With the HyREX technology, POSCO will produce direct reduced iron (DRI) by using hydrogen as reducing gas. The produced DRI will afterwards be melted in an electric smelting furnace (Smelter). The HyREX solution is directly using sinter fines and is, in that way, avoiding any agglomeration steps – like sintering or pelletizing – in advance.
