The present invention relates to a method of reducing the material containing iron oxide, the material containing iron oxide is a material containing iron oxide to form a solid layer in the reducing furnace is at least one pre-reducing gas is introduced at a pressure (p1) into a solid layer by is converted into the pre-reduction material in the reducing furnace. The pre least one portion of reduced material, preferably of the entire pre-reduced material is introduced into the melter-gasifier is pre-reduced material by a reducing gas at a pressure (p2) from the reducing furnace is finally reduced. Exposed pressure gas having the (p3) and a switch out of the upper solid layer out of the reducing chamber, at least one dust exhaust gas having a pressure (p4) is switched out of the reducing furnace from a solid layer. The relationship p1> p4 and p1> p3 is applied, is preferably also subject to p4> p3. The invention also relates to a device for executing this method.
