Direct reduction device to obtain metal iron with a high content of carbon in the form of carbide

摘要

A direct reduction device (10) of the gravitational type to obtain iron carbide starting from iron oxide, comprising a reduction and carburation reactor (12) below which a cooling and passivation container (26) is arranged wherein the iron carbide is suitable to be cooled and passivated, between the reactor (12) and the container (26) a valve for solids (24) is interposed suitable to regulate the transfer of the iron carbide.
