Method and device for producing pig iron

A method for reducing material containing iron oxide, comprising:

• providing material containing iron oxide for forming a solid bed in a reduction shaft;
• converting the material containing iron oxide to pre-reduced material in the reduction shaft by introducing at least one pre-reduction gas into the solid bed at a pressure p1;
• also introducing at least a part of the pre-reduced material from the reduction shaft into a melter gasifier and there finally reducing the pre-reduced material by a reduction gas under a pressure p2 formed in the melter gasifier;
• diverting a top gas having a pressure p3 out of a chamber above the solid bed in the reduction shaft, the diversion being out of the reduction shaft;
• diverting dust exhaust gas having a pressure p4 from the solid bed and out of the reduction shaft;
• wherein there are at the reduction shaft relationships p1>p4 and p1>p3;
• and
• guiding at least part of the dust exhaust gas jointly with the pre-reduced material at least along a part of a path traveled by the pre-reduced material on introduction thereof into the melter gasifier from the reduction shaft to the melter gasifier.
