Claims (1)

Способ агломерации с рециркуляцией отходящих газов, включающий отбор части отходящих газов, смешивание их с воздухом, подачу смеси газов на агломашину через специальный колпак, спекание при просасывании через слой газовой смеси, отличающийся тем, что, с целью сокращения выбросов вредных веществ в атмосферу, улучшения качества агломерата и снижения тепловых затрат на его производство, на аглоленте формируют зону частичного охлаждения аглоспека, рециркулирующий газ получают путем смешивания газов зоны спекания и зоны частичного охлаждения, а полученный рециркулянт распределяют по зоне спекания и по зоне охлаждения, при этом процесс охлаждения ведут таким образом, чтобы максимальная температура спека, сходящего с аглоленты составляла 0,6 - 0,7 температуры начала его плавления.A method of agglomeration with recirculation of exhaust gases, including the selection of part of the exhaust gases, mixing them with air, supplying a mixture of gases to the sinter machine through a special cap, sintering when sucking through a layer of a gas mixture, characterized in that, in order to reduce emissions of harmful substances into the atmosphere, improve the quality of the sinter and reduce the heat costs of its production, on the sinter strip form a zone of partial cooling of sinter, recycle gas is obtained by mixing the gases of the sintering zone and the zone of partial cooling Ia, the resulting retsirkulyant partitioned by sintering zone and cooling zone, the cooling process is carried out so that the maximum temperature of the cake coming down from aglolenty was 0.6 - 0.7 of its melting start temperature.
