摘要： Provided is a reduction furnace reducing ore containing an iron oxide component, and including a charge feeding port 110 having a charge material introduced therethrough and a reducing gas intake port 170 having reducing gas injected therethrough, wherein the charge feeding port 110 is formed in an upper portion thereof and the reducing gas intake port 170 is installed in a bottom portion thereof.
According to the present invention, since the reducing gas may be injected into the center of a lower portion of the reduction furnace, the reducing gas may be allowed to be uniformly distributed in the reduction furnace, and thus, a reduction rate of the charge material may be increased and reduction rates between particles of the charge material may be uniformized.摘要翻译： 本发明提供一种含有氧化铁成分的还原炉还原矿石，其具有通过其引入的带电材料的供电口110和具有还原气体的还原气体吸入口170，其中，电荷输送口110形成在上部 其还原气体吸入口170安装在其底部。 根据本发明，由于还原气体可以被注入到还原炉的下部的中心，所以还原气体可以均匀地分布在还原炉中，因此，电荷材料的还原率 可以增加电荷材料的颗粒之间的还原速率。
