Blast furnace process tecscience
The unmelted iron ores still contain nonreduced iron oxides. An unfavourable accumulation of ores at the contact points can also make gas flow difficult and thus leave nonreduced iron ore behind. At the latest, however, when the melting process occurs in the deeper and hotter zones of the blast furnace, iron ores can bepletely reduced.
