摘要： In the process for the production of liquid pig iron 943) or liquid steel pre-products from charging substances comprising iron ore (5) and fluxes and at least partially containing a portion of fines, the iron ore is directly reduced to sponge iron in at least two reduction stages (1, 2) by the fluidized bed method, the sponge iron is melted in a melt-down gasifying zone (39) under the supply of carbon carriers and an oxygen-containing gas, and a CO- and H2-containing reducing gas is produced which is injected into reduction zones of the reduction stages (1, 2), is reacted there, is withdrawn as a top gas and optionally is supplied to a consumer. To achieve uniform reduction of the iron ore at optimum exploitation of the reducing gas, the iron ore (5) in a first reduction stage (1) by aid of the reducing gas is fractionated into at least two fractions having different grain size distributions each, each fraction is reduced by the reducing gas in a separate fluidized bed (6, 15), wherein the reducing gas maintains a first fluidized bed (6) containing the coarse-grain fraction and separates the fine-grain fraction from the same, and wherein, further, reducing gas is additionally introduced into the further fluidized bed (15) directly reduced iron ore (5) is discharged both from the first and from the further fluidized bed (6, 15) and the fine- and the coarse-grain fraction reduced in the first reduction stage (1) are further reduced in at least one further reduction stage (2) operating in the same manner as the first reduction stage (1) and from the last reduction stage (2) the fine-grain fraction is introduced into the melt-down gasifying zone (39) while being agglomerated by provision of oxygen, and the coarse-grain fraction is fed directly into the melt-down gasifying zone (39) gravitationally (FIG. 1).

摘要： In 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.

摘要： In a method for treating particulate material in the fluidized bed method, the particulate material is maintained in a fluidized bed by a treating gas flowing from bottom to top and thereby is treated. To minimize the consumption of treating gas and to reduce entrainment of fine particles by the treating gas, a particulate material having a wide grain distribution and a relatively high portion of fines is used for treatment and the treating gas in the fluidized bed is maintained at a superficial velocity less than the velocity required for fluidizing the largest particles of said particulate material.

摘要： In a process for producing molten pig iron or liquid steel pre-products, from particulate iron-oxide-containing material by fluidization, the iron-oxide-containing material is prereduced in at least one prereduction stage (7) by aid of a reducing gas and subsequently is reduced to sponge iron in a final reduction stage (8), the sponge iron is melted in a meltdown-gasifying zone (11) under the supply of carbon carriers and an oxygen-containing gas, and a CO- and H.sub.2 -containing reducing gas is produced which is introduced into the final reduction stage (8), is reacted there, is drawn off, subsequently is introduced into a prereduction stage (7), is reacted there, is drawn off, subjected to scrubbing and subsequently is carried off as an export gas and wherein at least a portion of the reacted reducing gas is purified from CO.sub.2, is heated and is used as a recycle-reducing gas for the reduction of the iron-oxide-containing material. To ensure reduction while avoiding the occurrence of "sticking", while also minimizing the amount of carbon carriers charged, a portion of the reducing gas flowing from the final reduction stage (8) into the prereduction stage (7) is branched off, washed, purified from CO.sub.2 and heated and subsequently is recycled to the final reduction stage (8) (FIG. 1).

摘要： There is disclosed a method of starting a plant for the production of pig iron or steel pre-material including a direct-reduction shaft furnace and a meltdown gasifier.At first the still empty meltdown gasifier is heated up by aid of a combustible gas and the smoke gases forming are introduced into the still empty direct-reduction shaft furnace.Coke or a degassed coal product is charged into the direct-reduction shaft furnace and the smoke gases introduced into the direct-reduction shaft furnace are passed through the coke or the degassed coal product by releasing their sensible heat.The coke or the degassed coal product thereby is heated to ignition temperature and is charged into the meltdown gasifier in the hot state, catching fire upon the injection of an oxygen-containing gas or of oxygen.A further coal or coke bed serving for gasification is charged on the ignited bed of coke or degassed coal product and the charging substances are charged into the direct-reduction shaft furnace.
