Claims (1)

Предлагается способ получения жидкого чугуна из железных руд и сырьевых материалов, имеющих, по меньшей мере, частично мелкозернистую фракцию, образующую присадки, причем сырьевые материалы восстанавливают непосредственно до губчатого железа в одной, по меньшей мере, восстановительной зоне, губчатое железо расплавляют в зоне (I-IV) плавильного газификатора с подводом носителей углерода и кислородсодержащего газа и получают газ восстановитель, который подводят в зону восстановления, там повергают химическому превращению и отводят в виде газа, готового к употреблению, этот способ в значительной мере улучшен, благодаря чему становится экономичным применение мелкозернистой руды. Это обеспечивается за счет того, что преимущественно гаматитные и/или магнетитные мелкозернистые руды и/или рудную пыль подвергают в зоне предварительного нагрева подогреву в псевдоожиженном слое, подогретые таким образом сырьевые материалы в значительной мере окончательно восстанавливают в одной, по меньший мере, присоединенной зоне восстановления с применением псевдоожиженного слоя, после чего сырьевые материалы загружают с помощью принудительной подачи в жидкий спой (II-III) зоны (I-IV) плавильного газификатора и там расплавляют.A method is proposed for producing molten iron from iron ores and raw materials having at least partially a fine-grained fraction forming additives, the raw materials being reduced directly to sponge iron in one at least a reducing zone, sponge iron is melted in zone (I -IV) a melting gasifier with a supply of carbon carriers and an oxygen-containing gas, and a reducing gas is obtained, which is supplied to the reduction zone, there they are subjected to chemical transformation and discharged in the form gas, ready-to-use, this method is significantly improved, due to which it becomes economical to use fine-grained ore. This is due to the fact that predominantly gamatite and / or magnetite fine-grained ores and / or ore dust are subjected to preheating in the fluidized bed, the raw materials heated in this way are substantially completely restored in one, at least connected reduction zone using a fluidized bed, after which the raw materials are loaded by forced feeding into the liquid sump (II-III) of the zone (I-IV) of the melter gasifier and melted there.
