация</kwd><kwd>окомкование</kwd><kwd>газопроницаемость</kwd><kwd>зона переувлажнения</kwd><kwd>усадка слоя</kwd><kwd>структура слоя</kwd><kwd>парафин</kwd><kwd>разрушение гранул</kwd></kwd-group><kwd-group xml:lang="en"><kwd>sintering</kwd><kwd>pelletizing</kwd><kwd>permeability</kwd><kwd>saturation zone</kwd><kwd>shrinkage of the layer</kwd><kwd>layer structure</kwd><kwd>paraffin</kwd><kwd>granules destruction</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">Берштейн Р.
