1. Process for making pip iron, wherein iron ore is reduced in a reduction shaft-type furnace and the sponge-iron thereby obtained is them melted in a melt-down gasifier, a carbon carrier and a reducing gaz being introduced into the melt-down gasifier and the gas produced in the melt-down gasifier being channelled as reducing gas in the reduction shaft furnace, characterized in that the oxidised components CO2 and H2 O are at least partially liberated from the top gas of the reduction shaft furnace (1) and the top gas prepared in this manner is conducted into the melt-down gasifier (2). |
