Abstract: The present disclosure relates to a process for the production of carburized sponge iron. The process comprises the steps of reducing iron ore pellets using a carbon-lean reducing gas in a direct reduction shaft reactor to provide a sponge iron intermediate; transferring the sponge iron intermediate to a carburization unit; and carburizing the sponge iron intermediate in the carburization unit using a carburizing gas to provide carburized sponge iron. The disclosure further relates to a system for the production of carburized sponge iron, a carburized sponge iron produced by the aforementioned process, and a sponge iron intermediate obtained during the production of such a carburized sponge iron.
