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： 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 method for producing liquid pig iron (9) or steel pre-products from fine-particulate iron-containing material (4) in a melter gasifier (1), the iron-containing material (4) is melted in a bed of solid carbon carriers (2) under supply of carbon-containing material (2) and oxygen-containing gas, at the simultaneous formation of a reducing gas, wherein the fine-particulate reduced material (4) and oxygen are introduced into the bed (20, 21) from the side. To be able to charge the fine-particulate iron-containing material to the melter gasifier (1) without a need for briquetting and, in doing so, avoid discharging of the fine-particulate iron-containing material (4) by the reducing gas formed in the melter gasifier (1), a fluidized bed (21) of fine-particulate solid carbon carriers (2) and fine-particulate iron-containing reduced material (4) is maintained above a fixed bed (20) formed of solid carbon carriers (2) and the fine-particulate reduced material (4) is charged into the fluidized bed (21) directly, in immediate contact with oxygen, preferably in the form of a strand having a ring-shaped cross-section and peripherally surrounding an oxygen jet and enclosing the oxygen, such that the oxygen is enclosed by the supplied fine-particulate reduced material (4), and the fine-particulate reduced material (4) is melted in the fluidized bed (FIG. 1).

摘要： With a method for producing liquid metal from charging substances containing ore and of fluxes, the ore is directly reduced to sponge metal in at least one reduction zone (5, 7, 8), the sponge metal is melted along with fluxes in a melt-down gasifying zone (11) under the supply of carbon carriers and an oxygen-containing gas. A CO- and H2-containing process gas serving as a reducing gas is produced, fed into the reduction zone (5, 7, 8), reacted there, and subsequently withdrawn, wherein slagforming fluxes, in particular calcium carbonate, dolomite etc., gas are calcined by the process gas in a calcining zone (26′) that is separate from the reduction zone (5, 7, 8) and melt-down zone (11). To be able to employ slagforming fluxes of any desired grain and without disturbances of the reduction process, the calcining zone (26′) is connected in parallel to the reduction zone (5, 7, 8) with respect to the material flow and the calcined fluxes are fed into the melter gasifier (10) directly.

摘要： In a method of charging metal carriers which contain a portion of fines and are at least partially reduced and carbon carriers to a melter gasifier (10) in which a melt-down gasifying zone (11) is maintained, the metal carriers and the carbon carriers are fed into the melter gasifier (10) above the level of the melt-down gasifying zone (11) and descend to the melt-down gasifying zone (11) and travel through the same forming a metal melt and producing a reducing gas by coal gasification. In order to prevent a partial discharge of the metal carriers from the melter gasifier (10) during the charging of the same and to be able to achieve uniform distribution of the carbon carriers and the metal carriers, both the carbon carriers and the metal carriers are introduced into the melter gasifier centrally above the melt-down gasifying zone (11), preferably gravitationally, with a central strand (32) of metal carriers being formed which is peripherally surrounded by a jacket strand (37) formed by the carbon carriers.

摘要： In a method of producing molten pig iron (9) or steel pre-products from lump ore which in at least one reduction zone is reduced to partially and/or completely reduced sponge iron (4) in a shaft furnace, the sponge iron (4) is melted down in a melt-down gasifying zone (8) of a melter gasifier (1) under supply of carbon-containing material (2) and oxygen and while simultaneously forming a reducing gas. To ensure that there will be a specific gap volume in the bed (13) of solid carbon carriers (2) even when charging fine-particle sponge iron (14) and hence that the bed (13) of solid carbon carriers (2) will be thoroughly flown through by gas, at least the sponge iron (4) is charged to the melt-down gasifying zone (8) discontinually, under formation of areas (14) of piled-up sponge iron which are embedded in the bed (13) of carbon carriers (2) and which are superposed and which are separated by solid carbon carriers (2), wherein each of the areas (14) of piled-up sponge iron while sparing a cross section zone (15) of the melt-down gasifying zone (8) extends over the cross section of the same and wherein the reducing gas forming the melt-down gasifying zone (8) flows past the areas (14) of piled-up sponge iron under melting of the same and upwards through the cross section zones (15) that are free from sponge iron and formed from carbon carriers (2), and flows through these zones.
