Charter manufacturing apparatus using iron ore

摘要

The present invention relates to an apparatus for producing molten iron by reducing the iron ore by using a two-stage fluidized bed reduction apparatus and then melt reduction in a molten gasifier, the dispersion of fine powder generated during the flow reduction of the iron ore having a wide particle size distribution To provide a manufacturing apparatus of molten iron that can be minimized, the purpose is.;The present invention is a device for producing molten iron using the iron-iron ore, the first particle of the particle size distribution is charged from the hopper and the fine particles are scattered and the primary ore only the iron ore of the primary or reduced by the turbulent fluidized bed Fluidized bed furnace; A second fluidized bed furnace for first reducing the fine iron ore scattered from the first fluidized bed by the bubble fluidized bed; A third fluidized bed furnace for reducing the reduced iron discharged by primary reduction in the first fluidized bed furnace and the second fluidized bed furnace by the bubble fluidized bed; And a molten gasifier that melts secondary reduced reduced iron in the third fluidized bed furnace to produce molten iron.
