Claims (1)

Способ производства офлюсованного агломерата из руд и тонкоизмельченных концентратов, включающий дозирование компонентов агломерационной шихты, их смешивание, подогрев и окомкование, а также спекание гранулированной шихты, отличающийся тем, что в шихте обеспечивают значение модуля микроструктуры (Feобщ·СаО)/(Fe+2·SiO2) в пределах 7-16, при этом осуществляют увлажнение агломерационной шихты последовательно в три стадии: при ее смешивании в смесителе - первая стадия, в первой трети длины окомкователя от места загрузки шихты - вторая стадия и во второй трети длины окомкователя - третья стадия, причем переокомкованную часть шихты разрушают механическими средствами или при обработке всей шихты на участке окомкователя в водопадном режиме ее движения, а подогрев окомкованной шихты производят до температуры меньшей температуры точки росы на 10-15°.A method for the production of fluxed agglomerate from ores and finely divided concentrates, including dosing the components of the sinter charge, mixing, heating and pelletizing, and also sintering the granulated charge, characterized in that the charge provides the value of the microstructure module (Fe total · CaO) / (Fe +2 · SiO 2 ) in the range of 7-16, while the sintering mixture is moistened sequentially in three stages: when it is mixed in a mixer, the first stage, in the first third of the length of the pelletizer from the charge loading site, the second stage and in the second third of the length of the pelletizer, the third stage, and the re-bonded part of the charge is destroyed by mechanical means or when the entire charge is processed in the pelletizer in the waterfall mode of its movement, and the pelletized mixture is heated to a temperature of 10-15 ° lower than the dew point temperature.
