Abstract:
    In a method of producing molten pig iron or steel pre-products from particulate ferrous material, as well as of producing reduction gas in a melt-down gasifier by adding coal and by blowing in oxygen-containing gas by means of nozzle pipes penetrating the wall of the melt-down gasifier, a fixed bed formed of coke particles, through which the oxygen-containing gas flows and a superposed fluidized bed of coke particles are formed, and the ferrous material is charged onto the fluidized bed. Below the fixed bed through which oxygen-containing gas flows, a fixed bed of coke particles not passed through by gas is provided, and the fluidized bed above the fixed bed passed through by oxygen-containing gas is passed through by a gas free from oxygen or having a low oxygen content.
