<p>A method for reducing particulate iron oxide (24) and/or other iron units to molten iron (26) utilizing natural gas (17) as the source for process heat and reduction potential, in which the ore freely falls during the melting and reduction process. Reducing gas (22) and iron oxide (24) are carried through the process in a generally counterflow relationship. Heat for melting and reduction is generally supplied by combusting a fraction of the reductant gas (22) with oxygen (23) or air. Heat may also be supplied through electric arc heating.</p> |
