<p>PCT No. PCT/AT96/00129 Sec. 371 Date Apr. 17, 1997 Sec. 102(e) Date Apr. 17, 1997 PCT Filed Jul. 18, 1996 PCT Pub. No. WO97/04137 PCT Pub. Date Feb. 6, 1997In a process for the production of molten pig iron or steel pre-products from fine-particulate iron-cintaining material, in a meltdown-gasifying zone of a melter gasifier (1), under the supply of carbon-containing material and oxygen-containing gas at the simultaneous formation of a reducing gas, in a bed formed of sold carbon carriers, the iron-containing material is melted when passing the bed. To be able to employ a charge here up to 100% of which consist of fine ore, while reliably avoiding discharge of the supplied fine ore, a high-temperature combustion and/or gasification xzone is formed by combusting and/or gasifying carbon-containing material under direct supply of oxygen in a killing space (III) formed above the bed, into which high-temperature combustion and/or gasification zone the fine-particulate iron-containing material is directly introduced, wherein at least incipient surface melting of the iron-containing material and agglomeration of the same are carried out by means of the heat released during the reaction of the carbon-containing material.</p> |
