    • 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reducing gas is produced which is injected into reduction zones of the reduction stages (1, 2), is reacted there, is withdrawn as a top gas and optionally is supplied to a consumer.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).
    • 在生产液体生铁943）或含铁矿石（5）和助熔剂的物料的液态钢产品的过程中，至少部分含有一部分细粉，铁矿石直接还原成海绵铁 通过流化床法将至少两个还原阶段（1,2），海绵铁在碳载体和含氧气体的供应下在熔化气化区（39）中熔化，并且CO-和H 2 - 产生含有还原气体的废气，其被注入到还原段（1,2）的还原区中，在其中反应，作为顶部气体排出并任选地供应给消费者。 为了在最佳利用还原气体的情况下实现铁矿石的均匀还原，通过还原气体将第一还原段（1）中的铁矿石（5）分级成至少两个具有不同粒度分布的级分， 在分离的流化床（6,15）中每个馏分被还原气体还原，其中还原气体保持含有粗晶粒部分的第一流化床（6），并将细晶粒部分与其分离，其中 进一步地，将还原气体另外引入到另外的流化床（15）中，直接还原的铁矿石（5）从第一流化床（6,15）和另外的流化床（6,15）排出，并且精细和粗颗粒馏分 在与第一还原阶段（1）相同的方式和从最后的还原阶段（2）操作的至少一个另外的还原阶段（2）中，第一还原阶段（1）中的还原进一步减少，细晶粒分数为 引入熔化 气化区（39），同时通过提供氧气而聚集，并且粗粒部分重力地直接进入熔化气化区（39）。 1）。
