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.

Method and device for producing a static bed

A method for loading a pourable material in a container, the material being supplied by gravity forces through a channel which is arranged in the opening of the container. In order to obtain a desired material distribution in the container, the material, a little bit before the passage thereof through the opening, i.e. inside the channel, is exposed to forces modifying the displacement direction of the material given by the channel and the gravity forces.
