Abstract
An integrated process for continuously making iron-containing materials is provided in which a finely-divided iron ore is at least partially reduced in a staged fluidized iron ore reduction process and subsequently transferred and further treated in a melting zone. A carbonaceous fuel and oxygen are reacted in the melting zone to generate sufficient heat to melt the added prereduced ore and also to generate a reducing gas rich in CO which is used to fluidize and prereduce the iron ore in the reduction zone. A carbonaceous fuel is mixed with the iron bearing material in the last stage of the reduction process to provide for absorption of excess heat from the hot reducing gases which are generated in the melting zone.
