    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: To be able to produce metal melts using any metal carriers incurring in metallurgical practice as the charging materials, namely in the most diverse quantitative compositions, a plant for producing metal melts is provided with the following characteristic features:an electric arc furnace vessel (1) provided with one charging opening (11, 21) for a metal melt and/or scrap and/or direct reduced metal, in particular direct reduced iron, and/or ore and at least one electrode (16) and one slag tapping means (22),an oxygen-blowing converter vessel (3) provided with one melt tapping means (41),wherein the oxygen-blowing converter vessel (3) and the electric arc furnace vessel (1) form a unit which is connected via an overflow weir (34) and which is rigidly mounted on the foundation and,wherein the bath surface related specifically to the bath volume is smaller in the oxygen-blowing converter vessel (3) than in the electric arc furnace vessel (1) andthe oxygen-blowing converter vessel (3) shares a common reaction space with the electric arc furnace vessel (1), which space is arranged above the bath level of these vessels. (FIG. 1).
