ABSTRACT Process for producing pigiron A process for producing pigiron is described involving the use of a reduction shaft furnace 1 and a melt-down gasifier 2. The sponge iron produced from iron ore in the reduction shaft furnace is fed into the melt-down gasifier and converted into a pigirion melt. The gas produced in the melt-down gasifier is passed as reducing gas into the reduction shaft furnace both via a cyclone separator 11 and a line 12 and directly via a line 13. The blast furnace gas leaving the reduction shaft furnace, after passing through a scrubber 4, is largely returned via a CO2 scrubber 6, in which CO2 and H20 are removed from the blast furnace gas, in such a way that it can be used for forming the reducing gas in the melt-down gasifier and also as a cooling gas for the reducing gas produced in said gasifier.
