Abstract: Process control for molten metal involves using a dynamic computer process model together with a correction model. To produce a molten metal in a metallurgical plant, a process model is used with the plant computer control. The process model has the behavior for at least one variable process parameter between an actual process value, a setting value, and a final process value. The process model takes the actual process value data to a given time point, as the temperature and/or the chemical composition where a computer simulation gives the direct time point where the actual process value gives the final process value at a later point in time. On deviations of the simulated process value from a nominal value, corrections are computed and the actual process value is altered accordingly. The actual process value is repeated from the data taken to the further time point. The process module has at least one module with intelligent self-optimizing e.g. with a neural network.

Abstract: In an electric arc furnace arrangement for producing steel by melting scrap (27), in particular scrap iron, and/or sponge iron and/or pig iron as well as additives in a furnace vessel (1), at least one graphite electrode (11), movable in its longitudinal direction, projects into the furnace vessel and an electric arc (26) is struck between the graphite electrode (11) and the charge (27). To achieve a particularly high energy input - the graphite electrode (11) projects into a lower part (8) of the furnace vessel (1) from the side and - in the region of the graphite electrode (11), the lower part (8) has a widened portion (8, 9) projecting radially outwards relative to the upper part (10) (Fig. 1).

Abstract: A plant for the production of molten metals, includes a melting vessel and a metallurgical vessel receiving the melt from the melting vessel for aftertreating the melt and closed by a lid. The melting vessel has a tap opening for the melt provided on the bottom level of the melting vessel and located on the periphery of the melting vessel. The tap opening is positioned above a pour-in opening of the metallurgical vessel. In order to ensure a continuous melting procedure, the pour-in opening of the metallurgical vessel following the melting vessel is provided above a melt guiding chute arranged within the metallurgical vessel.

Abstract: Steel is produced in a DC arc furnace with peripheral C electrodes inclined at an angle and directed towards a bottom anode. The arc is formed between the electrodes and the anode. A gas burner projects into the furnace at a level above that of the electrodes. After scrap is charged, natural gas is supplied through the electrode cavities and is broken down by the arc.
