Device for controlling an arc furnace installation

A method for optimizing the operation of a metallurgical plant using a model by modeling supply and discharge media streams, predetermining structure parameters which define the media streams, linking the media streams to one another, predetermining starting parameters which describe initial states, predetermining input operating parameters, determining and outputting output operating parameters, and determining and outputting end parameters, which describe end states of the units, by the model, predetermining the structure parameters to an optimization computer by a user and transmitting the parameters from the optimization computer to a model, and determining optimized operating parameters by the optimization computer on the basis of the starting parameters and an assessment criterion in accordance with an optimization algorithm using the model, wherein the assessment criterion is predetermined to the optimization computer by the user.

Mathematical model for a metallurgical plant, and method for optimizing the operation of a metallurgical plant using a model

A casting-rolling plant and a method of operating a casting-rolling plant are disclosed. At least one slab production line () and at least one mill train () as well as at least one slab feeding device () that is independent of the slab production line () with respect to the production process are provided. In order to achieve a higher throughput in the production of strip material, the slab feeding device () takes over slab feed to the mill train () during a production break of the slab production line () in accordance with logistic and/or manufacturing standards up to a maximum output possible.

Method for operating a casting-rolling plant

A method and device for producing a strand of metal by means of a continuous-casting installation which has at least one cooling device for cooling the strand, the cooling device being assigned at least one reduction stand for reducing the thickness of the strand, the strand, during the thickness reduction, having a solidified skin and a liquid core. The cooling is set, by means of a temperature and solidification model, in such a manner that the solidification boundary between the solidified skin and the liquid core when the strand enters the reduction stand corresponds to a predetermined set solidification boundary between the solidified skin and the liquid core.
