VERFAHREN UND ANLAGE ZUR DIREKTEN ERZEUGUNG VON EISENSCHWAMMPARTIKELN UND FLUESSIGEM ROHEISEN AUS STUECKIGEM EISENERZ

摘要

In a process for the direct production of sponge iron particles and liquid crude iron from iron ore in lump form, which is reduced in a direct reduction unit and fed in a hot condition to a melting gasifier, the sponge iron particles which are discharged from the direct reduction unit are separated into a fine grain fraction and a coarse grain fraction, and only the fine grain fraction is fed to the melting gasifier. That ensures economy of operation, without an excess of gas.
