在一个或多个减速单元，提出用于从粉矿生产生铁的方法，其中所述细矿石预还原（1，2）。 兹所得海绵铁是随后在使用至少一个等离子体焰炬（9）熔化气化器（3）和固体碳质还原剂被熔化并最终还原。 海绵铁是通过等离子炬供给到熔融气化器中的等离子体焰炬的区域的下段，优选直接，累积熔体和炉渣上方。 所需的为完全还原固体含碳材料，特别是低等级的煤，从顶部（18）被输入到熔炉。 它被转换在该焦炭并在熔化气化器的下部形成，流化床，其通过等离子气体另外引入氧气保持和最终减速CO产生的。

It is a process for the production of pig iron from fine ore proposed in which the fine ore is pre-reduced in one or more reduction units (1, 2). The hereby resulting sponge iron is subsequently molten and finally reduced in a melt-down gasifier (3) using at least one plasma torch (9) and a solid carbonaceous reducing agent. The sponge iron is input to the lower portion of the input schmelzver ^g milling tool in the field of plasma torch, preferably directly through the plasma torch, above the accumulating melt and slag. The for complete reduction required solid carbonaceous material, particularly low-rank coal, is entered from the top (18) into the melter gasifier. It is converted in this in coke and forming in the lower part of the melter gasifier, a fluidised bed which is maintained by the plasma gas additionally introduced oxygen and formed during the finish reduction CO.
