ABSTRACT:
Apparatus and process for producing a fixed bed in a metallurgical unit, preferably for producing pig iron or primary steel products from iron-containing charge materials, in particular in a melted gasifier, in which a lumpy bulk material, which contains ore-containing and carbon-containing constituents, prereduced iron ore, preferably sponge iron, and preferably lumpy, coal, is charged onto a surface. Through mixing of the ore-containing constituent with the carbon-containing constituent of the bulk material takes place. The entire ore-containing constituent is charged onto an active circumferential or peripheral region of the fixed bed, at which the thorough, preferably uniform mixing of the ore-containing constituent with the carbon-containing constituent of the bulk material takes place preferably outward of the center. A device scatters the stream of bulk material aver the surface and less of the material is scattered at the center, so that heavier grain lumps segregate themselves toward the center.
