Abstract
A method is disclosed for the gaseous reduction of iron ore to sponge iron at a given degree of carburization and yet at a temperature suitable for hot briquetting or for direct feed to a melter or to a refining furnace. The desired percentage of carburization and the preferred elevated temperature are achieved by using a hot blend of recycled reducing gas and essentially uncracked natural gas or methane to carburize and to decrease the temperature of the sponge iron in the modifying zone of the reactor.
