Publication number: 20210246521Abstract: The invention relates to a process for producing carburized directly reduced iron sponge from iron oxide material. Firstly, direct reduction is carried out by means of a reduction gas consisting at least predominantly of H2 and the carbon content in the iron sponge is then increased by means of a carburizing gas which is fed in, after which used carburizing gas is at least partly taken off while largely avoiding mixing with the reduction gas.
