    The invention relates to metallurgy, in particular, to methods for producing liquid iron or steel semi-products in a smelter gasifier. The purpose of the invention is to eliminate the re-oxidation of molten materials and reduce energy consumption. For this, in the melter gasifier 1, by adding coal and injecting oxygen-containing gas by means of the tuyere sleeves 2, a fixed bed of coke particles is blown by oxygen-containing gas, and a fluidized (boiling) layer of coke particles is formed into it and the iron-containing material is introduced into this fluidized bed. Below the fixed bed blown with oxygen-containing gas, there is a non-blown fixed bed. From the particles of coke create a fluidized bed, which is purged with a gas not containing oxygen or containing it in a small amount. 1 hp f-ly, 1 ill.

    The upper section is provided along the extreme 25 of the moving bed II; at least one pipeline 5 is installed for
    temperature above 2000 ° C; at the boundaries between fixed bed II and pseudo liquefied layer III, temperature ha

    And the resulting reducing gas “Pa” in the middle section consists of coarse coke particles immobile 11800 ° C or iron-containing temperature I and II (stationary layers) “containing particles 1200-1300 ° С, and in the re-forming melt below them p-liquid metal 6 and slag 7, while for both components it is possible to provide for the outlet. The fixed bed I does not contain a supply line, and therefore no gas is introduced into this layer. A fixed layer II is formed above the fixed layer I into which the coke particles Z are introduced by oxygen-containing gas coming from the supply pipes 2, due to which these particles are converted to carbon monoxide. Above the unsupported layer II forms a fluidized fluid layer IJI. It is supported by the reducing gas formed in the immobile layer II. Small-sized coal or coke particles remain in the zone of fluidized bed III. The particles of coal and coke, for which the gas velocity is by you, there are no conditions for the oxidation current and the pipe is insufficient, only the deposits, the reaction takes place between the hardening and collapse through the fluidized bed III and forms a fixed bed II or fixed layer I.S5 gift of which the sponge-like fixed layer II used to create heat can have a lower content necessary for conducting the process, transfer the zone of the fixed layer II - the zone of the fixed layer I - counter-current iron scrapers 1600 ° C, slag melt or molten metal lme “t temperature 1400-1500 ° C, and in the extended upper section of the melting gasifier at the upper boundary of the fluidized bed III temperature is 1500 ° Cj in the above so-called calming zone gas temperature is 1 00 ° C. The reducing gas is discharged through the discharge pipelines 5 in the amount of 1330 me (in normal conditions) per 1 ton of pig iron, while the content of the components is as follows: C 3.5, Si 0.3, S 0.1.
    In the zones of fixed layers I and II, in which, with the exception of the zone directly in front of the tuyere stockings, carbon, silicon and manganese. It is also possible to increase the carbon content in the iron melt, the benefit of carbon. A lower carbon content in the sponge gland from moving bed II is set
    temperature above 2000 ° C, at the interface between fixed bed II and fluidized bed III, the gas temperature
    1800 ° C or the temperature of the iron-containing particles is 1200-1300 ° C, and on the piles, there are no conditions for oxidation, a reaction occurs between the solid and the sponge used.
    11800 ° С or the temperature of iron-containing particles is 1200-1300 ° С, and on ponoks, there are no conditions for oxidation, there is a reaction between the fixed-sponge zone and the fixed bed zone II - the fixed-bed zone I temperature iron carriers 1600 ° C; Slag melt or molten metal lme "t temperature 1400-1500 ° C; and in the extended upper section of the melting gasifier at the upper boundary of the fluidized bed III, the temperature is 1500 ° Cj in the so-called calming zone above the gas temperature made up em 1 00 ° C. The reducing gas is discharged through the discharge pipelines 5 in the amount of 1330 Me (per normal conditions) per 1 ton of pig iron, while the content of the components is as follows: C 3.5, Si 0.3, S 0 ,one.
    In the zones of the fixed layers I and II, in which, with the exception of the zone directly in front of the tuyere arms, at 800 ° C or iron-containing particles at 1200–1300 ° C, and during interiors, there are no conditions for oxidation, what is used is sponge carbon, silicon and manganese. It is also possible to increase the carbon content in the iron melt, which can have a lower content.
    carbon carbon. The lower carbon content in the sponge gland is reduced with a lower gas consumption in the shaft furnace.
    The costs associated with installation and equipment are reduced. It eliminates the need for a tuyere stock photography.
