Abstract (en)

[origin: EP1310573A2] 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.
