1. method that is used to make molten iron comprises step:

  • Come production iron content mixture by drying and compound iron ore and additive;

    Make to contain iron mixture, like this mixture is reduced and calcines to be converted into reducing material thus by one or more fluidized-beds that connect successively;

    Form the coal packed bed, this coal packed bed is a thermal source, and reducing material is fusion therein;

    Reducing material is loaded into the coal packed bed, and provides oxygen to make molten iron to the coal packed bed;

    AndTo offer fluidized-bed from the reducing gas that the coal packed bed is discharged,Wherein mixture is being converted in the step of reducing material, oxygen is provided to directly that reducing gas flows into the zone of fluidized-bed and in this zonal combustion.
