PCT No. PCT/AT95/00123 Sec. 371 Date Jan. 15, 1997 Sec. 102(e) Date Jan. 15, 1997 PCT Filed Jun. 20, 1995 PCT Pub. No. WO96/00304 PCT Pub. Date Jan. 4, 1996A direct reduction process is disclosed for iron-oxide-containing materials. Synthesis gas is mixed with top gas produced during direct reduction of the iron-oxide-containing materials and is used as reduction gas for directly reducing iron-oxide-containing materials. In order to avoid or reduce metal dusting caused by an increased CO content of the reduction gas with a simple technique and equipment, the CO/CO2 ratio of the reduction gas is set at a predetermined value from 1 to 3. |
